Template:Infobox weather eventTemplate:Infobox weather event/IMDTemplate:Infobox weather event/JTWCTemplate:Infobox weather event/EffectsTemplate:Infobox weather event/Footer Severe Cyclonic Storm AsaniTemplate:Efn was a strong tropical cyclone that made landfall in India in May 2022. It was the strongest storm of 2022 North Indian Ocean cyclone season. The third depression and deep depression, and the first named storm of the 2022 North Indian Ocean cyclone season, Asani originated from a depression that the Indian Meteorological Department first monitored on 7 May. Conditions rapidly favored development as the system became a deep depression by that day before intensifying to a Cyclonic Storm Asani. On the next day it further intensified and peak to a severe cyclonic storm, before making landfall as a deep depression system over Andhra Pradesh. It degenerated into a well marked low-pressure on 12 May.

Meteorological history

Template:Storm path During the first week of May, a strong pulse of Madden–Julian oscillation (MJO) and Equatorial Rossby wave (ERW) prevailed in this basin. These two conditions led to a formation, of a cyclonic circulation, over the southern Andaman Sea on 4 May.[1][2] At the same day, a Westerly wind burst occurred which resulted in formation of twin cyclones over the Indian Ocean, the southern hemisphere counterpart being Tropical Cyclone Karim and the northern hemisphere counterpart being this cyclonic circulation.[1][2][3] The United States Joint Typhoon Warning Center (JTWC)Template:Efn followed the suit and designated as Invest 92B on the next day.[4]

During 6 May, under the influence of the disturbance, a low pressure system formed off the coast of Andaman and Nicobar Islands.[5] Subsequently, the JTWC issued its Tropical Cyclone Formation Alert (TCFA), as it had rapidly consolidated its convective structure for the past few hours, along with development a well-defined low-level centre.[6]

Late on 7 May, the system developed into a well-marked low pressure area over the same region.[7] At 09:00 UTC, the JTWC initiated advisories on the system and classified it as Tropical Cyclone 02B, while India Meteorological Department (IMD)Template:Efn simultaneously designated it as Depression BOB 03.[8][9] Three hours later, the system was further upgraded to a deep depression status by the IMD as it tracked over warm sea surface temperatures of Template:Convert.[10] By 00:00 UTC the next day, the system intensified into cyclonic storm and was assigned the named Asani, becoming the first cyclone of the season.[11] Nine hours later, the JTWC upgraded it to a Category 1-equivalent system on the Saffir–Simpson hurricane wind scale (SSHWS).[12] At 12:00 UTC, the IMD further upgraded it to a severe cyclonic storm, as the Microwave imaging shows well-organized system.[13]

The cyclone began to encounter high wind shear due to which the JTWC downgraded it as a tropical storm on 10 May, while the IMD continue to maintain it as a severe cyclonic storm.[14][15] it began to make a sudden westward jog and mild decrease in wind shear made the JTWC to upgrade it again into a Category 1-equivalent tropical cyclone.[16] Nine hours later, Cyclone Asani was further downgraded into a tropical storm, it began to weaken due to higher wind shear as well as dry air intrusion.[17] Thereafter, storm rapidly weakened into a cyclonic storm on 11 May.[18] At 12:00 UTC it further degenerated into a deep depression as made landfall in Indian State of Andhra Pradesh.[19] The JTWC discontinue advisories for the system, at 15:00 UTC [20] The next day, The IMD reported that the system had weakened into a depression while moving inlands.[21] Asani eventually degenerated into a well-marked low pressure area and IMD issued its last advisory.[22] Template:Clear
