Abstract

TRMM is a research satellite designed to monitor and study tropical rainfall and the associated release of energy that helps to power the global atmospheric circulation shaping both weather and climate around the world. Several methods have been used to improve understanding of climate space ground control center as the interaction between humidity, clouds and precipitation. Lightning Imaging Sensor (LIS) is one of TRMM satellite instruments which comprises of a staring imager optimized to locate and detect lightning with storm-scale resolution from 4 to 7 miles over a large area (600 x 600 km) from the earth's surface. This study present analysis on lightning features in Mid Latitude Region. In this study, we are investigating of lightning distribution from flash by measuring timely in Washington DC (38.54°N, 77.2°W) during January –April 2011 which useful to learn flashes passes through TRMM Satellite. A total 3,502,158 flash found during four month observation in this study. The highest number of flash occurs in April 2011 is 3,358,521 flashes compared to January 2011 showing the lowest flash about 3,993 flashes. This is because climate and atmosphere change that happened in Washington DC. During seasonal observation show that the spring season during March and April has highest creation of lightning compared to winter season in January and February.
