Pre-monsoon being the beginning of the wet period after a long dry spell (November to February) has great importance from various aspects, especially from agricultural, forestry and hydrological point of view. The environmental problems in the region related to pre-monsoon Thunderstorm and rainfall are caused due to the scarcity of both surface and ground water. Hardening and cracking of agricultural fields because of prolonged drought, severe weather conditions like dust-storm, frequent thunderstorms, sometimes having very destructive mood causing heavy loss of property livestock and human life, heavy torrential rain etc are the common environmental problems during this season. These entire problems disturb the normal life of the people of the region during pre-monsoon season. Moreover besides being complex areal and temporal variation patterns of thunderstorm in the region due to its unique physiographic setting, various characteristics of rainfall and persistency of rain associated with thunderstorm vary significantly from place to place. Keeping all these point in mind a study on the characteristics of pre-monsoon thunderstorm of the region has been made. Investigation of the synoptic situations associated with the occurrences of pre-monsoon thunderstorm in the region has also been incorporated in the present study.
