A moist baroclinic model for monsoonal mid-tropospheric cyclogenesis.

Abstract

This study investigates the effects of condensational heating on the formation of a monsoonal mid-tropospheric cyclone (MTC) by applying the heating parameterization of Mak (1982) to the dynamic model of Brode and Mak (1978) except that the beta-effect is also included. It is found that the observed basic baroclinic flow with turning provides a dynamic framework conducive for a MTC-like disturbance to interact with the embedded moist convection. The joint processes give rise to an unstable disturbance that has a large but finite growth rate and an intermediate length scale.- from Author
