Abstract :

Fujita, Johnson and others at different times studied meso high, meso low and wake low with respect to passage of thunderstorms. In the present study, meso analysis of related atmospheric processes, i.e., surface meso highs, meso lows, and wake lows, with respect to severe local thunderstorms with Squall encountered at Alipore Observatory, occurred in pre–monsoon of 2013, has been analyzed. This has been done to improve nowcasting with respect to severe local storms. A suitable computer programme associated with departure from pentad mean may give a continuous pictorial record towards more accurate identification of meso lows ahead of the system.
