Seasonal heat budget in the tropical Western Pacific Ocean in a global GCM I. General description
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.
