ON THE ROLE OF WIND-INDUCED SURFACE HEAT-EXCHANGE IN A 2-DIMENSIONAL MODEL OF SUPER CLOUD CLUSTERS

Experiments with a two-dimensional model of Chao and Lin [1994] are co nducted to investigate the role of WISHE (wind-induced surface heat ex change) in the super cloud clusters. It is found that while WISHE as a n instability mechanism is not responsible for the existence of the su per cloud clusters, the process of surface fluxes being enhanced by su rface wind has the important roles of prolonging the life span of the cloud clusters and making the super cloud clusters more robust. WISHE is also found not responsible for upstream propagation of the super cl oud cluster. The latter is explained by the cloud cluster teleinductio n mechanism proposed by Chao and Lin [1994].
