The main objectives of this study are to characterize precipitation amounts over several temporal scales and to relate precipitation at the surface and aloft to particular types of events. Virga is of special interest since its presence indicates that precipitation was produced aloft but did not reach the surface. Long-term Micro Rain Radar (MRR) (from January 2010 to December 2015) data are utilized to diagnose the vertical structure of the virga precipitating clouds systems passing over Kadapa, Semi-arid regions of India. Using MRR, precipitation events are classified into three categories: convective, stratiform and virga. There was wide variation in the relative importance of stratiform and convective precipitation at the semi-arid region with, for example, some drought periods being dominated by convective and others by stratiform events. This study also quantifies the virga precipitation occurrence percentage using Micro Rain Radar (MRR) and Tropical Rainfall Measuring Mission Precipitation (TRMM) Radar (PR).
