On the role of wind-induced surface heat exchange in a two-dimensional model of super cloud clusters

Experiments with a two-dimensional model of Chao and Lin [1994] are conducted to investigate the role of WISHE (wind-induced surface heat exchange) in the super cloud clusters. It is found that while WISHE as an instability mechanism is not responsible for the existence of the super cloud clusters, the process of surface fluxes being enhanced by surface 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 cloud cluster. The latter is explained by the cloud cluster teleinduction mechanism proposed by Chao and Lin [1994].
