144-518: Quetta ( / ˈ k w ɛ t ə / ; Urdu : کوئٹہ , ko'eṭa , [ˈkweːʈə] , Pashto : کوټه ) is the capital and largest city of the Pakistani province of Balochistan . It is the ninth largest city in Pakistan , with an estimated population of over 1.5 million in 2024. It is situated in the south-west of the country, lying in a valley surrounded by mountains on all sides. Quetta

288-642: A dialect continuum ranging from Persianised to Sanskritised vocabulary, but now they are more and more different in words due to politics. Old Urdu dictionaries also contain most of the Sanskrit words now present in Hindi. Mutual intelligibility decreases in literary and specialised contexts that rely on academic or technical vocabulary. In a longer conversation, differences in formal vocabulary and pronunciation of some Urdu phonemes are noticeable, though many native Hindi speakers also pronounce these phonemes. At

432-535: A monsoon season of heavy rainfall. Highest rainfall during 24 hours in Quetta is 113 millimetres (4.4 in) which was recorded on 17 December 2000, Highest monthly rainfall of 232.4 millimetres (9.15 in) was recorded in March 1982 which was also the year of the highest annual rainfall, 949.8 millimetres (37.39 in). In the winter, snowfall has become quite erratic (December, January and February). The city saw

576-442: A common Sanskrit - and Prakrit -derived vocabulary base, phonology , syntax , and grammar, making them mutually intelligible during colloquial communication . While formal Urdu draws literary, political, and technical vocabulary from Persian , formal Hindi draws these aspects from Sanskrit; consequently, the two languages' mutual intelligibility effectively decreases as the factor of formality increases. Urdu originated in

720-568: A cooler West Pacific and a warmer East Pacific, leading to a shift of cloudiness and rainfall towards the East Pacific. This situation is called El Niño. The opposite occurs if trade winds are stronger than average, leading to a warmer West Pacific and a cooler East Pacific. This situation is called La Niña and is associated with increased cloudiness and rainfall over the West Pacific. The close relationship between ocean temperatures and

864-406: A core vocabulary of native Sanskrit and Prakrit derived words and a significant number of Arabic and Persian loanwords, with a consensus of linguists considering them to be two standardised forms of the same language and consider the differences to be sociolinguistic ; a few classify them separately. The two languages are often considered to be a single language (Hindustani or Hindi-Urdu) on

1008-602: A decrease in the strength of the Pacific trade winds , and a reduction in rainfall over eastern and northern Australia. La Niña episodes are defined as sustained cooling of the central and eastern tropical Pacific Ocean, thus resulting in an increase in the strength of the Pacific trade winds , and the opposite effects in Australia when compared to El Niño. Although the Southern Oscillation Index has

1152-672: A distinction between Urdu and Hindi, leading to the Hindi–Urdu controversy . According to 2022 estimates by Ethnologue and The World Factbook , produced by the Central Intelligence Agency (CIA), Urdu is the 10th-most widely spoken language in the world , with 230 million total speakers, including those who speak it as a second language . The name Urdu was first used by the poet Ghulam Hamadani Mushafi around 1780 for Hindustani language even though he himself also used Hindavi term in his poetry to define

1296-546: A heavy influence on both as a co-official language. According to Bruce (2021), Urdu has adapted English words since the eighteenth century. A movement towards the hyper-Persianisation of an Urdu emerged in Pakistan since its independence in 1947 which is "as artificial as" the hyper-Sanskritised Hindi that has emerged in India; hyper-Persianisation of Urdu was prompted in part by the increasing Sanskritisation of Hindi. However,

1440-489: A larger EP ENSO occurrence, or even displaying opposite conditions from the observed ones in the other Niño regions when accompanied by Modoki variations. ENSO Costero events usually present more localized effects, with warm phases leading to increased rainfall over the coast of Ecuador, northern Peru and the Amazon rainforest , and increased temperatures over the northern Chilean coast, and cold phases leading to droughts on

1584-518: A literary medium for Indian writers from the Bombay Presidency, Bengal, Orissa Province, and Tamil Nadu as well. As Urdu and Hindi became means of religious and social construction for Muslims and Hindus respectively, each register developed its own script. According to Islamic tradition, Arabic , the language of Muhammad and the Qur'an , holds spiritual significance and power. Because Urdu

1728-553: A long station record going back to the 1800s, its reliability is limited due to the latitudes of both Darwin and Tahiti being well south of the Equator, so that the surface air pressure at both locations is less directly related to ENSO. To overcome this effect, a new index was created, named the Equatorial Southern Oscillation Index (EQSOI). To generate this index, two new regions, centered on

1872-469: A municipal corporation consisting of 66 ward members which elects a mayor and a deputy mayor. In addition, Quetta Development Authority is responsible for provision of municipal services for the city. Quetta is on the western side of Pakistan and is connected to the rest of the country by a network of roads, railways and its international airport close to its centre. At an altitude of 1,605 metres (5,266 feet) above sea level, Quetta International Airport

2016-411: A negative SSH anomaly (lowered sea level) via contraction. The El Niño–Southern Oscillation is a single climate phenomenon that quasi-periodically fluctuates between three phases: Neutral, La Niña or El Niño. La Niña and El Niño are opposite phases which require certain changes to take place in both the ocean and the atmosphere before an event is declared. The cool phase of ENSO is La Niña, with SST in

2160-595: A notable novel being Umrao Jaan Ada . According to the Navadirul Alfaz by Khan-i Arzu, the "Zaban-e Urdu-e Shahi" [language of the Imperial Camp] had attained special importance in the time of Alamgir ". By the end of the reign of Aurangzeb in the early 1700s, the common language around Delhi began to be referred to as Zaban-e-Urdu , a name derived from the Turkic word ordu (army) or orda and

2304-702: A phonological level, speakers of both languages are frequently aware of the Perso-Arabic or Sanskrit origins of their word choice, which affects the pronunciation of those words. Urdu speakers will often insert vowels to break up consonant clusters found in words of Sanskritic origin, but will pronounce them correctly in Arabic and Persian loanwords. As a result of religious nationalism since the partition of British India and continued communal tensions, native speakers of both Hindi and Urdu frequently assert that they are distinct languages. The grammar of Hindi and Urdu

2448-589: A policy continued by the Mughal Empire , which extended over most of northern South Asia from the 16th to 18th centuries and cemented Persian influence on Hindustani. Urdu was patronised by the Nawab of Awadh and in Lucknow , the language was refined, being not only spoken in the court, but by the common people in the city—both Hindus and Muslims; the city of Lucknow gave birth to Urdu prose literature, with

2592-517: A quarter of the planet, and particularly in the form of temperature at the ocean surface, can have a significant effect on weather across the entire planet. Tropical instability waves visible on sea surface temperature maps, showing a tongue of colder water, are often present during neutral or La Niña conditions. La Niña is a complex weather pattern that occurs every few years, often persisting for longer than five months. El Niño and La Niña can be indicators of weather changes across

2736-425: A secondary peak in sea surface temperature across the far eastern equatorial Pacific Ocean sometimes follows the initial peak. An especially strong Walker circulation causes La Niña, which is considered to be the cold oceanic and positive atmospheric phase of the broader El Niño–Southern Oscillation (ENSO) weather phenomenon, as well as the opposite of El Niño weather pattern, where sea surface temperature across

2880-507: A sectarian divide of "Urdu" for Muslims and "Hindi" for Hindus, a divide that was formalised with the partition of colonial India into the Dominion of India and the Dominion of Pakistan after independence (though there are Hindu poets who continue to write in Urdu, including Gopi Chand Narang and Gulzar ). Urdu had been used as a literary medium for British colonial Indian writers from

3024-465: A severe drought from 1999 to 2001 during which the city did not receive snowfall and below normal rains. In 2002, the city received snow after a gap of five years. In 2004 and 2005, the city received normal rains after three years without snowfall while in 2006, 2007 and 2009 the city received no snow. In 2008, it received a snowfall of 10 centimetres (4 in) in four hours on 29 January, followed on 2 February by 25.4 centimetres (10 in) in 10 hours –

3168-481: A significant role in the development of the Urdu register. Hindi became the distinct register spoken by those who sought to construct a Hindu identity in the face of colonial rule. As Hindi separated from Hindustani to create a distinct spiritual identity, Urdu was employed to create a definitive Islamic identity for the Muslim population in India. Urdu's use was not confined only to northern India – it had been used as

3312-614: A symbol of their religious identity. Hindus in northwestern India, under the Arya Samaj agitated against the sole use of the Perso-Arabic script and argued that the language should be written in the native Devanagari script, which triggered a backlash against the use of Hindi written in Devanagari by the Anjuman-e-Islamia of Lahore. Hindi in the Devanagari script and Urdu written in the Perso-Arabic script established

3456-419: A uniting language. Urdu was chosen as a symbol of unity for the new Dominion of Pakistan in 1947, because it had already served as a lingua franca among Muslims in north and northwest of British Indian Empire . Urdu is also seen as a repertory for the cultural and social heritage of Pakistan. While Urdu and Islam together played important roles in developing the national identity of Pakistan, disputes in

3600-464: A very significant number among the nearly 800 districts of India, there is a small Urdu-speaking minority at least. In Araria district , Bihar, there is a plurality of Urdu speakers and near-plurality in Hyderabad district, Telangana (43.35% Telugu speakers and 43.24% Urdu speakers). Some Indian Muslim schools ( Madrasa ) teach Urdu as a first language and have their own syllabi and exams. In fact,

3744-670: Is a trade and communication centre between the two countries. The city is near the Bolan Pass , which was on a major gateway from Central Asia to South Asia . The name Quetta is a variation of the Pashto word Kwatkōṭ , or kōta meaning "fortress". Quetta was formerly known as Shalkot ( Pashto : ښالکوټ ) Modern day Quetta was captured by Sultan Mahmud Ghaznavi during his invasion of South Asia . In 1543, Mughal emperor Humayun came to Quetta en route to Safavid Persia , leaving his son and future Mughal emperor Akbar here. In 1709,

3888-614: Is an Eighth Schedule language , the status and cultural heritage of which are recognised by the Constitution of India ; and it also has an official status in several Indian states. In Nepal , Urdu is a registered regional dialect and in South Africa , it is a protected language in the constitution. It is also spoken as a minority language in Afghanistan and Bangladesh , with no official status. Urdu and Hindi share

4032-603: Is an oscillation in surface air pressure between the tropical eastern and the western Pacific Ocean waters. The strength of the Southern Oscillation is measured by the Southern Oscillation Index (SOI). The SOI is computed from fluctuations in the surface air pressure difference between Tahiti (in the Pacific) and Darwin, Australia (on the Indian Ocean). El Niño episodes have negative SOI, meaning there

4176-480: Is at an average elevation of 1,680 metres (5,510 feet) above sea level, making it Pakistan's highest altitude major city. The city is known as the "Fruit Garden of Pakistan" due to the numerous fruit orchards in and around it and the large variety of fresh and dried fruits produced there. Located in northern Balochistan near the Pakistan-Afghanistan border and the road across to Kandahar , Quetta

4320-405: Is known as Ekman transport . Colder water from deeper in the ocean rises along the continental margin to replace the near-surface water. This process cools the East Pacific because the thermocline is closer to the ocean surface, leaving relatively little separation between the deeper cold water and the ocean surface. Additionally, the northward-flowing Humboldt Current carries colder water from

4464-520: Is longer, it is classified as an El Niño "episode". It is thought that there have been at least 30 El Niño events between 1900 and 2024, with the 1982–83 , 1997–98 and 2014–16 events among the strongest on record. Since 2000, El Niño events have been observed in 2002–03, 2004–05, 2006–07, 2009–10, 2014–16 , 2018–19, and 2023–24 . Major ENSO events were recorded in the years 1790–93, 1828, 1876–78, 1891, 1925–26, 1972–73, 1982–83, 1997–98, 2014–16, and 2023–24. During strong El Niño episodes,

4608-561: Is lower pressure over Tahiti and higher pressure in Darwin. La Niña episodes on the other hand have positive SOI, meaning there is higher pressure in Tahiti and lower in Darwin. Low atmospheric pressure tends to occur over warm water and high pressure occurs over cold water, in part because of deep convection over the warm water. El Niño episodes are defined as sustained warming of the central and eastern tropical Pacific Ocean, thus resulting in

4752-527: Is not officially recognised by the Government of Bangladesh . The Urdu spoken by Stranded Pakistanis in Bangladesh is different from this dialect. Many bilingual or multi-lingual Urdu speakers, being familiar with both Urdu and English, display code-switching (referred to as " Urdish ") in certain localities and between certain social groups. On 14 August 2015, the Government of Pakistan launched

4896-488: Is one variety, is spoken much more widely, forming the third most commonly spoken language in the world, after Mandarin and English . The syntax (grammar), morphology , and the core vocabulary of Urdu and Hindi are essentially identical – thus linguists usually count them as one single language, while some contend that they are considered as two different languages for socio-political reasons. Owing to interaction with other languages, Urdu has become localised wherever it

5040-593: Is read and written as in other parts of India. A number of daily newspapers and several monthly magazines in Urdu are published in these states. Dhakaiya Urdu is a dialect native to the city of Old Dhaka in Bangladesh , dating back to the Mughal era . However, its popularity, even among native speakers, has been gradually declining since the Bengali Language Movement in the 20th century. It

5184-552: Is said to have arisen as the "language of the camp", or " Zaban-i-Ordu " means " Language of High camps " or natively " Lashkari Zaban " means " Language of Army " even though term Urdu held different meanings at that time. It is recorded that Aurangzeb spoke in Hindvi, which was most likely Persianized, as there are substantial evidence that Hindvi was written in the Persian script in this period. During this time period Urdu

5328-542: Is shared, though formal Urdu makes more use of the Persian "-e-" izafat grammatical construct (as in Hammam-e-Qadimi , or Nishan-e-Haider ) than does Hindi. The following table shows the number of Urdu speakers in some countries. El Ni%C3%B1o-Southern Oscillation El Niño is associated with higher than normal air sea level pressure over Indonesia, Australia and across the Indian Ocean to

Urdu is also spoken by large numbers of immigrants and their children in the major urban centres of the United Kingdom , the United States, Canada, Germany, New Zealand, Norway, and Australia. Along with Arabic , Urdu is among the immigrant languages with the most speakers in Catalonia . Religious and social atmospheres in early nineteenth century India played

5616-492: Is spoken, including in Pakistan. Urdu in Pakistan has undergone changes and has incorporated and borrowed many words from regional languages, thus allowing speakers of the language in Pakistan to distinguish themselves more easily and giving the language a decidedly Pakistani flavor. Similarly, the Urdu spoken in India can also be distinguished into many dialects such as the Standard Urdu of Lucknow and Delhi , as well as

5760-522: Is the Bjerknes feedback (named after Jacob Bjerknes in 1969) in which the atmospheric changes alter the sea temperatures that in turn alter the atmospheric winds in a positive feedback. Weaker easterly trade winds result in a surge of warm surface waters to the east and reduced ocean upwelling on the equator . In turn, this leads to warmer sea surface temperatures (called El Niño), a weaker Walker circulation (an east-west overturning circulation in

The two phenomena last a year or so each and typically occur every two to seven years with varying intensity, with neutral periods of lower intensity interspersed. El Niño events can be more intense but La Niña events may repeat and last longer. A key mechanism of ENSO

6624-575: The Bombay , Bengal , Orissa , and Hyderabad State as well. Before independence, Muslim League leader Muhammad Ali Jinnah advocated the use of Urdu, which he used as a symbol of national cohesion in Pakistan. After the Bengali language movement and the separation of former East Pakistan , Urdu was recognised as the sole national language of Pakistan in 1973, although English and regional languages were also granted official recognition. Following

6768-671: The Central Hindi Directorate was established earlier in 1960, and the promotion of Hindi is better funded and more advanced, while the status of Urdu has been undermined by the promotion of Hindi. Private Indian organisations such as the Anjuman-e-Tariqqi Urdu, Deeni Talimi Council and Urdu Mushafiz Dasta promote the use and preservation of Urdu, with the Anjuman successfully launching a campaign that reintroduced Urdu as an official language of Bihar in

6912-687: The Dakhni ( Deccan ) of South India. Because of Urdu's similarity to Hindi , speakers of the two languages can easily understand one another if both sides refrain from using literary vocabulary. Although Urdu is widely spoken and understood throughout all of Pakistan, only 9% of Pakistan's population spoke Urdu according to the 2023 Pakistani census . Most of the nearly three million Afghan refugees of different ethnic origins (such as Pashtun , Tajik , Uzbek , Hazarvi , and Turkmen ) who stayed in Pakistan for over twenty-five years have also become fluent in Urdu. Muhajirs since 1947 have historically formed

The West Pacific lacks a cold ocean current and has less upwelling as the trade winds are usually weaker than in the East Pacific, allowing the West Pacific to reach warmer temperatures. These warmer waters provide energy for

There have been attempts to purge Urdu of native Prakrit and Sanskrit words, and Hindi of Persian loanwords – new vocabulary draws primarily from Persian and Arabic for Urdu and from Sanskrit for Hindi. English has exerted

9504-569: The Bjerknes feedback naturally triggers negative feedbacks that end and reverse the abnormal state of the tropical Pacific. This perspective implies that the processes that lead to El Niño and La Niña also eventually bring about their end, making ENSO a self-sustaining process. Other theories view the state of ENSO as being changed by irregular and external phenomena such as the Madden–Julian oscillation , tropical instability waves , and westerly wind bursts . The three phases of ENSO relate to

Although these associated changes in the ocean and atmosphere often occur together, the state of the atmosphere may resemble a different ENSO phase than the state of the ocean or vice versa. Because their states are closely linked, the variations of ENSO may arise from changes in both the ocean and atmosphere and not necessarily from an initial change of exclusively one or

10224-440: The El Niños of 2006-07 and 2014-16 were also Central Pacific El Niños. Recent years when La Niña Modoki events occurred include 1973–1974, 1975–1976, 1983–1984, 1988–1989, 1998–1999, 2000–2001, 2008–2009, 2010–2011, and 2016–2017.

Sea surface height (SSH) changes up or down by several centimeters in Pacific equatorial region with the ESNO: El Niño causes a positive SSH anomaly (raised sea level) because of thermal expansion while La Niña causes

10656-636: The Heathens, or from the Persians, or other Nations. In 1715, a complete literary Diwan in Rekhta was written by Nawab Sadruddin Khan . An Urdu-Persian dictionary was written by Khan-i Arzu in 1751 in the reign of Ahmad Shah Bahadur . The name Urdu was first introduced by the poet Ghulam Hamadani Mushafi around 1780. As a literary language, Urdu took shape in courtly, elite settings. While Urdu retained

10800-405: The Indian government do not actively support the preservation of Urdu in professional and official spaces. Because the Pakistani government proclaimed Urdu the national language at Partition, the Indian state and some religious nationalists began in part to regard Urdu as a 'foreign' language, to be viewed with suspicion. Urdu advocates in India disagree whether it should be allowed to write Urdu in

10944-425: The Indian subcontinent (12th to 16th centuries) led to the development of Hindustani as a product of a composite Ganga-Jamuni tehzeeb . In cities such as Delhi, the ancient language Old Hindi began to acquire many Persian loanwords and continued to be called "Hindi" and later, also "Hindustani". An early literary tradition of Hindavi was founded by Amir Khusrau in the late 13th century. After

11088-531: The Pacific Ocean and are dependent on agriculture and fishing. In climate change science, ENSO is known as one of the internal climate variability phenomena. Future trends in ENSO due to climate change are uncertain, although climate change exacerbates the effects of droughts and floods. The IPCC Sixth Assessment Report summarized the scientific knowledge in 2021 for the future of ENSO as follows: "In

11232-457: The Walker circulation, which was named after Gilbert Walker who discovered the Southern Oscillation during the early twentieth century. The Walker circulation is an east-west overturning circulation in the vicinity of the equator in the Pacific. Upward air is associated with high sea temperatures, convection and rainfall, while the downward branch occurs over cooler sea surface temperatures in

11376-457: The West Pacific northeast of Australia averages around 28–30 °C (82–86 °F). SSTs in the East Pacific off the western coast of South America are closer to 20 °C (68 °F). Strong trade winds near the equator push water away from the East Pacific and towards the West Pacific. This water is slowly warmed by the Sun as it moves west along the equator. The ocean surface near Indonesia

11520-465: The West Pacific to a depth of about 30 m (90 ft) in the East Pacific. Cooler deep ocean water takes the place of the outgoing surface waters in the East Pacific, rising to the ocean surface in a process called upwelling . Along the western coast of South America, water near the ocean surface is pushed westward due to the combination of the trade winds and the Coriolis effect . This process

11664-445: The absorption of vocabulary from various regional Pakistani languages, while some Urdu vocabularies has also been assimilated by Pakistan's regional languages. Some who are from a non-Urdu background now can read and write only Urdu. With such a large number of people(s) speaking Urdu, the language has acquired a peculiar Pakistani flavor further distinguishing it from the Urdu spoken by native speakers, resulting in more diversity within

11808-704: The area of the Ganges-Yamuna Doab , though significant development occurred in the Deccan Plateau . In 1837, Urdu became an official language of the British East India Company , replacing Persian across northern India during Company rule ; Persian had until this point served as the court language of various Indo-Islamic empires . Religious, social, and political factors arose during the European colonial period that advocated

11952-429: The asymmetric nature of the warm and cold phases of ENSO, some studies could not identify similar variations for La Niña, both in observations and in the climate models, but some sources could identify variations on La Niña with cooler waters on central Pacific and average or warmer water temperatures on both eastern and western Pacific, also showing eastern Pacific Ocean currents going to the opposite direction compared to

12096-438: The atmosphere) and even weaker trade winds. Ultimately the warm waters in the western tropical Pacific are depleted enough so that conditions return to normal. The exact mechanisms that cause the oscillation are unclear and are being studied. Each country that monitors the ENSO has a different threshold for what constitutes an El Niño or La Niña event, which is tailored to their specific interests. El Niño and La Niña affect

12240-436: The atmospheric and oceanic conditions. When the tropical Pacific roughly reflects the average conditions, the state of ENSO is said to be in the neutral phase. However, the tropical Pacific experiences occasional shifts away from these average conditions. If trade winds are weaker than average, the effect of upwelling in the East Pacific and the flow of warmer ocean surface waters towards the West Pacific lessen. This results in

12384-413: The city's heaviest snowfall in a decade. During the winter of 2010, it received no snow and saw below normal rains due to the presence of El-Nino over Pakistan. According to the 2023 Census of Pakistan , the population of the city was a total of 1,565,546. This makes it the largest city in Balochistan province and one of the major cities of Pakistan. Quetta is one of the most ethnically diverse cities in

12528-622: The conquest of the Deccan , and a subsequent immigration of noble Muslim families into the south, a form of the language flourished in medieval India as a vehicle of poetry, (especially under the Bahmanids ), and is known as Dakhini , which contains loanwords from Telugu and Marathi . From the 13th century until the end of the 18th century; the language now known as Urdu was called Hindi , Hindavi , Hindustani , Dehlavi , Dihlawi , Lahori , and Lashkari . The Delhi Sultanate established Persian as its official language in India,

12672-591: The correlation and study past El Niño episodes. More generally, there is no scientific consensus on how/if climate change might affect ENSO. There is also a scientific debate on the very existence of this "new" ENSO. A number of studies dispute the reality of this statistical distinction or its increasing occurrence, or both, either arguing the reliable record is too short to detect such a distinction, finding no distinction or trend using other statistical approaches, or that other types should be distinguished, such as standard and extreme ENSO. Likewise, following

12816-461: The country. The city has a Pashtun plurality followed by Balochs , Hazaras , Brahui , Punjabis and Muhajir people . Urdu being the national language is used and understood by all the residents and serves as a lingua franca . According to Reuters and the BBC , there are as many as 500,000-600,000 Hazaras living in Quetta and its surrounding areas. At the local level, the city is governed by

12960-402: The country. The extensive network of Pakistan Railways connects Quetta to Karachi in the south, by a 863 km (536 mi) track, Lahore in the northeast (1,170 km or 727 miles) and Peshawar further northeast (1,587 km or 986 miles). A metalled road runs alongside the railway that connects Quetta to Karachi via the nearby town of Sibi to Jacobabad and Rohri in the plain of

13104-559: The currents in traditional La Niñas. Coined by the Peruvian Comité Multisectorial Encargado del Estudio Nacional del Fenómeno El Niño (ENFEN), ENSO Costero, or ENSO Oriental, is the name given to the phenomenon where the sea-surface temperature anomalies are mostly focused on the South American coastline, especially from Peru and Ecuador. Studies point many factors that can lead to its occurrence, sometimes accompanying, or being accompanied, by

13248-415: The early 21st century an increasing percentage of Indian Muslims began switching to Hindi due to socio-economic factors, such as Urdu being abandoned as the language of instruction in much of India, and having limited employment opportunities compared to Hindi, English and regional languages. The number of Urdu speakers in India fell 1.5% between 2001 and 2011 (then 5.08 million Urdu speakers), especially in

13392-469: The east. During El Niño, as the sea surface temperatures change so does the Walker Circulation. Warming in the eastern tropical Pacific weakens or reverses the downward branch, while cooler conditions in the west lead to less rain and downward air, so the Walker Circulation first weakens and may reverse.   The Southern Oscillation is the atmospheric component of ENSO. This component

13536-614: The eastern Pacific below average, and air pressure high in the eastern Pacific and low in the western Pacific. The ENSO cycle, including both El Niño and La Niña, causes global changes in temperature and rainfall. If the temperature variation from climatology is within 0.5 °C (0.9 °F), ENSO conditions are described as neutral. Neutral conditions are the transition between warm and cold phases of ENSO. Sea surface temperatures (by definition), tropical precipitation, and wind patterns are near average conditions during this phase. Close to half of all years are within neutral periods. During

13680-479: The eastern Pacific. However, in the 1990s and 2000s, variations of ENSO conditions were observed, in which the usual place of the temperature anomaly (Niño 1 and 2) is not affected, but an anomaly also arises in the central Pacific (Niño 3.4). The phenomenon is called Central Pacific (CP) ENSO, "dateline" ENSO (because the anomaly arises near the dateline ), or ENSO "Modoki" (Modoki is Japanese for "similar, but different"). There are variations of ENSO additional to

13824-404: The eastern equatorial part of the central Pacific Ocean will be lower than normal by 3–5 °C (5.4–9 °F). The phenomenon occurs as strong winds blow warm water at the ocean's surface away from South America, across the Pacific Ocean towards Indonesia. As this warm water moves west, cold water from the deep sea rises to the surface near South America. The movement of so much heat across

13968-567: The eastern portion of the country as in a conventional EP La Niña. Also, La Niña Modoki increases the frequency of cyclonic storms over Bay of Bengal , but decreases the occurrence of severe storms in the Indian Ocean overall. The first recorded El Niño that originated in the central Pacific and moved toward the east was in 1986. Recent Central Pacific El Niños happened in 1986–87, 1991–92, 1994–95, 2002–03, 2004–05 and 2009–10. Furthermore, there were "Modoki" events in 1957–59, 1963–64, 1965–66, 1968–70, 1977–78 and 1979–80. Some sources say that

14112-737: The following years: Transitional phases at the onset or departure of El Niño or La Niña can also be important factors on global weather by affecting teleconnections . Significant episodes, known as Trans-Niño, are measured by the Trans-Niño index (TNI). Examples of affected short-time climate in North America include precipitation in the Northwest US and intense tornado activity in the contiguous US. The first ENSO pattern to be recognised, called Eastern Pacific (EP) ENSO, to distinguish if from others, involves temperature anomalies in

14256-534: The global climate and disrupt normal weather patterns, which as a result can lead to intense storms in some places and droughts in others. El Niño events cause short-term (approximately 1 year in length) spikes in global average surface temperature while La Niña events cause short term surface cooling. Therefore, the relative frequency of El Niño compared to La Niña events can affect global temperature trends on timescales of around ten years. The countries most affected by ENSO are developing countries that are bordering

14400-409: The globe. Atlantic and Pacific hurricanes can have different characteristics due to lower or higher wind shear and cooler or warmer sea surface temperatures. La Niña events have been observed for hundreds of years, and occurred on a regular basis during the early parts of both the 17th and 19th centuries. Since the start of the 20th century, La Niña events have occurred during

14544-529: The grammar and core Indo-Aryan vocabulary of the local Indian dialect Khariboli, it adopted the Nastaleeq writing system – which was developed as a style of Persian calligraphy. Throughout the history of the language, Urdu has been referred to by several other names: Hindi, Hindavi, Rekhta, Urdu-e-Muallah, Dakhini , Moors and Dehlavi . In 1773, the Swiss French soldier Antoine Polier notes that

14688-480: The independence movement. But after the 1947 Partition , when it was chosen as the national language of Pakistan to unite all inhabitants with one linguistic identity, it faced serious competition primarily from Bengali (spoken by 56% of the total population, mostly in East Pakistan until that attained independence in 1971 as Bangladesh ), and after 1971 from English. Both pro-independence elites that formed

14832-471: The internal climate variability phenomena. The other two main ones are Pacific decadal oscillation and Atlantic multidecadal oscillation . La Niña impacts the global climate and disrupts normal weather patterns, which can lead to intense storms in some places and droughts in others. El Niño events cause short-term (approximately 1 year in length) spikes in global average surface temperature while La Niña events cause short term cooling. Therefore,

14976-554: The language as " Moors " or "Moorish jargon". John Gilchrist was the first in British India to begin a systematic study on Urdu and began to use the term "Hindustani" what the majority of Europeans called "Moors", authoring the book The Strangers's East Indian Guide to the Hindoostanee or Grand Popular Language of India (improperly Called Moors) . Urdu was then promoted in colonial India by British policies to counter

15120-458: The language in the Perso-Arabic script in courts and government offices, though Hindus continued to employ the Devanagari script in certain literary and religious contexts. Through the late 19th century, people did not view Urdu and Hindi as being two distinct languages, though in urban areas, the standardised Hindustani language was increasingly being referred to as Urdu and written in the Perso-Arabic script. Urdu and English replaced Persian as

15264-575: The language of Bollywood films tend to contain a large number of Persian and Arabic words and thus considered to be "Urdu" in a sense, especially in songs. India has more than 3,000 Urdu publications, including 405 daily Urdu newspapers. Newspapers such as Neshat News Urdu , Sahara Urdu , Daily Salar , Hindustan Express , Daily Pasban , Siasat Daily , The Munsif Daily and Inqilab are published and distributed in Bangalore, Malegaon, Mysore, Hyderabad, and Mumbai . Outside South Asia, it

15408-883: The language. In India, Urdu is spoken in places where there are large Muslim minorities or cities that were bases for Muslim empires in the past. These include parts of Uttar Pradesh , Madhya Pradesh , Bihar , Telangana , Andhra Pradesh , Maharashtra ( Marathwada and Konkanis), Karnataka and cities such as Hyderabad , Lucknow , Delhi , Malerkotla , Bareilly , Meerut , Saharanpur , Muzaffarnagar , Roorkee , Deoband , Moradabad , Azamgarh , Bijnor , Najibabad , Rampur , Aligarh , Allahabad , Gorakhpur , Agra , Firozabad , Kanpur , Badaun , Bhopal , Hyderabad , Aurangabad , Bangalore , Kolkata , Mysore , Patna , Darbhanga , Gaya , Madhubani , Samastipur , Siwan , Saharsa , Supaul , Muzaffarpur , Nalanda , Munger , Bhagalpur , Araria , Gulbarga , Parbhani , Nanded , Malegaon , Bidar , Ajmer , and Ahmedabad . In

15552-450: The language. Ordu means army in the Turkic languages . In late 18th century, it was known as Zaban-e-Urdu-e-Mualla زبانِ اُرْدُوئے مُعَلّٰی means language of the exalted camp . Earlier it was known as Hindvi, Hindi and Hindustani . Urdu, like Hindi , is a form of Hindustani language . Some linguists have suggested that the earliest forms of Urdu evolved from the medieval (6th to 13th century) Apabhraṃśa register of

15696-427: The last several decades, the number of El Niño events increased, and the number of La Niña events decreased, although observation of ENSO for much longer is needed to detect robust changes. Studies of historical data show the recent El Niño variation is most likely linked to global warming. For example, some results, even after subtracting the positive influence of decadal variation, are shown to be possibly present in

15840-704: The leadership of the Muslim League in Pakistan and the Hindu-dominated Congress Party in India had been educated in English during the British colonial period, and continued to operate in English and send their children to English-medium schools as they continued dominate both countries' post-Partition politics. Although the Anglicized elite in Pakistan has made attempts at Urduisation of education with varying degrees of success, no successful attempts were ever made to Urduise politics,

15984-466: The legal system, the army, or the economy, all of which remained solidly Anglophone. Even the regime of general Zia-ul-Haq (1977–1988), who came from a middle-class Punjabi family and initially fervently supported a rapid and complete Urduisation of Pakistani society (earning him the honorary title of the 'Patron of Urdu' in 1981), failed to make significant achievements, and by 1987 had abandoned most of his efforts in favour of pro-English policies. Since

16128-528: The long term, it is very likely that the precipitation variance related to El Niño–Southern Oscillation will increase". The scientific consensus is also that "it is very likely that rainfall variability related to changes in the strength and spatial extent of ENSO teleconnections will lead to significant changes at regional scale". The El Niño–Southern Oscillation is a single climate phenomenon that periodically fluctuates between three phases: Neutral, La Niña or El Niño. La Niña and El Niño are opposite phases in

16272-404: The main languages of instruction, although the people from differing provinces may have different native languages. Urdu is taught as a compulsory subject up to higher secondary school in both English and Urdu medium school systems, which has produced millions of second-language Urdu speakers among people whose native language is one of the other languages of Pakistan – which in turn has led to

16416-457: The majority population in the city of Karachi , however. Many newspapers are published in Urdu in Pakistan, including the Daily Jang , Nawa-i-Waqt , and Millat . No region in Pakistan uses Urdu as its mother tongue, though it is spoken as the first language of Muslim migrants (known as Muhajirs ) in Pakistan who left India after independence in 1947. Other communities, most notably

16560-403: The most Urdu-speaking states of Uttar Pradesh (c. 8% to 5%) and Bihar (c. 11.5% to 8.5%), even though the number of Muslims in these two states grew in the same period. Although Urdu is still very prominent in early 21st-century Indian pop culture, ranging from Bollywood to social media, knowledge of the Urdu script and the publication of books in Urdu have steadily declined, while policies of

16704-564: The most alive language and moving ahead with times" in India. This phenomenon pertains to the decrease in relative and absolute numbers of native Urdu speakers as opposed to speakers of other languages; declining (advanced) knowledge of Urdu's Perso-Arabic script, Urdu vocabulary and grammar; the role of translation and transliteration of literature from and into Urdu; the shifting cultural image of Urdu and socio-economic status associated with Urdu speakers (which negatively impacts especially their employment opportunities in both countries),

16848-644: The neutral ENSO phase, other climate anomalies/patterns such as the sign of the North Atlantic Oscillation or the Pacific–North American teleconnection pattern exert more influence. El Niño conditions are established when the Walker circulation weakens or reverses and the Hadley circulation strengthens, leading to the development of a band of warm ocean water in the central and east-central equatorial Pacific (approximately between

16992-400: The observed phenomenon of more frequent and stronger El Niño events occurs only in the initial phase of the global warming, and then (e.g., after the lower layers of the ocean get warmer, as well), El Niño will become weaker. It may also be that the stabilizing and destabilizing forces influencing the phenomenon will eventually compensate for each other. The consequences of ENSO in terms of

17136-461: The official languages in northern parts of India in 1837. In colonial Indian Islamic schools, Muslims were taught Persian and Arabic as the languages of Indo-Islamic civilisation ; the British, in order to promote literacy among Indian Muslims and attract them to attend government schools, started to teach Urdu written in the Perso-Arabic script in these governmental educational institutions and after this time, Urdu began to be seen by Indian Muslims as

17280-578: The officially recognised languages in India and also has the status of "additional official language" in the Indian states of Andhra Pradesh , Uttar Pradesh , Bihar , Jharkhand , West Bengal , Telangana and the national capital territory Delhi . Also as one of the five official languages of Jammu and Kashmir . India established the governmental Bureau for the Promotion of Urdu in 1969, although

17424-438: The ongoing Hindi–Urdu controversy and modern cultural association of each language with the two religions has led to fewer Hindus using Urdu. In the 20th century, Indian Muslims gradually began to collectively embrace Urdu (for example, 'post-independence Muslim politics of Bihar saw a mobilisation around the Urdu language as tool of empowerment for minorities especially coming from weaker socio-economic backgrounds' ), but in

17568-652: The oscillation which are deemed to occur when specific ocean and atmospheric conditions are reached or exceeded. An early recorded mention of the term "El Niño" ("The Boy" in Spanish) to refer to climate occurred in 1892, when Captain Camilo Carrillo told the geographical society congress in Lima that Peruvian sailors named the warm south-flowing current "El Niño" because it was most noticeable around Christmas. Although pre-Columbian societies were certainly aware of

17712-415: The other. Conceptual models explaining how ENSO operates generally accept the Bjerknes feedback hypothesis. However, ENSO would perpetually remain in one phase if Bjerknes feedback were the only process occurring. Several theories have been proposed to explain how ENSO can change from one state to the next, despite the positive feedback. These explanations broadly fall under two categories. In one view,

17856-417: The peruvian coast, and increased rainfall and decreased temperatures on its mountainous and jungle regions. Because they don't influence the global climate as much as the other types, these events present lesser and weaker correlations to other significant ENSO features, neither always being triggered by Kelvin waves , nor always being accompanied by proportional Southern Oscillation responses. According to

18000-489: The phenomenon, the indigenous names for it have been lost to history. The capitalized term El Niño refers to the Christ Child , Jesus , because periodic warming in the Pacific near South America is usually noticed around Christmas . Originally, the term El Niño applied to an annual weak warm ocean current that ran southwards along the coast of Peru and Ecuador at about Christmas time. However, over time

18144-518: The position and prestige of English only grew stronger in the meantime. There are over 100 million native speakers of Urdu in India and Pakistan together: there were 50.8 million Urdu speakers in India (4.34% of the total population) as per the 2011 census; and approximately 16 million in Pakistan in 2006. There are several hundred thousand in the United Kingdom, Saudi Arabia, United States, and Bangladesh . However, Hindustani, of which Urdu

18288-558: The preceding Shauraseni language , a Middle Indo-Aryan language that is also the ancestor of other modern Indo-Aryan languages. In the Delhi region of India the native language was Khariboli , whose earliest form is known as Old Hindi (or Hindavi). It belongs to the Western Hindi group of the Central Indo-Aryan languages. The contact of Hindu and Muslim cultures during the period of Islamic conquests in

18432-484: The previous emphasis on Persian. In colonial India, "ordinary Muslims and Hindus alike spoke the same language in the United Provinces in the nineteenth century, namely Hindustani, whether called by that name or whether called Hindi, Urdu, or one of the regional dialects such as Braj or Awadhi ." Elites from Muslim communities, as well as a minority of Hindu elites, such as Munshis of Hindu origin, wrote

18576-483: The region was a part of Afghan Hotak dynasty and stayed a part until 1747 when Ahmed Shah Durrani conquered it and made it a part of Durrani Empire . The first European visited Quetta in 1828, describing it as mud-walled fort surrounded by three hundred mud houses . In 1876, Quetta was occupied by the British and subsequently incorporated into British India . In 1856, British General John Jacob had urged his government to occupy Quetta given its strategic position on

18720-406: The relative frequency of El Niño compared to La Niña events can affect global temperature trends on decadal timescales. There is no sign that there are actual changes in the ENSO physical phenomenon due to climate change. Climate models do not simulate ENSO well enough to make reliable predictions. Future trends in ENSO are uncertain as different models make different predictions. It may be that

18864-646: The same language, Hindustani (or Hindi-Urdu), share a core vocabulary and grammar . Apart from religious associations, the differences are largely restricted to the standard forms : Standard Urdu is conventionally written in the Nastaliq style of the Persian alphabet and relies heavily on Persian and Arabic as a source for technical and literary vocabulary, whereas Standard Hindi is conventionally written in Devanāgarī and draws on Sanskrit . However, both share

19008-513: The status of a province and Quetta became a provincial capital. Quetta has a cold semi-arid climate ( Köppen BSk ) with a significant variation between summer and winter temperatures. Summer starts from late May and goes on until early September with average temperatures ranging from 24–26 °C (75–79 °F). The highest temperature in Quetta is 42 °C (108 °F) which was recorded on 10 July 1998. Autumn starts in mid-September and continues until mid-November with average temperatures in

19152-431: The strength of the trade winds was first identified by Jacob Bjerknes in 1969. Bjerknes also hypothesized that ENSO was a positive feedback system where the associated changes in one component of the climate system (the ocean or atmosphere) tend to reinforce changes in the other. For example, during El Niño, the reduced contrast in ocean temperatures across the Pacific results in weaker trade winds, further reinforcing

19296-583: The style of Urdu spoken on a day-to-day basis in Pakistan is akin to neutral Hindustani that serves as the lingua franca of the northern Indian subcontinent. Since at least 1977, some commentators such as journalist Khushwant Singh have characterised Urdu as a "dying language", though others, such as Indian poet and writer Gulzar (who is popular in both countries and both language communities, but writes only in Urdu (script) and has difficulties reading Devanagari, so he lets others 'transcribe' his work) have disagreed with this assessment and state that Urdu "is

19440-521: The temperature anomalies and precipitation and weather extremes around the world are clearly increasing and associated with climate change . For example, recent scholarship (since about 2019) has found that climate change is increasing the frequency of extreme El Niño events. Previously there was no consensus on whether climate change will have any influence on the strength or duration of El Niño events, as research alternately supported El Niño events becoming stronger and weaker, longer and shorter. Over

19584-618: The term has evolved and now refers to the warm and negative phase of the El Niño–Southern Oscillation (ENSO). The original phrase, El Niño de Navidad , arose centuries ago, when Peruvian fishermen named the weather phenomenon after the newborn Christ. La Niña ("The Girl" in Spanish) is the colder counterpart of El Niño, as part of the broader ENSO climate pattern . In the past, it was also called an anti-El Niño and El Viejo, meaning "the old man." A negative phase exists when atmospheric pressure over Indonesia and

19728-452: The tropical Pacific Ocean. The low-level surface trade winds , which normally blow from east to west along the equator, either weaken or start blowing from the other direction. El Niño phases are known to happen at irregular intervals of two to seven years, and lasts nine months to two years. The average period length is five years. When this warming occurs for seven to nine months, it is classified as El Niño "conditions"; when its duration

19872-425: The two official languages of Pakistan (along with English). It is spoken and understood throughout the country, whereas the state-by-state languages (languages spoken throughout various regions) are the provincial languages , although only 7.57% of Pakistanis speak Urdu as their first language. Its official status has meant that Urdu is understood and spoken widely throughout Pakistan as a second or third language. It

20016-466: The west Pacific is abnormally high and pressure over the east Pacific is abnormally low, during El Niño episodes, and a positive phase is when the opposite occurs during La Niña episodes, and pressure over Indonesia is low and over the west Pacific is high. On average, the temperature of the ocean surface in the tropical East Pacific is roughly 8–10 °C (14–18 °F) cooler than in the tropical West Pacific . The sea surface temperature (SST) of

20160-441: The western and east Pacific. Because the warmer waters of the upper ocean are slightly less dense than the cooler deep ocean, the thicker layer of warmer water in the western Pacific means the thermocline there must be deeper. The difference in weight must be enough to drive any deep water return flow. Consequently, the thermocline is tilted across the tropical Pacific, rising from an average depth of about 140 m (450 ft) in

20304-400: The western frontier. British troops constructed the infrastructure for their establishment as a garrison town. It was reconstructed after the 1935 Quetta earthquake , which razed the city to the ground. The epicentre of the earthquake was close to the city and destroyed most of the city's infrastructure, killing an estimated 40,000 people. After the foundation of Pakistan, Balochistan acquired

Urdu language Urdu ( / ˈ ʊər d uː / ; اُردُو , pronounced [ʊɾduː] , ALA-LC : Urdū ) is a Persianised register of the Hindustani language , an Indo-Aryan language spoken chiefly in South Asia . It is the national language and lingua franca of Pakistan , where it is also an official language alongside English . In India , Urdu

20592-611: Was intentioned as means of unification for Muslims in Northern India and later Pakistan, it adopted a modified Perso-Arabic script. Urdu continued its role in developing a Pakistani identity as the Islamic Republic of Pakistan was established with the intent to construct a homeland for the Muslims of Colonial India. Several languages and dialects spoken throughout the regions of Pakistan produced an imminent need for

20736-555: Was referred to as "Moors", which simply meant Muslim, by European writers. John Ovington wrote in 1689: The language of the Moors is different from that of the ancient original inhabitants of India but is obliged to these Gentiles for its characters. For though the Moors dialect is peculiar to themselves, yet it is destitute of Letters to express it; and therefore, in all their Writings in their Mother Tongue, they borrow their letters from
