Consequences of pre-monsoon thunderstorm -A fuzzy logic approach

Abstract

Pre-monsoon thunderstorms are important as well as devastating weather events occurring over Gangetic West Bengal (GWB). The prime aim of the current paper is to introduce the concept of Fuzzy Logic to view the consequences of some important parameters during the occurrence of severe thunderstorms. The result reveals that fall in surface temperature as well as rise in relative humidity and pressure are the most important consequences during the occurrence of severe thunderstorms. The result further indicates that colossal fall in temperature and massive rise in pressure are the most desirable combination for the occurrence of such storms. The result discloses that when high wind speed is associated with sharp change in relative humidity and air-pressure, the possibility of occurrence of such weather hazards is more. The important finding of the study suggests that, for prediction of the wind speed associated with severe thunderstorms, multiple regressions, using relative humidity and air pressure as predictor,  needs to be investigated.
