Abstract

In the present study, the latest version of the Abdus Salam International Center for Theoretical Physics (ICTP) Regional Climate Model version 4.3 (RegCM4.3) is used to simulate the onset phase of summer monsoon over India during 2001-2005. The different cumulus convection schemes viz. Kuo, Mix98, Mix99, Emanuel, Grell and Tiedtke of RegCM4.3 are evaluated at 50 km horizontal resolution. The simulated precipitation is systematically evaluated with actual onset dates over 14 stations using six convection schemes, out of which Mix98 (Grell over land and Emanuel over the ocean) scheme performs well as compared to the other schemes.
