Abstract :
During the Intensive Observation Period (IOP) of TOGA-COARE (the Tropical Ocean-Global Atmosphere program, a Coupled Ocean-Atmosphere Response Experiment), Doppler radar observation was carried out on Manus Island, Papua New Guinea. In this study, as a preliminary analysis of tropical cloud in the western part of Pacific Ocean, two cases of convective clouds are analyzed, one is the isolated convective cloud which appeared at the center of the island, the other is linear convective rainband associated with gust front. The common finding of these analyses is the temporal separation of warm rain processes and cold rain processes. This feature causes the timing of the anvil appearance and of the wind gust occurrence
