Abstract: Simulation of three severe local storms occurring over Gangetic West Bengal and surrounding areas in pre-monsoon season has been attempted with the help of mesoscale model MM5. All three storms are associated with wind squall and propagating type thunderstorm cell formation. It has been noted that the simulation is closest when the cumulus cloud parameterization scheme of Grell, cloud microphysics scheme of Schultz, Hong-Pan scheme for planetary boundary layer process, 5-layer soil model for land surface process and no shallow convection scheme are considered. The simulation is validated by 24 h accumulated rain observation at various surface observatories, by location, duration, and magnitude of maximum rain; by location, time of occurrence and magnitude of maximum wind; and by two products of the Doppler radar located at Kolkata. It has been noted that the model can reproduce wide spread rain as well as wind squall, even with limited regional data input, though there is spatial and temporal shift. Verification with the help of Doppler radar seems to be better, particularly close to the time of occurrence of the system. The model can simulate the propagation of thunder cell as noted by the radar though there is spatial as well as temporal shift. Therefore, one can simulate the broad features of severe local storm even with limited input of regional data
