Research Abstract

Convective clouds developed over tropical oceans affect not only tropical meteorology but climate in Japan through large-scale atmospheric circulation. In order to better understand the mechanism controlling convective development, a satellite data analysis was carried out with focus on the interrelationship among the Madden-Julian Oscillation (MJO), Kelvin wave, and equatorial Rossby wave. Also explored is the mechanism that maintains the east Pacific inter-tropical convergence zone (ITCZ) so that air-sea interaction through wind and ocean currents is clarified.
