Abstract
Local Severe Storm (here after referred as LSS) is a mesoscale meteorological phenomenon of strong vortex over land. Nor’westers or tornadoes are land-based local severe thunderstorms. If there is a sudden fall of pressure over a small area then, due to differential heating, supported by deep layer of atmospheric instability, there are chances of formation of local thunderstorms (Debsarma 2004). In Bangladesh, thunderstorms occur in all seasons of pre-monsoon, monsoon and post-monsoon and are characterized by strong surface wind generally from 40 to 100 miles per hour and accompanied by heavy rain and often destructive hail with lightning. The frequently occurring thunderstorms are observed during pre-monsoon months; these are known as nor’westers, because they come mostly from northwesterly direction (Afroze et al. 1981).
