DIURNAL VARIATION OF SUMMER RAINFALL OVER MALAYA

Abstract

Throughout the summer, Malaya is overlain by a warm, moist, conditionally unstable equatorial maritime airmass. Mean rainfall patterns of the typical summer month of August cannot be explained simply in terms of orography acting on the prevailing low-level southwesterlies; neither can afternoon convectional heating be directly related to the peninsula's wide variety of diurnal rainfall variations. Five different diurnal rainfall patterns are identified and shown to derive from interactions among the southwesterlies (synoptic wind), local land, sea, anabatic and katabatic winds and the topography. Computations based on pilot balloon data indicate that the land and sea breezes diverging from or converging into the peninsula can cause massive lifting of air to the free convection level.
