Study of the impact of high resolution ROMS-SST on the simulation of two intense tropical cyclones over Bay of Bengal using ARW modeling system

Impact of high-resolution Sea Surface Temperature (SST) derived from the Regional Ocean Modeling System (ROMS) on two intense vortices (Phailin and Hudhud) developed over Bay Bengal (BoB) are investigated. The validation ROMS-SST with various observational datasets available BoB showed a reasonably good correlation greater than 0.90. root mean square difference is around 0.40 °C. Instigating as lower boundary condition to Advanced weather research (ARW) model improved TC intensity rainfall location for Phailin. A minor improvement observed in Hudhud. Still, better replication wind structure control experiment, which uses low-resolution Reynolds-SST global output. This right sector peak latent heat pattern matches deep convection infrared satellite imagery both TCs ROMS experiment compared experiment. However, simulated track did not improve all initial conditions TCs. present modeling study compliments use higher resolutions SST downscaled by mesoscale regional ocean simulations
