On the reasons and quantified prevalent ocean atmosphere roles for the intensification and genesis features of the ESCS Tauktae.

Tauktae was an Extremely Severe Cyclonic Storm (ESCS) that occurred in the Arabian Sea (AS) during 14-19 May 2021. The present study investigates the prevalent role of the ocean/atmosphere on the genesis and intensification of it, and causative ocean-met factors from a climatological and current perspective; and tries to understand the reason of intensification though it was close (~ 140 km) to the coast. In general, the climatological Genesis Potential Index (GPI) is higher off the Indian west coast during the cyclone seasons, in which, low-level absolute vorticity (ABV) and mid-tropospheric relative humidity (RH) have major roles to play.
