2010–11 South-West Indian Ocean cyclone season

The cyclone season in 2010-2011 Südwestindik officially began on 15 November 2010 and ended on 30 June 2011, with the exception of Mauritius and the Seychelles, where they only ended on May 15, 2011. These data conventionally delimit the period of meteorological year in the southern hemisphere, in which form most of the tropical cyclones in the southwestern Indian Ocean. However, the first tropical system formed already on October 25, 2010.

Tropical cyclones in this basin are monitored by the Regional Specialized Meteorological Centre ( RSMC ) in La Réunion, France. The area of ​​responsibility of Météo -France comprises the Indian Ocean south of the equator and west of 90 ° E longitude. Tropical cyclones in this area are called cyclones. The Joint Typhoon Warning Center ( JTWC ) in Honolulu also observed the weather patterns in this area; There are storm warnings out that are primarily aimed at facilities of the Armed Forces of the United States in the Indian Ocean.

Storms

Tropical Depression 01

On October 25, at 12:00 UTC clock turned Météo -France found that has formed a tropical disturbance in the southwestern Indian Ocean. The Joint Typhoon Warning Center ( JTWC ) identified the tropical disturbance on the same day about 800 nautical miles east of Diego Garcia as a low pressure area. The system first moved in a south-easterly and then southerly direction and was upgraded to tropical depression twelve hours later. Several hours later, the JTWC classified the system directly as a tropical storm. The next day, Météo -France reported a slight weakening of the system. A few hours later classified Météo -France in Le Reunion, the system for further Abwächung into a tropical disturbance back. Late in the day the JTWC also provided a Abschwächtung of the storm into a weak tropical depression firmly and gave his last warning.

Tropical Cyclone Abele ( 02U )

On November 29, reported both the TCWC in Perth and Météo -France, the formation of tropical disturbance 02 in the southwestern Indian Ocean, not far from the area of ​​responsibility of the Australian Bureau of Meteorology, which is why the TCWC in Perth classified the system as 02U. Also, the Joint Typhoon Warning Center ( JTWC ) classified the system as a tropical and identified it as 03S, as it is about 1,300 km to the west was the Cocos Islands. On November 30, Météo -France rated highly the disturbance to a tropical depression. On December 1, the system intensified for the first tropical storm of the season and received by the Mauritius Meteorological Service the name Abele. On the same day classified Météo -France Abele high to severe tropical storm. The system intensified further to reach on December 2, the strength of a tropical cyclone. The Joint Typhoon Warning Center classified Abele as a cyclone of category 1 according to the Saffir -Simpson Hurricane Scale. On December 3, the JTWC notes that Abele has crossed on its southeast course the 90th east longitude. Thus, Abele became part of the Australian cyclone season 2010-2011.

Tropical Depression 03

Tropical disturbance 04

On January 30, Météo -France classified a low pressure area south of La Réunion as a tropical disturbance 04 The system moved southward, and the next day it had lost its tropical characteristics, so that the Météo -France issued the final warning to the system.

Intense Tropical Cyclone Bingiza

Early on 9 February rated Météo -France a low pressure area as a tropical disturbance 05. The system was located at time 260 km north -northeast of Tromelin. The system intensified several hours later in a tropical depression and after further rapid intensification on the same day in a moderate tropical storm, which was given the name Bingiza. A little later, the Joint Typhoon Warning Center classified the system as Tropical Cyclone 13S. However, the central air pressure began to rise on February 11, and the system weakened in the wake from. However, the next day the conditions were very favorable for rapid intensification, because in height no wind shear was present and prevailed a very good divergence of cirrus clouds. The near-stationary system began to intensify again and became a severe tropical storm and soon after the tropical cyclone, which eventually evolved into an intense tropical cyclone. By interacting with the landmass of Madagascar is Bingiza weakened late on 13 February to a tropical cyclone from. After landfall Bingiza about Saranambana early schw ¨ on February 14, the hurricane would like rapidly. The system has been graded to depression overland from Météo -France because of that. The depression moved slowly across Madagascar and arrived on 16 February as a tropical disturbance in the Mozambique Channel. Over water, the system intensified again to a tropical depression. Bingaza reached again briefly the status of a moderate tropical storm, but came after a change of direction again over land. The system was soon out on the south of the island in strength and eventually ceased to exist on 20 February in the southern Indian Ocean.

Bingiza resulted in the approach to Madagascar to heavy rainfall and thunderstorms that triggered localized flooding ..

Tropical disturbance 06

On February 15, Météo -France classified a low- pressure area northeast of La Reunion Tropical disturbance as '06 '. Because of moderate wind shear, the system weakened to the next day. It dissolved on 20 February to complete.

Moderate Tropical Storm Cherono

On March 14, the tropical low 23U came from the Australian region in the Südwestindik, where it was classified as a tropical disturbance 07. It intensified rapidly and was upgraded already the next day from a tropical depression into a moderate tropical storm named Cherono. On March 19, it was found that the storm weakened. On March 21, the transition began in a subtropical depression. On 23 March, Cherono had dissolved.

Tropical disturbance 08

On March 28, a territory disturbed weather moved into the southwestern Indian Ocean. It was a day later classified as a tropical disturbance 08. Although Météo -France expected an intensification of the system in a moderate tropical storm during the first days of April, but wind shear prevented an intensification, and the system dissipated on April 1.

Subtropical Depression 09

On April 13 was formed south of Madagascar a subtropical depression. Although the system reached wind speeds of a severe tropical storm, but still retains its subtropical characteristics, so it got no name. It dissolved on April 16 to have jeopardized without land.

Chronological overview of the season

Storm names

Tropical cyclones in this basin received a name, if they achieve at least the strength of a moderate tropical storm. If a system is this strength reached to the west of 55 ° E longitude, the name is assigned by the Sub - regional Tropical Cyclone Advisory Centre in Madagascar; reaches the storm of this strength between 55 ° and 90 ° east longitude, the Regional Tropical Cyclone Advisory Centre in Mauritius is responsible for the naming. New names lists are given out every year, so no names will be deleted from the list of names of tropical cyclones. The list of names for the cyclone season in Südwestindik 2009-2010 was announced by Météo -France in August 2009.
