North Indian Ocean cyclone seasons 2008, 2009, 2010, 2011, 2012 |
The 2010 North Indian Ocean cyclone season was a very active event in the annual cycle of tropical cyclone formation with some 8 depressions and 6 named storms, nearly above the average of 4-6 storms in the region due to a moderate La Niña.[1] The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center releases unofficial advisories to the Indian Ocean in the Northern Hemisphere, east of the Horn of Africa and west of the Malay Peninsula. There are two main seas in the North Indian Ocean — the Arabian Sea to the west of the Indian subcontinent, abbreviated ARB and the Bay of Bengal to the east, abbreviated BOB by the IMD. The Season officially started on May 17, 2010 with Cyclone Laila and ended on December 8, 2010. During the season, the cyclones Laila, Phet, Giri and Jal along with Bandu caused excessive life loss across the Indian Subcontinent and the Middle east.
This is the only season to have 5 named storms since the 1998 North Indian Ocean cyclone season. Multiple storms together killed some 402 people wreaking damage worth atleast US$ 2.985 billion. Albeit very active, no tropical storms formed between mid June and early October because of a very strong Southwest monsoon, a weather anomaly that caused the 2010 Pakistan floods.

On May 17, the India Meteorological Department (IMD) upgraded an area of low pressure to a depression, giving it the designation "BOB 01".[2] At that time, the depression was located approximately 930 km (580 mi) east-southeast of Chennai, India.[3] Later that day, the IMD upgraded Depression BOB 01 to a deep depression.[4] That evening, the Joint Typhoon Warning Center (JTWC) designated the system as Tropical Cyclone 01B.[5] The next morning, the deep depression strengthened further and was upgraded to a cyclonic storm and named "Laila" by the IMD.[6] The storm continued to grow and became a severe cyclonic storm by May 19, it was given a Category 1 tropical cyclone status by the JTWC. Later the same day, it started weakening. On May 21, Laila dissipated completely.
The storm made landfall near Bapatla, Guntur District as a tropical storm between 1100 UTC—1200 UTC on May 20.[7]

On May 19, the JTWC reported that Tropical Storm 02A had formed.[8] Later that day, the IMD upgraded the system into a depression and designated it "ARB 01". The IMD further upgraded the depression into a deep depression that same evening. Late, May 20, the IMD downgraded ARB 01 to a depression over the coast of Somalia. However the next day it strengthened again to become Cyclonic Storm Bandu. The storm then weakened and dissipated on May 23.[9]
The island "Abed Alkorey" in Yemen was hit by the storm causing a death of one girl and destruction of many houses in the island.[10] On May 20 the storm disabled a cargo vessel, MV Dubai Moon, and left it drifting off the Somali coast. 23 crew members were rescued by helicopters from the Royal Navy frigate HMS Chatham.[11] The cargo ship later sank.

Early on May 30, the India Meteorological Department (IMD) and the Joint Typhoon Warning Center (JTWC) reported that an area of low pressure had formed about 925 km (575 mi), to the southwest of Mumbai, India. The area of low pressure had loose organized convection developing around the low level circulation center within the monsoon trough. The system was located to the south of a high pressure center anchored over Oman in an area of moderate vertical windshear. On May 31, the India Meteorological Department (IMD) upgraded an area of low pressure to a depression, giving it the designation "ARB 02".[12] The IMD further upgraded the depression into a deep depression the next day.[13] JTWC reported the same day that a Tropical Storm had formed.[14] On June 1, IMD upgraded the system into a cyclonic storm and named it "Phet".[15] The storm intensified to a Severe Cyclonic Storm in early hours of June 2.[16] The same day IMD upgraded the storm to a Very Severe Cyclonic Storm.[17] By the 5th, the cyclone had been downgraded to a cyclonic storm by the IMD as it passed over the Gulf of Oman.[18] On the 7th, Phet dissipated completely.[19]

On October 7, the India Meteorological Department (IMD) upgraded an area of low pressure to a depression, giving it the designation "BOB 02". At that time, the depression was located approximately 180 km (110 mi) southeast of Visakhapatnam.[20] Later that day, the IMD reported that the system was 120 kilometres (75 mi) east of Visakhapatnam.[21] On the same day, the IMD reported that the system moved away from Visakhapatnam and maintained strength. The system was forecast to make landfall between Gopalpur and Paradip overnight, but instead, the depression made landfall over Paradip late on October 7.[22] On October 8, the IMD reported that the system weakened slightly.[23] Later on that day, the IMD reported that the depression further weakened.[24] The storm made its second landfall at Kolkata, West Bengal, India.[23] Signal 3 cyclone alert was issued at the Maritime ports of Chittagong, Cox's Bazar and Mongla.[25] The Depression continued to weaken, as it moved northwest, until it was caught up in the jet stream and completely absorbed by a non-tropical storm, early on October 9.[26]
11 people were killed in the submerged coastal areas of Bangladesh on the day when storm crossed the land. Tens of thousands of people are stranded as waters triggered by a tidal surge inundated thousands of homes in the low-lying coastal zone.[27][28] The heavy rain took the toll further to 17.[29][30]

On October 12, a disturbance formed in the South China Sea, just off the eastern coast of Borneo. During the next few days, the system entered the border of the east Indian Ocean and intensified slightly.[51] As soon as the system entered the eastern border of the Bay of Bengal, which was on November 1, the IMD immediately upgraded the disturbance into a depression, because the system had already organized itself on October 31, which was a day before the system entered the IMD's area of responsibility.[52] Later on November 1, the system began showing signs of further, but slow organization, as the system continued moving west slowly.[53] on November 2, the Malaysian Meteorological Department (MMD) also issued their first advisory on the system, and simply called it Depression.[54] Later on that day, the IMD reported that the system had weakened into a low pressure area, but they forecasted it to become a depression soon again.[55] Late on November 3, the Joint Typhoon Warning Center (JTWC) issued a tropical cyclone formation alert on the system.[56] Early on November 4, the India Meteorological Department (IMD) upgraded the area of low pressure to a depression giving it the designation "BOB 05".[57] That day, the Joint Typhoon Warning Center (JTWC) designated the system as Tropical Cyclone 05B.[58] Early on November 5, the IMD upgraded Depression BOB 05 to a deep depression.[59] Later, the deep depression strengthened further, prompting the IMD to upgrade it to a cyclonic storm, and was named "Jal."[60] The storm continued to grow and became a severe cyclonic storm by November 6.[61] Soon afterwards, it was upgraded to a Category 1 Tropical Cyclone by the JTWC.[62] On November 7, Jal started weakening.[63] Soon afterwards, the IMD reported that Jal weakened into a Cyclonic Storm.[64] Later that day, the JTWC downgraded Jal into a Tropical storm.[65] Late on the same day, the IMD reported that the storm weakened into a Deep Depression.[66] As a deep depression, the system made landfall at Chennai, a few hours later.[67] The system continued to weaken and became a depression by early hours of November 8.[68] The depression continued to weaken until it dissipated into a remnant low on the same day.[69] On that very same day the IMD said that there was a possibility of Jal's remnants regenerating over the north east Arabian Sea.[70] And as the IMD said, the system moved into the Arabian sea without weakening by early November 9th.[71] But instead of crossing the Arabian Sea, the system moved north along the western coast of India, restrengthening slightly, but not enough for it to regenerate completely. Within a few hours, the storm started moving inland, due to the prevailing winds. The system rapidly weakened as it moved farther inland over the next few days, causing severe flooding along the way. Early on November 12, the remnants of Cyclone Jal were completely absorbed by a non-tropical low over the Himalayas.

In early December, a low pressure area formed over the Bay of Bengal. The low pressure area moved towards the Indian coast and became more well marked. On December 7, the India Meteorological Department (IMD) upgraded the area of low pressure to a depression giving it the designation "BOB 06". At that time it was located approximately 450 kilometres (280 mi) south-southwest of Visakhapatnam, Andhra Pradesh, India.[72] Until December 8, the depression moved northwestwards and made landfall at Bapatla, Andhra Pradesh, India where it dissipated into a remnant low soon after the landfall.[73][74]

Within this basin, a tropical cyclone is assigned a name when it is judged to have reached Cyclonic Storm intensity with winds of 65 km/h (40 mph). The names were selected by members of the ESCAP/WMO panel on Tropical Cyclones between 2000 and May 2004, before the Regional Specialized Meteorological Center in New Delhi started to assign names in September 2004. There is no retirement of tropical cyclone names in this basin as the list of names is only scheduled to be used once before a new list of names is drawn up. Should a named tropical cyclone move into the basin, from the Western Pacific then it will retain its original name. Five tropical cyclones have been named Laila, Bandu, Phet, Giri, and Jal on reaching Cyclonic Storm status by the IMD.
