By this time, however, the system was quickly approaching the Australian coast, so the time available for further intensification was very limited. [87][88] By the following day, the tropical low became slow-moving over the southeastern Kimberley region, during which time a minimum atmospheric pressure of 992.5 hPa (29.31 inHg) was recorded at Halls Creek. [51] Environmental conditions around the system were conducive for intensification, with low vertical wind shear, good upper-level outflow and sea surface temperatures near 30 °C (86 °F). [89][90], Tropical Low 03U generated strong winds in the Kimberley region and on nearby islands for several days while located nearby. [32][33] By 12:00 UTC on 10 December, the system had begun to accelerate towards the southeast, moving into an environment more favourable for intensification. Lord Howe Island lies within the region, but Norfolk Island lies east of the region, although the bureau continues to monitor tropical cyclones when they are a threat to the external territory. Within the North Atlantic Ocean, tropical or subtropical cyclones are named by the National Hurricane Center (NHC/RSMC Miami) when they are judged to have intensified into a tropical storm with winds of at least 34 kn (39 mph; 63 km/h). Category:Australian region cyclones | Military Wiki | Fandom. [18] At its peak intensity in the Australian region, the BOM estimated the system's minimum atmospheric pressure as 1005 hPa (29.68 inHg) on 25 November. Additionally, it is also the deadliest tropical cyclone season recorded in the Australian region, with Cyclone Flores killing an estimated 1,650 people alone, making Flores the single-deadliest tropical cyclone recorded in the entire Southern Hemisphere. ; Please keep off-topic and political discussion to a minimum, and respect the guidelines listed to the right. There is a history of tropical cyclones affecting northeastern Australia for over 5000 years; however, Clement Lindley Wragge was the first person to monitor and name them. Despite tracking over land, the tropical low showed signs of organisation, with the generally favourable atmospheric conditions allowing the development of formative convective banding in the system's southern semicircle. [11] Consequently, the tropical low was expected to have only a low chance of developing into a tropical cyclone prior to moving westwards out of the Australian region later in the week. [59] Maximum wind gust speeds recorded on the mainland included 67 km/h (42 mph) at Port Hedland;[60] 65 km/h (40 mph) in Warburton;[61] 63 km/h (39 mph) at Lombadina;[62] 61 km/h (38 mph) at Giles and Telfer,[63][64] 59 km/h (37 mph) at Christmas Creek;[65] 56 km/h (35 mph) at Broome, Curtin, Derby and Barimunya,[66][67][68][69] 54 km/h (34 mph) at Karratha and Marble Bar;[70][71] 52 km/h (32 mph) at Roebourne;[72] and 50 km/h (31 mph) at Mandora. Die Australische Zyklonsaison 2013–2014 begann offiziell am 1.November 2013 und endete am 30. Juni 2014. [6][7] On 24 November, the Bureau of Meteorology (BOM) reported that a tropical low had developed within a trough in the far northwestern corner of the Australian region, located approximately 860 km (535 mi) northwest of the Cocos Islands. [2], In the early history of tropical cyclones in the Australian region, the only evidence of a storm was based on ship reports and observations from land. [37][38], Tropical Low 02U made landfall between Port Hedland and Whim Creek on the Pilbara coastline just after 03:00 UTC on 11 December. Upload media Wikipedia: Follows: 2017–18 Australian region cyclone season; Authority control Q55389060. [24] A total of 23.6 mm (0.93 in) of rainfall was also recorded on 24–28 November. [12] Despite this, the system remained mostly disorganised in the marginal environment, with an elongated low-level circulation centre. The season officially began on 1 November 2020 and will end on 30 April 2021, however, a tropical cyclone could form at any time between 1 July 2020 and 30 June 2021 and would count towards the season total. Near normal activity during the season was expected for Papua New Guinea and the Solomon Islands, while an elevated level of activity was expected in the Coral Sea and the northern Tasman Sea, especially during the late season. Australien (amtlicher deutscher Name; englisch Commonwealth of Australia, deutsch veraltet Australischer Bund) ist ein Staat auf der Südhalbkugel der Erde, der die gesamte Landmasse des australischen Kontinents, die ihr südlich vorgelagerte Insel Tasmanien, die subantarktische Macquarieinsel mit ihren Nebeninseln und als Außengebiete die pazifische Norfolkinsel, die … [citation needed], The Bureau of Meteorology defines four regions within the Australian region which are used when the bureau issues tropical cyclone seasonal outlooks every year. [40][41] Ten-minute sustained winds also reached 63 km/h (39 mph) on Legendre Island at 00:00 UTC. [74][75][76][77], During mid December, favourable conditions from a pulse of the Madden–Julian Oscillation (MJO) located over the eastern Maritime Continent contributed to the re-formation of the monsoon trough over northern Australia. [4] The sub-region covers waters off Western Australia north of Shark Bay, and extends westward to Christmas Island. By late on 7 December, infrared satellite imagery indicated an improvement in the structure of the low, with the system displaying an increase in flaring deep convection, accompanied by rotation evident in the lower troposphere. The system was last mentioned as a tropical low by the BOM on 11 December while located in central Western Australia. [43][44] Despite tracking over land, the BOM indicated that sustained winds to gale force, accompanied by gusts of up to 100 km/h (60 mph), could still occur near the centre of the system, particularly on the eastern side. [13] On 29 November, the tropical low began to be steered slowly towards the west-northwest on the northern side of the subtropical high pressure belt. Australian region tropical cyclone seasons The 2020–21 Australian region cyclone season was a near average season that saw the formation of 11 tropical cyclones, five of which became severe tropical cyclones. The 2022–23 Australian Region Cyclone Season is the period of the year when most tropical cyclones form within the Southern Indian Ocean and Pacific Oceans between 90°E and 160°E. [26][27] The system was assigned the official identifier code 02U upon formation. This is the forum page for the 2019-20 Australian Region cyclone season.. 1973–74 Australian region cyclone season; Season summary map. Environmental conditions remained only marginally favourable for development, however, and the system's deep convection became displaced to the southwest of the centre due to northeasterly vertical wind shear, leaving the low-level circulation centre fully exposed. Should a tropical depression reach tropical cyclone strength within TCWC Jakarta's area of responsibility, it will be assigned the next name from the following list:[96][97]. The sub-region averages five tropical cyclones in a season, and the bureau assesses the sub-region to have a moderate level of accuracy when forecasting tropical cyclone activity. The region averages four tropical cyclones in a season, and the bureau assesses the region to have a low level of accuracy when forecasting tropical cyclone activity. Read the detailed post cyclone reports for Australian cyclones dating back to 1970. The next 12 names on the naming list are listed below: The tropical cyclone warning centre in Jakarta monitors tropical cyclones from the Equator to 11°S, between the longitudes 90°E and 145°E. The 2020-21 Australian region cyclone season was a slightly below-average season, with nine tropical cyclones, six of which intensified further into severe tropical cyclones. The outlook called for a reduced level of tropical cyclone activity in the early season, from November to January, but an increased level of activity in the late season, from February to April. [37] Sustained gale-force winds were observed at Bedout Island and Port Hedland around the time of landfall, peaking at 70 km/h (43 mph) at both locations. [34] The tropical low continued rapidly inland across Western Australia over the next day, accelerating to about 50 km/h (30 mph) soon after landfall. Popular pages. [49] Owing to the increase in organisation, the Bureau of Meteorology (BOM) classified the system as a tropical low by 21:00 UTC,[50] when it was located approximately 330 km (205 mi) northwest of Broome. Tropical cyclones that develop between the Equator and 11°S, between the longitudes 151°E and 160°E, are assigned names by the tropical cyclone warning centre in Port Moresby, Papua New Guinea. The 2020–21 Australian region cyclone season is the period of the year when tropical cyclones form in the Southern Indian Ocean and Pacific Oceans between 90°E and 160°E. The regional tropical cyclone operational plan defines a "tropical cyclone year" separately from a "tropical cyclone season"; the "tropical cyclone year" began on 1 July 1988 and ended on 30 June 1989. After the onset of satellite imagery, the Dvorak technique was used to estimate storm's intensities and locations. [4] The region covers the Timor Sea, the Banda Sea, the Arafura Sea and the Gulf of Carpentaria. [53] The JTWC issued a tropical cyclone formation alert for the tropical low at 21:30 UTC, noting the presence of convective rainbands wrapping into the system, as well as persistent deep convection over the low-level circulation centre. [3], The Australian region is currently defined as being between 90°E and 160°E and is monitored by five different warning centres during the season that runs from 1 November to 30 April. [86] After reaching the Dampier Peninsula on 20 December, the system turned sharply to the east and began tracking further inland. [94] Upon entering the region, the system was classified as a tropical low by the Bureau of Meteorology (BOM), and had an estimated central atmospheric pressure of 1006 hPa (29.71 inHg). The system then weakened and dissipated well east of Madagascar. [55][56], The tropical low and associated thunderstorms generated strong winds in coastal and inland areas of the Kimberley and Pilbara regions as it tracked through the area, including sustained winds near gale force at several offshore sites. An Australian region tropical cyclone is a non-frontal, low pressure system that has developed, within an environment of warm sea surface temperatures and little vertical wind shear aloft in either the Southern Indian Ocean or the South Pacific Ocean.

Australian east coast lows (known locally as east coast lows and sometimes as east coast cyclones) are extratropical cyclones, the most intense of these systems have many of the characteristics of subtropical cyclones. With an average of 10 cyclones per year developing amongst areas such as Exmouth and Broome in the west, and far north Queensland in the east, cyclone season can be pretty daunting. The outlook took into account the ENSO neutral conditions that had been observed across the Pacific and analogue se… [6][7] The presence of the MJO brought an increase in tropical moisture to the atmospheric environment, as well as aiding the formation of Tropical Cyclone Alicia in the South-West Indian Ocean region in mid November. To have your suggestion considered please submit a written request (including pronunciation of the name) to: Manager Tropical Cyclone and Extreme Weather Bureau of Meteorology GPO Box 1289 Melbourne VIC 3001. The BOM predicted that the La Niña pattern will persist into early 2021, and waters north of Australia and the Southwestern Pacific Ocean will be warmer than average in the coming three months. The region also covers waters off Indonesia that include the main islands of Java, Bali, Lombok, Sumbawa, Sumba, Flores and the western half of Timor. [57] Sustained winds also reached 56 km/h (35 mph) at Bedout Island on 8 December, with a peak gust of 67 km/h (42 mph),[58] and Rowley Shoals recorded maximum sustained winds of 52 km/h (32 mph) and gusts to 65 km/h (40 mph). This was the first Australian tropical cyclone season since 2014–15 to feature at least six severe tropical cyclones. [17] The system later intensified into Severe Tropical Storm Bongoyo in the South-West Indian Ocean cyclone region on 7 December. The United States Joint Typhoon Warning Center (JTWC) and other national meteorological services including Météo-France will also monitor the basin during the season. [5], During mid to late November 2020, a moderate strength pulse of the Madden–Julian Oscillation (MJO) tracked eastwards across the equatorial Indian Ocean towards the Maritime Continent and Australian longitudes. [26] Initially located in an unfavourable environment for intensification, the tropical low began to encounter somewhat improved conditions as it tracked towards the southeast. [80][81] The system soon assumed a southwestward track towards the Kimberley region. [20], Tropical Low 01U made its closest approach to the Cocos Islands on 27–28 November, passing a little more than 500 km (310 mi) to the west. Below average sea surface temperatures in the eastern tropical Pacific Ocean and atmospheric conditions indicated a La Niña pattern, and it was declared that a La Niña had emerged on 29 September 2020. The system crossed over the Cape York Peninsula and moved into the Gulf of Carpentaria, whereupon it gradually organized due to warm waters and … [47][48] Initially lacking organised deep convection, the system proceeded to track in a generally southwards direction towards the Kimberley region of Western Australia. [54] The system moved inland over the following days, tracking in a generally south-southeasterly direction. For much of its duration, the system moved westward due to a ridge to the south. [85], The system continued towards the southwest over the ensuing hours, paralleling the coast of Western Australia. The region averages seven tropical cyclones in a season, and the bureau assesses the region to have a low level of accuracy when forecasting tropical cyclone activity. It formed from the monsoon trough on 12 February in the Coral Sea. The season officially began on 1 November 2020 and will end on 30 April 2021, however, a tropical cyclone could form at any time between 1 July 2020 and 30 June 2021 and would count towards the season total. They attributed the strong winds on the eastern side of the system to a combination of enhanced northwesterly monsoonal flow and the system's fast translational velocity, rather than the low having intensified into a tropical cyclone. Cyclone Marcia intensified from a category 2 to a category 5 just before crossing the Queensland coast north of Rockhampton in February 2015. The season was the first to feature multiple cyclones of Category 5 intensity since 2013-14, with Imogen, Seroja and Marian all reaching this intensity. [1][2] The bureau also advised that cyclone kits include a supply of face masks and hand sanitisers, owing to the concurrent COVID-19 pandemic. [5] The region also covers waters off Papua New Guinea and western parts of the Solomon Islands. Pre-empting dangerous coastal erosion, conservation volunteers worked hard to relocate the nests of loggerhead turtles higher up the beache… Tropical cyclone activity in the Australian region has large variability from year to year, due to the influence of naturally occurring climate drivers, such as ENSO. [10] The Joint Typhoon Warning Center (JTWC) assessed environmental conditions as being only marginally conducive for tropical cyclogenesis, with good poleward outflow and sea surface temperatures near 30 °C (86 °F) being offset by the effects of moderate vertical wind shear. [80] Environmental conditions were favourable for tropical cyclogenesis, with low to moderate vertical wind shear, good upper-level outflow and very warm sea surface temperatures nearing 31 °C (88 °F). The season officially ran from November 1, 2022 to April 30, 2023, however a tropical cyclone could form at any time between July 1, 2022 and June 30, 2023 and would count towards the season total. The 1988–89 Australian region cyclone season was a slightly above average tropical cyclone season. Ahead of the cyclone season, the Australian Bureau of Meteorology (BoM), the New Zealand National Institute of Water and Atmospheric Research (NIWA)and various other Pacific Meteorological services, all contributed towards the Island Climate Update tropical cyclone outlook that was released during October 2019.
