Two non-hydrostatic mesoscale models, namely the Regional Atmospheric Modelling System (RAMS) and the PSU/NCAR Fifth-Generation Mesoscale Model (MM5) have been used to simulate various meteorological features associated with the tropical cyclones formed over the Bay of Bengal. Some of the simulation results, such as the horizontal distributions of winds, temperature, associated rainfall, cyclone tracks, moisture convection and height of the planetary boundary layer have been presented. These results are compared with the observations to assess the capability of these models in simulating various meteorological phenomena over the Indian subcontinent and it is established that the RMS errors for predicted zonal winds U, the meridional winds V, and the temperature T are within the acceptable limits. Both the models are also able to produce the warm core structure of the tropical cyclones. We also highlight a few potential areas of research to improve the model simulations of various weather events, specific to this region. [References: 22]
