摘要

Abstract

This paper describes the large scale aspects of the seasonal surface heat budget and discusses its main forcing mechanisms in the tropical Western Pacific Ocean. The high-resolution general circulation model (Semtner & Chervin

1992) used in this study reproduced well the observed upper-layer thermal structure and circulation. It is shown that at least on the average of the study region (20 °S–20 °N

west boundary −160 °E) the semiannual variation is a dominant signal for all heat budget components and is presumably due to the sun’s passing across the equator twice a year

but that the components have substantial differences in amplitude. The local Ekman divergence in the region does not change significantly through the year. As a result

the change in surface heat content is roughly half due to ocean-atmosphere heat exchange and half due to heat advection by remotely forced vertical motion. Horizontal currents do not play a significant role directly by advection

because the water which enters the region is not very much different in temperature from the water which leaves it.
