Vertical Profiles of Rain Drop-Size Distribution over Tropical Semi-Arid-Region, Kadapa (14.47° N; 78.82 ° E), India

South-West and North East monsoon are the two important periodic winds, which show high impact on the rain. In general, the South-West (SW) monsoon spreads over the state from June to September and North-East (NE) monsoon from October to December. In this paper we present the details of vertical profiles of rainfall measured with Micro Rain Radar (MRR) deployed at Kadapa (14.47° N; 78.82 ° E), a semiarid tropical site in Andhra Pradesh, India for the period from 2009 to 2010. This paper discusses the relation between various rain drop size distribution properties such as Rain Reflectivity (Z), Rain Rate (RR), Liquid Water Content(LWC) of the rain in these two monsoons. In the present study, the Z-R relationship is obtained using linear regression. The Strati form and Convective precipitations are found to occur at different rates of rainfall
