Influence of weather factors on the effectiveness of lightning in Iraq

Abstract

The lightning phenomena which accompany thunderstorms is considered as one of the important phenomena, which has direct influence on human life, his properties so far this phenomena has been studied since more than two centuries and a half just to expose the mysteries and place of where it is happening and how to get benefit of it. So this research aims to study the relation between lightning activity total flashes (N) and some atmospheric factors which are represented by the mean monthly wet bulb temperature (Tw) and the mean monthly relative humidity (RH) the results has been shown, it seems that part of it takes direct relation while the other takes an opposite relation for the days that lightning phenomena happen in and for rainy season selected station stations in Iraq.The results of the relation between lightning activity (N) and the geographical location, show that the former (N) has increased toward the Equator and getting less away from it, this increase and decrease belong to the Convection Available Potential Energy [CAPE]
