Abstract

The regional scale variability of land processes plays an important role in modulating regional climate. In this view an attempt was made to ascertain whether the characteristics of Indian summer monsoon change with orography. The regional climate model (RCM) WRFV3 was used to carry out the sensitivity experiment with and without orographic effect. The simulation results revealed that the orographic barriers enhanced the precipitation across west coast of southern peninsular India which includes Kerala and coastal Karnataka.
