Several factors are required for these thunderstorms to develop further, including sea surface temperatures of around 27 °C (81 °F) and low vertical wind shear surrounding the system, atmospheric instability, high humidity in the lower to middle levels of
791-506: A higher intensity. Most tropical cyclones that experience rapid intensification are traversing regions of high ocean heat content rather than lower values. High ocean heat content values can help to offset the oceanic cooling caused by the passage of a tropical cyclone, limiting the effect this cooling has on the storm. Faster-moving systems are able to intensify to higher intensities with lower ocean heat content values. Slower-moving systems require higher values of ocean heat content to achieve

Tropical cyclones A tropical cyclone is a rapidly rotating storm system with a low-pressure center, a closed low-level atmospheric circulation , strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls . Depending on its location and strength,
2034-429: A remnant low-pressure area . Remnant systems may persist for several days before losing their identity. This dissipation mechanism is most common in the eastern North Pacific. Weakening or dissipation can also occur if a storm experiences vertical wind shear which causes the convection and heat engine to move away from the center. This normally ceases the development of a tropical cyclone. In addition, its interaction with
2147-569: A storm. Tropical cyclone scales , such as the Saffir-Simpson hurricane wind scale and Australia's scale (Bureau of Meteorology), only use wind speed for determining the category of a storm. The most intense storm on record is Typhoon Tip in the northwestern Pacific Ocean in 1979, which reached a minimum pressure of 870 hPa (26 inHg ) and maximum sustained wind speeds of 165 kn (85 m/s; 305 km/h; 190 mph). The highest maximum sustained wind speed ever recorded
2260-581: A stronger system. Tropical cyclones are assessed by forecasters according to an array of patterns, including curved banding features , shear, central dense overcast, and eye, to determine the T-number and thus assess the intensity of the storm. The Cooperative Institute for Meteorological Satellite Studies works to develop and improve automated satellite methods, such as the Advanced Dvorak Technique (ADT) and SATCON. The ADT, used by
2373-405: A system has dissipated or lost its tropical characteristics, its remnants could regenerate a tropical cyclone if environmental conditions become favorable. A tropical cyclone can dissipate when it moves over waters significantly cooler than 26.5 °C (79.7 °F). This will deprive the storm of such tropical characteristics as a warm core with thunderstorms near the center, so that it becomes

2599-529: A tropical cyclone are a result of the conservation of angular momentum imparted by the Earth's rotation as air flows inwards toward the axis of rotation. As a result, cyclones rarely form within 5° of the equator . Tropical cyclones are very rare in the South Atlantic (although occasional examples do occur ) due to consistently strong wind shear and a weak Intertropical Convergence Zone . In contrast,

A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean . A typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean and South Pacific, comparable storms are referred to as "tropical cyclones". In modern times, on average around 80 to 90 named tropical cyclones form each year around
2825-461: A tropical cyclone's core has a negative effect on its development and intensity by diminishing atmospheric convection and introducing asymmetries in the storm's structure. Symmetric, strong outflow leads to a faster rate of intensification than observed in other systems by mitigating local wind shear. Weakening outflow is associated with the weakening of rainbands within a tropical cyclone. Tropical cyclones may still intensify, even rapidly, in
2938-401: A tropical cyclone's intensity or the direction it is traveling. Wind-pressure relationships (WPRs) are used as a way to determine the pressure of a storm based on its wind speed. Several different methods and equations have been proposed to calculate WPRs. Tropical cyclones agencies each use their own, fixed WPR, which can result in inaccuracies between agencies that are issuing estimates on
3051-831: A typhoon. This happened in 2014 for Hurricane Genevieve , which became Typhoon Genevieve. Within the Southern Hemisphere, it is either called a hurricane, tropical cyclone or a severe tropical cyclone, depending on if it is located within the South Atlantic, South-West Indian Ocean, Australian region or the South Pacific Ocean. The descriptors for tropical cyclones with wind speeds below 65 kn (120 km/h; 75 mph) vary by tropical cyclone basin and may be further subdivided into categories such as "tropical storm", "cyclonic storm", "tropical depression", or "deep depression". The practice of using given names to identify tropical cyclones dates back to

8475-704: The name was changed to Innisfail State School to reflect the renaming of the town. The original school site is commemorated with a plaque laid on 4 July 1987. The Innisfail Parish within the Roman Catholic Vicariate Apostolic of Cooktown (now the Roman Catholic Diocese of Cairns) was established in 1898. It is now merged with the Mourilyian and South Johnstone parishes. Sacred Heart Catholic School opened on 2 November 1902 with an enrolment of 42 students. It
8588-619: The newspaper. In 2015, the newspaper continues to be published bi-weekly as the Innisfail Advocate by Newscorp . Along with a number of other regional Australian newspapers owned by NewsCorp , the newspaper ceased publication in June 2020. It was deemed "unprofitable" by Newscorp. The Innisfail Advocate will be now covered by the Cairns Post . Historic issues of the newspaper from 1928 to 1954 have been digitised as part of
8701-522: The observed trend of rapid intensification of tropical cyclones in the Atlantic basin. Rapidly intensifying cyclones are hard to forecast and therefore pose additional risk to coastal communities. Warmer air can hold more water vapor: the theoretical maximum water vapor content is given by the Clausius–Clapeyron relation , which yields ≈7% increase in water vapor in the atmosphere per 1 °C (1.8 °F) warming. All models that were assessed in
8814-791: The opening of Innisfail Special School on 29 January 1980. On 7 March 2003 the school was renamed Innisfail Inclusive Education Centre. In 2010 it was amalgamated into the Innisfail State College. Radiant Life Christian College opened on 13 February 1982 and closed on 1 November 1991. In 2001, Los Angeles band Sugar Ray filmed part of their music DVD "Music in High Places" at the Johnstone Crocodile Farm in Innisfail. The Innisfail War Memorial in Jack Fossey Park on Fitzgerald Esplanade
8927-466: The overall frequency of tropical cyclones worldwide, with increased frequency in the North Atlantic and central Pacific, and significant decreases in the southern Indian Ocean and western North Pacific. There has been a poleward expansion of the latitude at which the maximum intensity of tropical cyclones occurs, which may be associated with climate change. In the North Pacific, there may also have been an eastward expansion. Between 1949 and 2016, there
9040-440: The potential of spawning tornadoes . Climate change affects tropical cyclones in several ways. Scientists found that climate change can exacerbate the impact of tropical cyclones by increasing their duration, occurrence, and intensity due to the warming of ocean waters and intensification of the water cycle . Tropical cyclones draw in air from a large area and concentrate the water content of that air into precipitation over
9153-413: The presence of moderate or strong wind shear depending on the evolution and structure of the storm's convection. The size of tropical cyclones plays a role in how quickly they intensify. Smaller tropical cyclones are more prone to rapid intensification than larger ones. The Fujiwhara effect , which involves interaction between two tropical cyclones, can weaken and ultimately result in the dissipation of
9266-444: The release of latent heat from the saturated soil. Orographic lift can cause a significant increase in the intensity of the convection of a tropical cyclone when its eye moves over a mountain, breaking the capped boundary layer that had been restraining it. Jet streams can both enhance and inhibit tropical cyclone intensity by influencing the storm's outflow as well as vertical wind shear. On occasion, tropical cyclones may undergo
9379-492: The same intensity. The passage of a tropical cyclone over the ocean causes the upper layers of the ocean to cool substantially, a process known as upwelling , which can negatively influence subsequent cyclone development. This cooling is primarily caused by wind-driven mixing of cold water from deeper in the ocean with the warm surface waters. This effect results in a negative feedback process that can inhibit further development or lead to weakening. Additional cooling may come in
9492-492: The same system. The ASCAT is a scatterometer used by the MetOp satellites to map the wind field vectors of tropical cyclones. The SMAP uses an L-band radiometer channel to determine the wind speeds of tropical cyclones at the ocean surface, and has been shown to be reliable at higher intensities and under heavy rainfall conditions, unlike scatterometer-based and other radiometer-based instruments. The Dvorak technique plays
9605-503: The school had an enrolment of 165 students with 22 teachers (19 full-time equivalent) and 20 non-teaching staff (13 full-time equivalent). It includes a special education program known as Canecutters Cluster. Good Counsel Primary School is a Catholic primary (Preparatory to Year 6) school for boys and girls at 96 Rankin Street ( 17°31′16″S 146°01′44″E / 17.5212°S 146.0288°E / -17.5212; 146.0288 ( Good Counsel Primary School ) ). In 2018,
9718-404: The school had an enrolment of 279 students with 27 teachers (21 full-time equivalent) and 20 non-teaching staff (13 full-time equivalent). Good Counsel College is a Catholic secondary (7 to 12) school for boys and girls at 66 Owen Street ( 17°31′15″S 146°01′43″E / 17.5207°S 146.0285°E / -17.5207; 146.0285 ( Good Counsel College ) ). In 2018,
9831-495: The school had an enrolment of 371 students with 41 teachers (39 full-time equivalent) and 31 non-teaching staff (24 full-time equivalent). There is no government secondary school within the locality of Innisfail, as the town's government secondary school, Innisfail State College , is located in Innisfail Estate immediately across the river east of the main town centre. The Cassowary Coast Regional Council operates
9944-513: The sea can result in heat being inserted in deeper waters, with potential effects on global climate . Vertical wind shear decreases tropical cyclone predicability, with storms exhibiting wide range of responses in the presence of shear. Wind shear often negatively affects tropical cyclone intensification by displacing moisture and heat from a system's center. Low levels of vertical wind shear are most optimal for strengthening, while stronger wind shear induces weakening. Dry air entraining into
10057-586: The settlement was named Geraldton (officially in July 1883) by Fitzgerald, but on 20 August 1910 it was renamed "Innisfail" to avoid confusion with the town of the same name in Western Australia . It was Margaret-Mary Noone a long time resident of the area who suggested the name Innisfail as a way to honour T.H Fitzgerald's pioneering efforts and Ireland Johnstone River Post Office opened on 1 November 1882 (a receiving office had been open from 1880),
10170-585: The showground. In 1986 many of the showgound's buildings were badly damaged by Cyclone Winifred with further damage sustained during Cyclone Larry in 2006. In 2002 the show introduced a banana packing competition which was very popular. The first Methodist church in Innisfail was completed about October 1913; a Methodist home missionary had been stationed from 1911. The church was at 61 Rankin Street ( 17°31′19″S 146°01′50″E / 17.52198°S 146.03042°E / -17.52198; 146.03042 ( Methodist Church (1913-1918) ) ), opposite
10283-558: The subtropical ridge position, shifts westward across the western Pacific Ocean, which increases the landfall threat to China and much greater intensity in the Philippines . The Atlantic Ocean experiences depressed activity due to increased vertical wind shear across the region during El Niño years. Tropical cyclones are further influenced by the Atlantic Meridional Mode , the Quasi-biennial oscillation and
10396-419: The surface pressure decreases by 2.5 hPa (0.074 inHg) per hour for at least 12 hours or 5 hPa (0.15 inHg) per hour for at least 6 hours. For rapid intensification to occur, several conditions must be in place. Water temperatures must be extremely high, near or above 30 °C (86 °F), and water of this temperature must be sufficiently deep such that waves do not upwell cooler waters to
10509-483: The surface. On the other hand, Tropical Cyclone Heat Potential is one of such non-conventional subsurface oceanographic parameters influencing the cyclone intensity. Wind shear must be low. When wind shear is high, the convection and circulation in the cyclone will be disrupted. Usually, an anticyclone in the upper layers of the troposphere above the storm must be present as well—for extremely low surface pressures to develop, air must be rising very rapidly in
10622-648: The system and its intensity. For example, within the Northern Atlantic and Eastern Pacific basins, a tropical cyclone with wind speeds of over 65 kn (120 km/h; 75 mph) is called a hurricane , while it is called a typhoon or a severe cyclonic storm within the Western Pacific or North Indian oceans. When a hurricane passes west across the International Dateline in the Northern Hemisphere, it becomes known as
10735-723: The town centre. On Sunday 10 November 1935, a Greek Orthodox Church was opened and dedicated to the Assumption of the Blessed Virgin (also known as the Dormition of Our Lady ) by Archbishop Timotheos , the Greek Orthodox Archbishop for Australia and Oceania , in the presence of 300 people. It was the second Greek Orthodox Church to be built in Queensland and the sixth to be built in Australia, but
10848-423: The tropical cyclone year begins on July 1 and runs all year-round encompassing the tropical cyclone seasons, which run from November 1 until the end of April, with peaks in mid-February to early March. Of various modes of variability in the climate system, El Niño–Southern Oscillation has the largest effect on tropical cyclone activity. Most tropical cyclones form on the side of the subtropical ridge closer to
10961-451: The weaker of two tropical cyclones by reducing the organization of the system's convection and imparting horizontal wind shear. Tropical cyclones typically weaken while situated over a landmass because conditions are often unfavorable as a result of the lack of oceanic forcing. The Brown ocean effect can allow a tropical cyclone to maintain or increase its intensity following landfall , in cases where there has been copious rainfall, through
11074-474: The widely reported and dramatic surge in banana prices in Australia. Inflated cost remained until farmers were able to meet demand again in early 2007. After the cyclone the township underwent something of an economic boom that stemmed from an influx of tradespeople and business eager to capitalise upon relatively significant insurance payouts. According to reports local trade had increased some 30 – 40% opposed to expected increases of 10%. On 8 February 2007,
11187-402: The wind speed of Hurricane Helene by 11%, it increased the destruction from it by more than twice. According to World Weather Attribution the influence of climate change on the rainfall of some latest hurricanes can be described as follows: Tropical cyclone intensity is based on wind speeds and pressure. Relationships between winds and pressure are often used in determining the intensity of
11300-702: The world, over half of which develop hurricane-force winds of 65 kn (120 km/h; 75 mph) or more. Tropical cyclones typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water from the ocean surface, which ultimately condenses into clouds and rain when moist air rises and cools to saturation . This energy source differs from that of mid-latitude cyclonic storms , such as nor'easters and European windstorms , which are powered primarily by horizontal temperature contrasts . Tropical cyclones are typically between 100 and 2,000 km (62 and 1,243 mi) in diameter. The strong rotating winds of
11413-795: Was 185 kn (95 m/s; 345 km/h; 215 mph) in Hurricane Patricia in 2015—the most intense cyclone ever recorded in the Western Hemisphere . Warm sea surface temperatures are required for tropical cyclones to form and strengthen. The commonly-accepted minimum temperature range for this to occur is 26–27 °C (79–81 °F), however, multiple studies have proposed a lower minimum of 25.5 °C (77.9 °F). Higher sea surface temperatures result in faster intensification rates and sometimes even rapid intensification . High ocean heat content , also known as Tropical Cyclone Heat Potential , allows storms to achieve
11526-527: Was a slowdown in tropical cyclone translation speeds. It is unclear still to what extent this can be attributed to climate change: climate models do not all show this feature. A 2021 study review article concluded that the geographic range of tropical cyclones will probably expand poleward in response to climate warming of the Hadley circulation . When hurricane winds speed rise by 5%, its destructive power rise by about 50%. Therfore, as climate change increased
11639-582: Was amalgamated with the Innisfail Inclusive Education Centre (a special education facility) and Tropical North Queensland TAFE (Innisfail Campus) to form Innisfail State College using the site of the TAFE campus at Innisfail Estate . Innisfail State High School's website was archived. On 3 July 1970, Innisfail State School introduced a special education program called Opportunity Classes. In 1980 these were replaced by
11752-412: Was dedicated on 16 April 2005; it commemorates those who served in all wars. Innisfail suffered extensive damage in 2006 due to tropical Cyclone Larry , an Australian Category 5 cyclone with over 100mm of rain in the span of three hours. It struck Innisfail at 7am on 20 March 2006, with the eye of the storm passing over the town. Severe structural damage occurred over the entirety of the township,
11865-495: Was described as the largest Catholic church in Queensland outside of its capital Brisbane . On 31 March 1931, a civic reception was held for an international Cricket Team which was followed by a tree planting ceremony where a number of palm trees were planted commemorate the visit to Innisfail by the team. Among the team was cricketer, Sir Donald Bradman. Donald Bradman was part of the international team, led by New South Wales Captain, Alan Kippax in 1931. These palms still stand in
11978-424: Was done to crops and plantations (mainly bananas) which had a serious economic impact on the region. Only one indirect death was record as a result of the cyclone. While Innisfail was always reputed to have a positive sense of community spirit, the aftermath of Tropical Cyclone Larry and the unified cleanup effort acted to promote this spirit through shared suffering. Cyclone Larry was a direct and primary cause of
12091-530: Was held on Friday 11 and Saturday 12 October 1912 in recreation ground (now Callender Park) with exhibits in the Shire Hall and the Oddfellows Hall. In 1935 the show needed more space and the present showgrounds were established (in present-day Goondi Hill ) with purpose-built buildings and a show ring. The show was held annually apart from 1942 and 1942 when, due to World War II , the army was using
12204-408: Was named Nind's Camp after Philip Henry Nind who accompanied the party. Later in 1879, Irishman Thomas Henry Fitzgerald arrived in the area to establish a sugar industry at his Innisfail Estate (now the locality of that name ). He was accompanied by large numbers of Kanaka South Sea Islanders workers accompanied by smaller numbers of Irish labourers. The house built by Fitzgerald and thus
12317-651: Was operated by the Sisters of the Good Samaritan . It was renamed Good Counsel Catholic Primary School in 1975. When the Sisters were no longer able to lead the school, it was briefly led by the Marist Brothers until the first lay principal was appointed in 1982. The Sisters withdrew from teaching in the school in 1990. In 1906, Patrick Leahy established the Johnstone River Advocate newspaper, with
12430-479: Was popular at that time, many of the new buildings were built in the Art Deco style. As a result, Innisfail is now considered one of the best Australian towns for Art Deco and Streamline Moderne architecture. The 1920s and 1930s saw the beginning of a major period of settlement by Italian immigrants and noteworthy populations from Greece and Malta . Later in this period populations from Yugoslavia , India and
12543-529: Was published daily and in May 1941 was renamed the Evening Advocate . In 1973 a massive increase in the cost of telex messages used to circulate syndicated news made the newspaper financially unviable and Groom threatened to close the newspaper in September 1973. However he was persuaded to continue to publish the newspaper and from October 1973 it was published only three times a week without telexed news content. Groom retired in January 1978, selling
12656-434: Was renamed Geraldton two months later and Innisfail in 1910. The settlers who moved into this region from 1889 were exceptionally diverse. The first influential group were Anglo-Celtic, but they were outnumbered by "Kanaka " South Sea Islanders. Aboriginal and Torres Strait workers, Chinese miners who developed the banana industry and retail businesses. French merchants, and German timber and sugar producers. In May 1885,
12769-585: Was revived in the latter part of World War II for the Western Pacific. Formal naming schemes have subsequently been introduced for the North and South Atlantic, Eastern, Central, Western and Southern Pacific basins as well as the Australian region and Indian Ocean. At present, tropical cyclones are officially named by one of twelve meteorological services and retain their names throughout their lifetimes to provide ease of communication between forecasters and
