In the western Pacific warm pool region, convection is organized on many different temporal and spatial scales. One interesting phenomenon is the 2-3 day organization of convection whereby active cloud systems grow throughout the course of a day, then begin to decay the following day, as the atmosphere tries to return to a non-convective state. During this recovery period, detrainment brings air with lower moist static energy to the boundary layer, and decaying cloud shields serve to reduce incoming solar radiation (Chen and Houze, 1997). The net effect is a stabilization of the surrounding environment, resulting in a suppression of convective activity until the following day. In this paper, we use sounding data, Q1/Q2 budgets, and cloud type information obtained during TOGA COARE to examine the boundary layer processes which are associated with this mode of organization, as well as those observed during non-
active periods.
