North Indian cyclone seasons
2008 , 2009 , 2010 , 2011 , 2012

The cyclone season in the North Indian 2010 has no official limits as is usual in other basins, but runs all year round. The tropical cyclones usually form in this basin between April and December, with the months before and after the monsoon season , i.e. April / May and October / November, being the most active. A tropical cyclone in the Indian Ocean is known as a cyclone .

The responsible Regional Specialized Meteorological Center (RSMC) is the India Meteorological Department in New Delhi . This gives a name to those tropical cyclones that have at least the status of a cyclone. Low pressure areas (depending on the wind speed depressions or deep depressions ) are numbered consecutively, with the letter combination BOB indicating that the system was formed in the Bay of Bengal . The letters ARB stand for the Arabian Sea .

The Joint Typhoon Warning Center (JTWC) in Honolulu issues separate warnings and forecasts for the US facilities in the Indian Ocean. The JTWC classifies according to the Saffir-Simpson hurricane wind scale , while the RSMC uses its own criteria for the classification, which are based, among other things, on the measurement of the continuous wind speed on the basis of a three-minute observation.

Storm names

Tropical cyclones in the Indian Ocean are named by the RSMC of the India Meteorological Department . The names are used only once each, so no devastating storm names are removed from the list of tropical cyclone names after the season ends .

  • Laila
  • Bandu
  • Phet
  • Giri
  • Jal
  • Keila  (unused)

Storms

Severe cyclonic storm Laila

Severe cyclonic storm ( IMD )
Category 1 cyclone
Laila.A2010139.0810.1km.jpg Laila 2010 track.png
Duration May 17th - May 21st
intensity 55 kn (100 km / h ) (3 minutes) , 986 hPa

On May 17, the India Meteorological Department (IMD) upgraded a low pressure area to a tropical depression and classified it as BOB 01 . The system was located approximately 930 km east-southeast of Chennai , India at that time . The system intensified rapidly and reached the strength of a tropical cyclone on May 18, approximately 450 km east-southeast of Chennai and 1200 km south-southwest of Kolkata . Due to favorable conditions, Laila was able to intensify and was upgraded to a severe cyclonic storm on May 19 at 6:00 a.m. UTC . The proximity to the mainland and increased wind shear indicated a weakening of the cyclone, which at that time was 120 km northeast of Nellore and 100 km southeast of Ongole .

The cyclone crossed the coast of Andhra Pradesh on May 20 between 11 a.m. and 12 noon UTC near Bapatla in the Guntur district . Over land, the cyclone quickly lost its power, which is why the RSMC suspended the warnings on May 21.

Cyclonic storm Bandu

Cyclonic Storm ( IMD )
Tropical storm
Bandu 21 May 2010.jpg Bandu 2010 track.png
Duration May 19 - May 23
intensity 40 kn (75 km / h ) (3 minutes) , 994 hPa

On May 19, the JTWC found that a tropical storm had formed in the Arabian Sea. The IMD classified the system as depression during the day and assigned the designation ARB 01 . A few hours later, the RSMC New Delhi upgraded the depression to a deep depression. On May 20, the RSMC downgraded the system. However, it was able to intensify again the next day and was eventually classified as a tropical cyclone and named Bandu.

That day, the cyclone made the cargo ship Dubai Moon unable to maneuver. The ship's 23 crew members were rescued by helicopters from the British frigate HMS Chatham . The cargo ship floating off the Somali coast later sank.

Very severe cyclonic storm Phet

Very Severe Cyclonic Storm ( IMD )
Category 4 cyclone
Phet 2010-06-02 0655Z.jpg Phet 2010 track.png
Duration May 30th - June 7th
intensity 85 kn (155 km / h ) (3 minutes) , 970 hPa

On May 31, the IMD upgraded a low pressure area 925 km southwest of Mumbai to a tropical depression and named the system ARB 02 . The next day the system had intensified to a deep depression, the JTWC saw a further intensification during the day. The RSMC New Delhi declared the system a tropical storm on June 1st and named it Phet . On June 2, Phet intensified rapidly and was upgraded to a severe cyclonic storm and then a very severe cyclonic storm. On the southwestern edge of a subtropical ridge, Phet moved in a northwestern direction towards Oman from its formation .

The cyclone gradually turned north and crossed the coastline north of Marira. He moved overland to the Gulf of Oman , which he reached at Sur . Over the waters of the Gulf, the cyclone was deflected to the east by the influence of the west wind zone and the train speed increased. This, the influence of the Balochistan coast and moderate wind shear led to the weakening of Phets. As a tropical low pressure area, Phet passed the 15.7 million-inhabitant agglomeration of Karachi and arrived overland.

A total of 44 people died as a result of the storm.

Depression BOB 02

Depression ( IMD )

Duration October 7th - October 9th
intensity 25 kn (45 km / h ) (3 minutes) , 996 hPa

On October 7, the India Meteorological Department upgraded a low pressure area to a depression and classified the system as BOB 02 . At that time, the depression was about 180 km southeast of Visakhapatnam . Later that day, the IMD found that the system was moving away from Visakhapatnam while maintaining its strength. A landfall was predicted for the section between Gopalpur and Paradip , but late on October 7th the depression swept over Paradip. On October 8, the RSMC in New Delhi reported a slight weakening of the system. During the course of the day, the system weakened further and reached Kolkata in West Bengal for the second time overland. The system continued to weaken on its way northwest, was then caught by the jet stream and finally absorbed by an extratropical storm in the early hours of October 9th.

Deep Depression BOB 03

Deep Depression ( IMD )

Duration October 13th - October 16th
intensity 30 kn (55 km / h ) (3 minutes) , 995 hPa

On October 13, the India Meteorological Department (IMD) upgraded a low pressure area to a depression and designated it BOB 03 . At that time, the depression was about 700 km east of Visakhapatnam. The system intensified further during the day. On October 15th, the IMD upgraded the system to Deep Depression. On the night of October 16, the system came overland near Gopalpur and began to lose power early on October 16. In the course of the day, the depression weakened to a residual low.

Very severe cyclonic storm Giri

Extremely severe cyclonic storm ( IMD )
Category 4 cyclone
Giri.A2010295.0655.250m.jpg Giri 2010 track.png
Duration October 20 - October 23
intensity 105 kn (195 km / h ) (3 minutes) , 950 hPa

On October 20, the India Meteorological Department (IMD) upgraded a low pressure area to a tropical depression and classified it as BOB 04 . At the time, the system was about 250 km southwest of Sittwe , Myanmar . In the early hours of October 21, the depression intensified into a deep depression and on the same day the Joint Typhoon Warning Center (JTWC) classified the system as Tropical Cyclone 04B . The system later intensified and was upgraded to cyclonic storm Giri by the IMD. By October 22nd, Giri intensified into a very severe cyclonic storm. During the day the storm intensified further and became the strongest cyclone of the season. Giri achieved the greatest intensity with three-minute continuous wind speeds of 165 km / h and a minimum central air pressure of 950 hPa. The cyclone landed near the city of Kyaukpyu in Rakhine State (formerly: Arakan). At midnight on October 22nd, the system began to weaken. As the system advanced further inland and reached the rugged mountains of Myanmar, it quickly weakened. At noon on October 23rd, Giri had weakened into a cyclonic storm. The cyclone also moved northeast over land and weakened further during the day; late on October 23, the RSMC New Delhi found that the cyclone had collapsed to a residual low.

Severe cyclonic storm Jal

Duration November 1st (from the Pacific) - November 8th
intensity 60 kn (110 km / h ) (3 minutes) , 988 hPa

On October 28, a tropical fault formed in the South China Sea south of Vietnam . Over the next few days the system migrated westward and northwestward, intensifying. On October 31st, the system organized itself into a tropical depression. On November 1, the system crossed the Malay Peninsula and entered the Bay of Bengal south of Myanmar. The system moved further west and strengthened.

On November 2nd, the IMD determined that the system had weakened into a low pressure area, which, however, had good prospects for re-intensification. Late on November 3rd, the JTWC issued a Tropical Cyclone Formation Alert. Early on November 4th, the IMD upgraded the system and classified it as Depression BOB 05. The Joint Typhoon Warning Center named the system 05B . Early on November 5th, the IMD upgraded Depression to Deep Depression. This intensified further and was upgraded to a cyclonic storm. The system was named Jal . The storm gained strength over the next two days and was upgraded to a severe cyclonic storm on November 6th. On November 7th, Jal began weakening. and a few hours later the RSMC reported the weakening into a cyclonic storm. During the day, the JTWC downgraded Jal from a Category 1 cyclone to a tropical storm and a few hours later the RSMC in New Delhi found that Jal had weakened into a deep depression. A few hours later, the system moved across the country near Chennai at this intensity level .

Cumulative precipitation distribution related to the cyclone

Overland, the system quickly lost strength and was downgraded to a depression early on November 9 and declared a residual low during the day. This residual low moved further in a northwest direction and the IMD assumed that this residual low could re-intensify in the northeast of the Arabian Sea, and when the system reached the Arabian Sea in the early morning of November 9th, the system actually strengthened somewhat, but crossed the system did not move to the Arabian Sea as predicted, but moved north on the west coast of India. Due to the prevailing winds, the system soon came over land again and disintegrated.

The heavy tropical rainfall associated with Jal resulted in floods in Thailand, northern Malaysia, Sri Lanka and parts of Andhra Pradesh, India, killing at least 118 people. The storm and flood-related property damage o related to Jal was put at more than 1.7 billion US dollars, the majority of which was in Thailand.

Depression BOB 06

intensity 25 kn (45 km / h ) (3 minutes) , 1000 hPa

At the beginning of December a low pressure area formed over the Bay of Bengal, which slowly moved towards the Indian coast and developed better in the process. The India Meteorological Department (IMD) upgraded the system to a depression on December 7th. At that time the system was about 450 km south-southwest of Visakhapatnam in Andhra Pradesh . Until the landfall at Bapatla on December 8 , the system migrated further northeast. Shortly afterwards, the system weakened to a residual low over land.
