Bay of Bengal (BoB) has been very active basin this season. Month of March is largely a transition period and therefore remains devoid of any major weather activity. Except South Peninsula, most other pockets remain dry. Heat starts building up over Gujarat, Rajasthan and Odisha. Pre Monsoon thunderstorm remain mostly confined to Tamil Nadu and Kerala and occasionally stray over Karnataka, Andhra Pradesh, Maharashtra and Telangana.
Indian Seas, both Bay of Bengal and Arabian Sea , remain dormant to any stormy activity. Cyclogenesis remains absolutely scarce and only freak occurrence are on record, that too limited towards fag end of the month. March 2022 has been an outlier, wherein BoB has been hosting series of weather systems, both weak and strong in a spaced interval. Extremely unusual storm 01B developed in the 1st week itself, albeit failed to strike the Indian coastline. Like its fluky predecessors, storm remained weak and got diffused over the open waters.
Andaman Sea, Southeast BoB and neighboring equatorial Indian Ocean have been the hotbed for cyclonic features this season. Very shortly, Sun is going to cross over to the Northern Hemisphere. Along with this, Inter Tropical Convergence Zone (ITCZ) is expected to become more active on the northern side of equator and Indian Ocean. Presently, numerical models are showing a ‘suspect area’ which need to be observed closely for any further development. Next 48hr become crucial for its sustenance and further growth. Like the previous system 01B, this also will have to survive against all odds, battling environmental conditions. Even if the disturbance grow in the due course of time, the coastline of Myanmar and Bangladesh remain favorite. More often than not, Indian shore remain immune to any ill effects of such seasonal hazards.
