28-521: The city has a main square with the Catédral de Sechura , built in the 18th century in the Spanish colonial style. Because of the desert surrounding the city, the church has sometimes been called the Catédral de Arena (Sand Cathedral). Sechura has a hot desert climate ( Köppen : BWh ) characterized by high temperatures throughout the year and extremely low precipitation. December through May marks

56-462: A tropical savanna climate or a humid subtropical climate . These climates tend to have hot, or sometimes extremely hot, summers and warm to cool winters, with some to minimal precipitation. Hot semi-arid climates are most commonly found around the fringes of subtropical deserts. Hot semi-arid climates are most commonly found in Africa , Australia , and South Asia . In Australia, a large portion of

84-773: A few instances), dry summers, though summers are not typically as hot as hot desert climates. Unlike hot desert climates, cold desert climates tend to feature cold, dry winters. Snow tends to be rare in regions with this climate. The Gobi Desert in northern China and Mongolia is one example of a cold desert. Though hot in the summer, it shares the freezing winters of the rest of Inner Asia . Summers in South America's Atacama Desert are mild, with only slight temperature variations between seasons. Cold desert climates are typically found at higher altitudes than hot desert climates and are usually drier than hot desert climates. Cold desert climates are typically located in temperate zones in

112-434: A location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): If the area's annual precipitation in millimeters is less than the threshold but more than half or 50% the threshold, it is classified as a BS (steppe, semi-desert, or semi-arid climate). Furthermore, to delineate hot semi-arid climates from cold semi-arid climates,

140-409: A mean annual temperature of 18 °C (64.4 °F) is used as an isotherm. A location with a BS -type climate is classified as hot semi-arid ( BSh ) if its mean temperature is above this isotherm, and cold semi-arid ( BSk ) if not. Hot semi-arid climates (type "BSh") tend to be located from the high teens to mid-30s latitudes of the tropics and subtropics , typically in proximity to regions with

168-795: Is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration , but not as low as a desert climate . There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes . A more precise definition is given by the Köppen climate classification , which treats steppe climates ( BSh and BSk ) as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as they usually cannot support forests. To determine if

196-402: Is a stub . You can help Misplaced Pages by expanding it . Hot desert climate The desert climate or arid climate (in the Köppen climate classification BWh and BWk ) is a dry climate sub-type in which there is a severe excess of evaporation over precipitation . The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating

224-566: Is determined. The precipitation threshold (in millimetres) involves first multiplying the average annual temperature in °C by 20, then adding 280 if 70% or more of the total precipitation is in the high-sun summer half of the year (April through September in the Northern Hemisphere , or October through March in the Southern), or 140 if 30–70% of the total precipitation is received during the applicable period, or 0 if less than 30% of

252-550: Is seen in sections of Africa and Arabia . During colder periods of the year, night-time temperatures can drop to freezing or below due to the exceptional radiation loss under the clear skies. However, temperatures rarely drop far below freezing under the hot subtype. Hot desert climates can be found in the deserts of North Africa such as the wide Sahara Desert , the Libyan Desert or the Nubian Desert ; deserts of

280-403: Is used as an isotherm so that a location with a BW type climate with the appropriate temperature above this isotherm is classified as "hot arid subtype" ( BW h ), and a location with the appropriate temperature below the isotherm is classified as "cold arid subtype" ( BW k ). Most desert/arid climates receive between 25 and 200 mm (1 and 8 in) of rainfall annually, although some of

308-755: The ABC Islands , the rain shadows of Hispaniola 's mountain ranges in the Dominican Republic and Haiti , parts of the Southwestern United States including California's Central Valley , and sections of South America such as the sertão , the Gran Chaco , and the poleward side of the arid deserts, where they typically feature a Mediterranean precipitation pattern, with generally rainless summers and wetter winters. They are also found in few areas of Europe surrounding

336-953: The Horn of Africa such as the Danakil Desert or the Grand Bara Desert ; deserts of Southern Africa such as the Namib Desert or the Kalahari Desert ; deserts of West Asia such as the Arabian Desert , or the Syrian Desert ; deserts of South Asia such as Dasht-e Lut and Dasht-e Kavir of Iran or the Thar Desert of India and Pakistan; deserts of the United States and Mexico such as

364-642: The Indian Subcontinent , southwestern Africa, interior Australia, the Southwestern United States , northern Mexico , sections of southeastern Spain , the coast of Peru , and Chile . This makes hot deserts present in every continent except Antarctica. At the time of high sun (summer), scorching, desiccating heat prevails. Hot-month average temperatures are normally between 29 and 35 °C (84 and 95 °F), and midday readings of 43–46 °C (109–115 °F) are common. The world's absolute heat records, over 50 °C (122 °F), are generally in

392-599: The Mediterranean Basin . In Europe, BSh climates are predominantly found in southeastern Spain . It can also be found primarily in parts of south Greece but also in marginal areas of Thessaloniki and Chalkidiki in north Greece , most of Formentera , marginal areas of Ibiza and marginal areas of Italy in Sicily , Sardinia and Lampedusa . Cold semi-arid climates (type "BSk") tend to be located in elevated portions of temperate zones generally from

420-804: The Mojave Desert , the Sonoran Desert or the Chihuahuan Desert ; deserts of Australia such as the Simpson Desert or the Great Victoria Desert and many other regions. In Europe , the hot desert climate can only be found on southeastern coast of Spain as well as small inland parts of southeastern, especially parts of the Tabernas Desert . Hot deserts are lands of extremes: most of them are among

448-523: The Outback surrounding the central desert regions lies within the hot semi-arid climate region. In South Asia, both India and parts of Pakistan experience the seasonal effects of monsoons and feature short but well-defined wet seasons , but are not sufficiently wet overall to qualify as either a tropical savanna or a humid subtropical climate. Hot semi-arid climates can be also found in parts of North America , such as most of northern Mexico ,

476-534: The Sahara Desert such as Kufra , Libya , record an even drier 0.86 mm (0.034 in) of rainfall annually. The official weather station in Death Valley , United States reports 60 mm (2.4 in) annually, but in 40 months between 1931 and 1934 a total of just 16 mm (0.63 in) of rainfall was measured. To determine whether a location has an arid climate, the precipitation threshold

504-652: The 30s and 40s latitudes, usually in the leeward rain shadow of high mountains, restricting precipitation from the westerly winds. An example of this is the Patagonian Desert in Argentina, bounded by the Andes ranges to its west. In the case of Central Asia, mountains restrict precipitation from the eastern monsoon . The Kyzyl Kum , Taklamakan and Katpana Desert deserts of Central Asia are other significant examples of BWk climates. The Ladakh region and

532-792: The Arctic and Antarctic regions receive very little precipitation during the year owing to the cold, dry air freezing most precipitation. Polar desert climates have desert-like features that occur in cold desert climates, including intermittent streams, hypersaline lakes, and extremely barren terrain in unglaciated areas such as the McMurdo Dry Valleys of Antarctica. These areas are generally classified as having polar climates because they have average summer temperatures below 10 °C (50 °F) even if they have some characteristics of extreme non-polar deserts. Semi-arid A semi-arid climate , semi-desert climate , or steppe climate

560-504: The already little rainfall they receive. Covering 14.2% of Earth's land area, hot deserts are the second-most common type of climate on Earth after the Polar climate . There are two variations of a desert climate according to the Köppen climate classification : a hot desert climate ( BWh ), and a cold desert climate ( BWk ). To delineate "hot desert climates" from "cold desert climates", a mean annual temperature of 18 °C (64.4 °F)

588-994: The city of Leh in the Great Himalayas in India also have a cold desert climate. In North America, the cold desert climate occurs in the drier parts of the Great Basin Desert and the Bighorn Basin in Big Horn and Washakie County in Wyoming . The Hautes Plaines , located in the northeastern section of Morocco and in Algeria , is another prominent example of a cold desert climate. In Europe , this climate only occurs in some inland parts of southeastern Spain, such as in Lorca . Polar climate desert areas in

616-599: The hot deserts, where the heat potential can be the highest on the planet. This includes the record of 56.7 °C (134.1 °F) in Death Valley , which is currently considered the highest temperature recorded on Earth . Some deserts in the tropics consistently experience very high temperatures all year long, even during wintertime. These locations feature some of the highest annual average temperatures recorded on Earth, exceeding 30 °C (86 °F), up to nearly 35 °C (95 °F) in Dallol, Ethiopia . This last feature

644-673: The hotter part of the year. February, the hottest month, averages daily highs of 33 °C (91 °F) and daily lows of 23 °C (73 °F). In addition, the majority of Sechura's 80 millimetres (3.1 in) of yearly precipitation falls in between January and March. June to November marks the cooler half of the year, with warm temperatures and negligible rainfall. August, the coolest month, averages daily highs of 26 °C (79 °F) and daily lows of 17 °C (63 °F). 5°33′27.30″S 80°49′20.28″W  /  5.5575833°S 80.8223000°W  / -5.5575833; -80.8223000 This Piura Region geography article

672-444: The hottest, the driest, and the sunniest places on Earth because of nearly constant high pressure; the almost permanent removal of low-pressure systems, dynamic fronts, and atmospheric disturbances; sinking air motion; dry atmosphere near the surface and aloft; the exacerbated exposure to the sun where solar angles are always high makes this desert inhospitable to most species. Cold desert climates ( BWk ) usually feature hot (or warm in

700-525: The mid-30s to low 50s latitudes, typically bordering a humid continental climate or a Mediterranean climate . They are also typically found in continental interiors some distance from large bodies of water. Cold semi-arid climates usually feature warm to hot dry summers, though their summers are typically not quite as hot as those of hot semi-arid climates. Unlike hot semi-arid climates, areas with cold semi-arid climates tend to have cold and possibly freezing winters. These areas usually see some snowfall during

728-549: The most consistently hot areas of Central Australia , the Sahel and Guajira Peninsula can be, due to extreme potential evapotranspiration , classed as arid with the annual rainfall as high as 430 millimetres or 17 inches. Although no part of Earth is known for certain to be rainless, in the Atacama Desert of northern Chile, the average annual rainfall over 17 years was only 5 millimetres (0.20 in). Some locations in

756-650: The total precipitation is so received there. If the area's annual precipitation is less than half the threshold (50%), it is classified as a BW (desert climate), while 50–100% of the threshold results in a semi-arid climate. Hot desert climates ( BWh ) are typically found under the subtropical ridge in the lower middle latitudes or the subtropics , often between 20° and 33° north and south latitudes. In these locations, stable descending air and high pressure aloft clear clouds and create hot, arid conditions with intense sunshine. Hot desert climates are found across vast areas of North Africa , West Asia , northwestern parts of

784-796: The winter, though snowfall is much lower than at locations at similar latitudes with more humid climates. Areas featuring cold semi-arid climates tend to have higher elevations than areas with hot semi-arid climates, and tend to feature major temperature swings between day and night, sometimes by as much as 20 °C (36 °F) or more. These large diurnal temperature variations are seldom seen in hot semi-arid climates. Cold semi-arid climates at higher latitudes tend to have dry winters and wetter summers, while cold semi-arid climates at lower latitudes tend to have precipitation patterns more akin to Mediterranean climates , with dry summers, relatively wet winters, and even wetter springs and autumns. Cold semi-arid climates are most commonly found in central Asia and
