Tropical Mesoscale Convective Systems and Associated Energetics : Observational and Modeling Studies

The main purpose of the thesis is to improve the state of knowledge and understanding\nof the physical structure of the TMCS and its short range prediction. The present\nstudy principally addresses the fine structure, dynamics and microphysics of severe convective\nstorms.The structure and dynamics of the Tropical cloud clusters over Indian region is not well\nunderstood. The observational cases discussed in the thesis are limited to the temperature\nand humidity observations. We propose a mesoscale observational network along with all\nthe available Doppler radars and other conventional and non—conventional observations.\nSimultaneous observations with DWR, VHF and UHF radars of the same cloud system will\nprovide new insight into the dynamics and microphysics of the clouds. More cases have to\nbe studied in detail to obtain climatology of the storm type passing over tropical Indian\nregion. These observational data sets provide wide variety of information to be assimilated\nto the mesoscale data assimilation system and can be used to force CSRM.The gravity wave generation and stratosphere troposphere exchange (STE) processes\nassociated with convection gained a great deal of attention to modem science and meteorologist.\nRound the clock observations using VHF and UHF radars along with supplementary\ndata sets like DWR, satellite, GPS/Radiosondes, meteorological rockets and aircrafl\nobservations is needed to explore the role of convection and associated energetics in detail.
