A hybrid model to estimate the depth of potential convective instability during severe thunderstorms
The purpose of the present paper is to view the role of theta parameters in the genesis of severe thunderstorms of pre-monsoon season over northeastern part of India. The method adopted to achieve the objective is a Hybrid soft computing system comprising of Ampliative Reasoning (AR) and Simulated Annealing (SA). The results of the study reveal a very important finding that the occurrence of such severe weather hazard requires conditional instability up to the altitude of 4.5 km. whereas convective instability persists up to 3.5 km altitude. Thus, for the genesis of severe thunderstorms of pre-monsoon season the atmosphere must have potential convective instability up to the altitude 3.5 km and the conditional instability has to persist little more.
