2022 North Indian Ocean cyclone season

Deep depression (IMD)
Tropical storm (SSHWS)
Duration	March 3 – March 6
Peak intensity	55 km/h (35 mph) (3-min)  1002 hPa (mbar)

Towards the end of February, a cyclonic circulation had formed over the Strait of Malacca and the adjoining Andaman Sea,[6] which later intensified into a low pressure area on midday (17:30 IST) of February 28, as the disturbance formed a low-level circulation, according to a INSAT-3D satellite imagery.[7][8] Early the next day, at 09:00 UTC (14:30 IST), the disturbance further intensified into a well-marked low pressure area, as it developed a defined cyclonic vortex,[9] and three-and-a-half-hour later, the United States-based Joint Typhoon Warning Center (JTWC) started monitoring the same disturbance as Invest 90B.[10] On March 3 of midnight (05:30 IST), the well-marked low organized to a depression and the India Meteorological Department (IMD) identified the system as BOB 01, making it the first system of the season.[2] This intensification was possible because of a favourable Madden–Julian oscillation (MJO) phase, along with a feeble easterlies outflow. Sea surface temperature (SST) was also warm enough (27–28 °C (81–82 °F)) for cyclogenesis to take place, along with moderate to high vertical wind shear.[2] During the next day, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) on the system.[11] The depression subsequently intensified into a deep depression,[3] and by 21:00 UTC (02:30 IST), the JTWC started initiating advisories for Tropical Cyclone 01B.[12] After maintaining its intensity for a day, the JTWC issued its last warning for the system, at 15:00 UTC (20:30 IST) as the increasing dry air had weakened its convective mass.[13] The IMD subsequently weakened back to a depression due to the same reason.[14] On March 6, the IMD issued its last advisory for the system and downgraded it to a well-marked low pressure area, as its convective mass got further disorganized by the wind shear.[4]

In mid-March, a low-pressure area formed in the southwest Bay of Bengal, offshore of Sri Lanka, which later intensified into a well marked low pressure area, the JTWC started monitoring the disturbance as Invest 91B [15][16][17] It meandered east-southeast for three days, and on March 20, the IMD reported that a depression formed over the Bay of Bengal, giving it the designation BOB 02.[18] On that day, the JTWC issued a TCFA for the system.[19] The system gradually intensified, into a deep depression by 00:00 UTC (05:30 IST) the next day,[20] as the convection had further organized favorable conditions such as moderate to high sea-surface temperatures.[20] On March 22, the JTWC cancelled the TCFA due to the land interaction in Myanmar until the landfall.[21][22] BOB 02 rapidly weakened overland, degenerating into a depression[23] and by 03:00 UTC (08:30 IST) the next day the system weakened into a well-marked low pressure area and IMD issued last advisory.[24]
