2010–11 Australian region cyclone season

The Australian cyclone 2010-2011 season officially began on 1 November 2010 and lasted until 30 April 2011. Operating plan of the World Meteorological Organization looks for the waters in the southern hemisphere in addition a "tropical cyclone year " before. This began on 1 July 2010 and will end on 30 June 2011.

Part of the Australian cyclone season storms that form south of the equator, between the 90th and 160th degree of east longitude. This includes Australia, Papua New Guinea, the western part of the Solomon Islands, East Timor and the southern areas of Indonesia. Tropical cyclones in this area are from Tropical Cyclone Warning Centres five ( TCWCs ) monitors: the Bureau of Meteorology in Perth, Darwin and Brisbane in Australia; the TCWC Djakarta in Indonesia and the TCWC Port Moresby in Papua New Guinea.

The Joint Typhoon Warning Center gives this region from unofficial warnings that are intended for U.S. institutions. The extension " S" is used when the storm is west of 135 ° E, and a "P ", if this is happening east of this line.

Season forecasts

Bureau of Meteorology

Since the Australian cyclone season 2009-2010 is the National Climate Center (NCC ) of the Bureau of Meteorology before the cyclone season a forecast from which the tropical cyclone activity in the whole basin is predicted between 90 ° E and 160 ° E. For the first time this season, said the NCC not only the total number of cyclones in the waters around Australia ahead of the tropical cyclone year from July 2010 to June 2011, but divided the forecast in the regions of West, Northwest [ nb 1], North and East. For the year 2010-2011 the BoM cyclone was assumed that due to the La Niña effect, the cyclone activity could employ about two weeks earlier than is usual.

For the cyclone year 2010/2011, the NCC was assumed that it could come to the most active cyclone season since the cyclone season 1983-1984 in the Australian region, with 20-22 tropical cyclones that form in the region or migrate into it, compared to the average of twelve tropical cyclones. For the West, the area of ​​responsibility of the Bureau of Meteorology, the NCC predicts the formation of eleven to twelve tropical cyclones, in contrast to the average of seven. The NCC is for the Northwest assume that form seven to eight cyclones or pull through, and in this part of the basin, the average is six. For the northern region, the NCC stated that it expects five cyclones in this area. The NCC noted, however, that the skills of meteorologists are rather small in terms of prediction in this area. For the eastern part of the waters around Australia, the NCC announced that it expects six to seven cyclones, and in this area the average is four.

City University of Hong Kong

Since the cyclone season 2009-2010 published by the Guy Carpenter Asia- Pacific Climate Impact Centre ( GCACIC ) at the City University of Hong Kong ( CityUHK ) seasonal forecasts for the coming cyclone season. This forecast of the cyclone activity for the region as a whole and for the western part of the basin between 90 ° E and 135 ° E created separately and published in November.

Storms

Tropical Cyclone Anggrek

On 28 October the TCWCs the Bureau of Meteorology reported in Perth and Darwin, that the responsibility of the TCWCs in Jakarta, has about 650 kilometers west of Jakarta and about 530 km north of the Cocos Islands formed a westward pulling tropical depression. The system then turned to a southeast trajectory and intensified during the following days continuously. Early on October 31, noted the TCWC Djakarta that the system has reached the intensity of a tropical cyclone and the storm gave the name Anggrek. Anggrek migrated southwards and reached the area of ​​responsibility of the TCWCs in Perth. Meanwhile, it had intensified into a Category 2 cyclone according to the scale of the Bureau of Meteorology. The cyclone moved east on November 2 at the Cocos Islands by - in the meantime for the highest warning level was proclaimed and where heavy rainfall and gusty winds were recorded during the passage of Anggrek - and weakened due to stronger and stronger wind shear again. The cyclone then hit a curve to the right towards the southwest and weakened during further. Finally, the remnant low drifted westward and continued to lose intensity. On November 4, the TCWC in Perth reported the weakening into a tropical low and gave the last warning.

Tropical Cyclone Abele

On November 29 was formed west of the 90th degree of longitude, a tropical depression, which has been classified by the TCWC Perth as a tropical depression 02U. The system first moved southward and intensified in the southwest Indian Ocean tropical cyclone to, but then went in a south-easterly direction of pull, and thus came on 3 December in the area of ​​responsibility of TCWCs in Perth. The RSMC La Reunion spent his last warning to Abele, when the cyclone had already crossed 90 ° E Längein southeast. According to this warning Abele had the intensity of a category 2 cyclone on the Australian scale. The Bureau of Meteorology took a few hours later, the responsibility for Abele and classified the system back to a Category 1 cyclone. On December 4, the storm turned to a south- southeasterly direction of tension and weakened to a tropical depression, so that the TCWC in Perth issued the final warning to Abele. The remnant low of the former cyclone moved two days slowly in a southeasterly direction and lost from strength to strength, and dissipated on December 6 completely.

Tropical Depression 03U

On December 15, formed off the coast of Western Australia, approximately 500 km north- west of Exmouth a monsoon low that drifted slowly Südösten. Gusts and heavy rain reached areas far from the center of the low, which crossed the coast line on December 18, near Coral Bay. Shortly after landfall the system swung sharply to the southwest, reaching on 19 December the waters of the Indian ocean that surrounds west of Carnarvon. The system then moved away from the coast and broke up late around 500 kilometers west of Geraldton on 20 December on.

At the Gascoyne River and its watershed was extensively rain, which caused one of the worst floods of the river in the recorded history between the 16th and 19th of December. The tropical rainfall had also to other river basins in the region, including Wooramel River, Murchison River, River Lyndon, Minilya River and Ashburton River. For the period from December 16 to 20, some weather stations reported a rainfall of up to 300 mm, which corresponds to the long-term average annual rainfall in the region. The highest rainfall in 24 hours reported the station at Carnarvon Airport on 17 December with 207.8 mm, which is the highest measured there in one day rainfall since records began in Carnarvon in 1883. The previous record high of 119.4 mm was measured on 24 March 1923.

According to preliminary estimates, the damage totaled about 100 million Australian dollars (about 100.4 million U.S. dollars ) and at least 2,000 head of cattle were drowned by the flood.

Tropical Depression 04U

Tropical cyclone Tasha

Tasha was a relatively weak cyclone, but the large amounts of rainfall led to Queensland. On December 20, formed in the northern Coral Sea, southeast of Papua New Guinea, a tropical depression. The system moved slowly in a roughly southwesterly direction and finally came on 24 December in a favorable for the development of a tropical storm environment. Within hours, the system gained strength enough to be classified by the TCWC Brisbane as a Category 1 cyclone. Only a few hours later came the center of the cyclone near Gordonvale, between Cairns and Innisfail, over the tropical north of the state. About Land of the cyclone was soon downgraded to a tropical depression before it disbanded on 25 December.

On the south side of the cyclone rainfall were recorded, which were between 150 and 250 mm. Thus Tasha drenched the earth, and in cooperation with prolonged monsoon rains in the days that followed, emerged the strongest floods in decades.

Tropical Depression 06U

About the Top End of the Northern Territory at the end of December formed a tropical depression, which migrated continuously from west to south-westerly direction to Western Australia. The TCWC Perth began on 30 December, when the system was drawn across the Kimberley region and north of Broome reached the Indian Ocean. About the warm waters of the ocean to 06U intensified slowly, but dissolved on January 4, so that the TCWC in Perth published the final warning to the system on the day.

Tropical Depression 07U

Tropical Depression 08U

Tropical Cyclone Vince

On 10 January, some 700 km north-northwest formed off the coast of Onslow Western Australia, a tropical depression that moved westward first. It intensified into a cyclone two days later and changed on January 12, abruptly the direction. During the next days the system from TCWC in Perth the name Vince got in an east - southeasterly direction moved. The predictions were initially assume that Vince would intensify to a category 2 cyclone, but on 14 January lost the cyclone of organization un weakened to a tropical depression off.

Severe Tropical Cyclone Zelia

On January 13, formed in the Coral Sea, northeast of Iceland Willis the tropical low 10U. This bobbing first to the west and north before it struck a south-easterly cyclone track over East. On January 14, the system is about 750 km north-east of Cairns had intensified so far that it has been upgraded from TCWC in Brisbane for tropical cyclone and was named Zelia. Zelia continued its southeastern trajectory and came under the influence of a subtropical ridge in the western Coral Sea. On January 15, the system rapidly intensified to a Category 3 cyclone and a day later the storm reached its greatest intensity west of New Caledonia. On the day Zelia crossed the 160th eastern longitude, and thus reaches the South Pacific basin, lost due to increasing wind shear and decreasing sea surface temperature rapidly in strength. He was demoted on 18 January to a tropical depression and lost in the Tasman Sea north-west of New Zealand its tropical characteristics.

Tropical Cyclone Anthony

Parallel to the coast of Queensland pulling slowly developed a low-pressure area, which on 22 January northeast of Cairns by the TCWC in Brisbane classified as Tropical Depression was 11U. The system then moved to the northeast and intensified. Late on January 22 UTC, the system has been incremented to the tropical cyclone and was given the name Anthony. After Anthony was pulled past Wlllis north Iceland, hit the cyclone a cyclone track east - south-east towards New Caledonia. On January 24, the system reached the South Pacific basin, but the returning train speed led a reversal of the direction of pull one, so the TCWC in Brisbane retained the responsibility for the primary observation of the system. During the day strong wind shear and poor organization of the system led to a weakening into a tropical low. This drew a short time in a southerly direction, then waved but a on a west- northwesterly track.

Back responsibility of the TCWCs in Brisbane intensified the depth and gained again on 29 January cyclone status. The cyclone hit a hook to the north, before he drifted steadily until his landfall north of Bowen in southeast Queensland in a southwesterly direction. Here, Anthony intensified into a Category 2 cyclone, but lost after crossing the coast rapidly in strength and was graded to a tropical depression.

Severe Tropical Cyclone Bianca

Tropical Depression 13U

Severe Tropical Cyclone Yasi

January 26, RSMC Nadi had formed of a tropical disturbance in the area of ​​responsibility, which had so far stepped up to January 30 that it received the name Yasi as a Category 1 cyclone. The cyclone moved across Vanuatu to the west, strengthened further and crossed on January 31, the 160th eastern longitude as a Category 3 cyclone. In the Coral Sea to Yasi intensified rapidly and reached on February 1, the category 5 cyclone, the Australian scale. Although Yasi weakened before landfall slightly off, reached the coast near Innisfail on February 2, but still always in the highest category. Even before the arrival of the cyclone, the Queensland Government had ordered the evacuation of vulnerable areas. Thousands of residents were taken to safety.

About Land of the cyclone rapidly lost power and slowed continuously. He lost on February 3, about 50 km east of Mount Isa the status of a cyclone.

Tropical Depression 15U

Off the coast of Western Australia was formed on February 8, a low pressure area that is constantly pulled in the following days in west- southwesterly direction. On 11 February, the Bureau of Meteorology in Perth classified the system as a tropical depression and gave him the identification 15U. The JTWC began a few hours later with the issuance of warnings under the name 14S. Although the TCWC in Perth went from an intensification of the system to a tropical cyclone of category 1, but strong wind shear and cool water surface hindered the organization, so that the system remained a deep and broke up on February 13.

Severe Tropical Cyclone Dianne

Off the north coast of Western Australia developed on February 11, a low pressure area is intensifying. Due to the proximity to the coast TCWC for the coastal towns between Onslow and Coral Bay was on January 15 from a Zyklonvorwarnung because the system had developed 350 km north-northwest of Exmouth to a tropical depression. Late on 16 February, 16U intensified to tropical cyclone and was named Dianne.

Severe Tropical Cyclone Carlos

On February 14, the Tropical Cyclone Warning Centre ( TCWC ) announced in Darwin that has evolved over the country at 13.2 ° S and 130.7 ° E, about 40 km west- south-west of Batchelor, a tropical depression. For the Northwest of the Darwin - Daly District and the Tiwi Islands a severe weather warning was issued. Through a strong subtropical ridge, the system was initially driven in a northerly to north- northeasterly direction. The only slow-moving system intensified on February 16 to a tropical cyclone and was named Carlos. About water arrived, Carlos turned to the east. Since the ridge south of the cyclone located weakened slowly, meteorologists predicted a loop in a clockwise direction before Carlos struck a southwestern cyclone track.

On February 15, fell in the region of heavy rain, the stations Marrara 179.4 mm and 131.0 mm rainfall Darwin Airport reported. In Darwin fell in the same period 339.6 mm of rainfall, which is the highest ever recorded in Darwin rainfall within 24 hours. The cyclone caused tore trees around, causing damage to buildings. Schools, the international airport and the port at East Arm were closed.

Back on land, the system weakened and was downgraded to a tropical depression. A total of 684.8 mm of rainfall were recorded within three days by the only slow-moving cyclone at Darwin airport. The system removed then slowly southwest of Darwin and moved towards the border between the Northern Territory and Western Australia. In the settlement Daly River 442 mm of rainfall were measured in connection with Carlos. On February 19, the system reached the north of the Kimberley region. However, the fallen precipitation were 90 mm and 80 mm in Wyndham no longer as high as in the days before in Kalumburu.

Early on 21 February came Carlos after passing through Kimberley back over the waters of the Indian ocean that surrounds it, which led to a renewed intensification into a cyclone. In the mining town of Karratha, a squall line of the cyclone produced a total of four tornadoes, whereby 38 houses and numerous vehicles and a school were damaged. Carlos intensified over water continuously into a Category 2 cyclone.

On February 22, the system moved parallel to the coast of Pilbara. Varanus Iceland reported a rainfall of 59 mm and the strongest gust of wind in the area was measured at 120 km / h on Bedout Iceland. The system further organized better. On February 23, was erected at this station with 283 mm on Barrow Iceland, a new rain record. The strongest gusts that day were recorded at 139 km / h on Varanus Iceland. The cyclone crossed the North West Cape and met with rain and strong winds of up to 155 km / h on Onslow and Exmouth.

Carlos went on in a southwesterly direction and moved away as the west coast of Australia. Here, the storm intensified on February 24 in a heavy tropical cyclone. About increasingly cooler water, the storm broke up on February 27.

Tropical Depression 18U

On February 25, the Tropical Cyclone Warning Centre ( TCWC ) in Perth announced the 75 km has west-northwest of Kalumburu and 445 kilometers northeast of Derby formed a tropical depression that moved slowly paraellel the coast Kimberley in a southwesterly direction. In the early morning of February 28, the low moved in the King Sound on land. To the east of Port Hedland significant rainfall was recorded on the Dampier Peninsula partly what concerned the catchment areas of Telfer River and partly De Grey River. Derby recorded on 83 mm of rain, Camballin reported 142 mm of rainfall and Looma 105 mm. The tropical depression moved further inland and the Bureau of Meteorology announced on February 28, the last warning to the system.

Tropical Depression 19U

Tropical Depression 20U

Tropical Depression 21U

On March 7, reported the TCWC Brisbane that about 1,200 kilometers west of Port Vila, Vanuatu has a tropical depression formed in the Coral Sea. During the day, the system moved eastward and intensified again the following day continually, before it moved into the South Pacific Basin from the responsibility of the Australian meteorologists and there became a Tropical Depression 12F.

Tropical Depression 22U

Tropical Depression 23U ( Cherono )

On March 10, the TCWC Perth, which had formed a tropical depression in the area of ​​responsibility of TCWCs Djakarta, about 1640 kilometers west of Jakarta, Indonesia reported. During the following two days the system wandered slowly. It came on March 13 in the area of ​​responsibility of TCWCs in Perth, before it moved westward from the Australian region in the southwest Indian Ocean. Finally, where it developed for mitigating tropical storm Cherono.

Tropical Depression 24U ( Bune )

On March 23, the TCWC Brisbane classified Tropical Depression 13F in the South Pacific Becker as Tropical Depression 24U, as there was this about 250 km north- west of Tonga. Over the following week, 24U/13F continuously intensified to tropical cyclone Bune heavy, finally 1450 km northeast of New Zealand lost its tropical characteristics. During its existence Bune always remained east of the 160th degree of longitude and thus was not a part of the Australian cyclone season.

Tropical Depression 25U

Tropical Depression 25U formed off the northern coast of Australia on March 26. On March 31, the system was reported northwest of Darwin. The system drifted first to the west, but moved to the south from April 1. On the night of April 2, 25U finally struck a path to the southwest migrated to the Kimberley coast that has to do after heavy rainfall with strong flooding. On 6 April, the low dissolved completely.

Tropical Depression 26U

Tropical Depression 27U

On March 26, reported the TCWC Perth that about 315 km northwest of the Cocos Islands have formed a weak tropical depression. During the following two days the system moved slowly westward and came briefly under the responsibility of the RSMCs Le Reunion, then returns to the responsibility of the TCWCs back, then a few days to bob up to the 90th degree of east longitude around. On 2 April, 27U broke over the open ocean to complete.

Tropical Cyclone Errol

On April 10 was formed north of the Tiwi Islands are a tropical depression, the reluctant evolved while it moved westward. The system suddenly changed its direction of pull and moved from 12 to 14 April to the southeast. On April 15, the system intensified into a tropical storm and was named Errol. After another change of course cyclone Errol migrated to the northwest and intensified on April 16 in the category 2 cyclone of the Australian scale. On April 20, Errol broke up.

Season overview

Storm names

The various Tropical Cyclone Warning Center assign the names for storms that form in their respective areas of responsibility. The storms keep their names when they move from one jurisdiction to another. However, be storms that move in the area of ​​responsibility of Météo -France in Réunion, newly named there. Storms that pass from there coming into the area of ​​responsibility of TCWC in Perth, keep those allocated in the southwest Indian Ocean name. On the following lists of names are names that have not been awarded in this cyclone season, shown in light gray.

TCWC Djakarta

The TCWC in Jakarta observed tropical cyclones that form between the equator and 10 ° south latitude and between 90 ° and 125 ° east longitude. By the Australian Bureau of Meteorology storm special instructions issued in this area to support. Should a tropical cyclone within this area of ​​responsibility form, which TCWC Djakarta assigns a name from the following list; the only 2010 assigned name was Anggrek.

TCWCs in Perth, Darwin and Brisbane

Since the start of the cyclone season 2008-2009, the Australian Bureau of Meteorology uses only a single list of names, but still operates three TCWCs, Perth, Darwin and Brisbane. This watch all tropical cyclones that form between 90 ° and 160 ° east longitude, and give out special warnings when cyclones in the responsibilities of the TCWCs arise in Djakarta or Port Moresby. The first name that was assigned, Tasha was.

The name Yasi is not on any of the lists of names for the Australian region, but was awarded in the South Pacific basin by the RSMC Nadi Fiji Meteorological Service of when the cyclone was still in its area of ​​responsibility.
