Annual Variation Trend of Lightning Flash Activities over Sri Lanka

Languages of publication
The variation of the lightning activities over Sri Lanka and surrounded costal belt (5.75ºN-10.00ºN and 79.50ºE-89.00ºE) is studied using lightning flash data of Lightning Imaging Sensor (LIS) which was launched in November 1997 for NASA’s Tropical Rainfall Measuring Mission (TRMM). The LIS data in the period of 1998 to 2014 are based on this study and there were 23838 lightning flashes over the landmass covered by Sri Lanka during considered period. The data show that average flash density has an increasing trend of 0.093 flashes km-2 year-1. The linear trend is shown in annual flash count with the fitted straight line. Although there is a slight variation between years, there is a clearly increasing trend with 24 flashes per year. There is an incremental trend in distributing of lightning activities all over the country with time. Warming trends of surface temperature and atmosphere may have a correlation with increasing trend of the lightning activities over Sri Lanka and surrounded costal belt.
