Description

An attempt has been made to calculate different thermodynamic parameters to check the severity of thunderstorms during the pre-monsoon season of 2013-2015 in Bangladesh. In this paper, 60 weak to severe thunderstorms events which were recorded by the Bangladesh Meteorological Department (BMD) are investigated. Lifted Index (LI), Showalter Index (SI), Total Total Index (TTI), Convective Available Potential Energy (CAPE) and Convective Inhibition Energy (CINE) are calculated to find out the most reliable index for indicating the severity. It is found that the CAPE (having magnitude of 1500 J/kg or more), SI (magnitude of less than -2) and LI (magnitude of less than -3) are the most important parameters for predicting the occurrence of severe thunderstorms and these indices have a significant skill of forecasting the occurrence of severe thunderstorms.

Promotional text

Thermodynamic parameters are one of the important tools for thunderstorm forecasting. The Earth atmosphere is a complex system it is very difficult to understand the stability indices. In this research, researcher used scientific technic and atmospheric data to understand the TS.
