Abstract : This is a study of diagnostic cloud schemes to examine the variability of cloud fractions in monsoon systems. Includes simulation the middle tropospheric cyclone (MTC) of the Asian monsoon. Cloud radiation is a key factor in the thermodynamic control of the local east-west circulation. Also showed is the coalescence of small vorticity elements; these coalesce to form a parent large scale mid-tropospheric cyclone The study of thermodynamics of this system constitutes this research. Various methods for determining precipitation rates associated with the MTC are included and precipitation is shown to be due to convective processes rather than stable processes which are characterized by the general monsoon pattern.
