ROLE OF MOUNTAINS IN THE SOUTH ASIAN MONSOON CIRCULATION.

Abstract

At 11-level numerical model of the atmospheric circulation which has a prescribed seasonal variation of insolation and sea surface temperatures is integrated with respect to time for approximately three model years. The model is global in domain and incorporates a smoothed mountain topography. In order to investigate the role that mountains play in the south Asian monsoon circulation, a second numerical experiment, exactly the same as the first except that all mountains are removed, is integrated with respect to time from 25 March through July.
