摘要

本文利用1986年10-12月西太平洋的考察资料和世界月平均气候资料详细地计算了西太平洋、太平洋中部热带及其邻近地区整层气柱的辐射和热量收支。主要结果是:(1)西太平洋和太平洋中部赤道及其热带海域10-12月整层气柱是一个范围很大的强热源区,而与之相邻的赤道南北两侧的副热带海域则是较强的冷源区。我国南海也有独立的热、冷源中心。(2)上述热源区主要是降水潜热很大造成的,而冷源则是由于整层气柱辐射支出多形成的。(3)热源区的月际变化明显。

Abstract

In this paper, we have in detail computed the budgets of radiation and heat of whole air column over the tropical and its surrounding sea areas of the west? and middle-Pacific using expedition data in the west Pacific and the monthly climatic data for the world in October-December 1986. The main results are as follows: (l)The whole air column over the equator and tropical sea areas of the west-and midddle-Pacific in October-December 1986 is a strong and abroad heat source area; but over the subtropical sea areas at both south and north sides of the above area, stronger heat sink areas; over south China sea, also independent centres of source and sink of heat. (2)The formations of above heat source areas are mainly due to the very large latent heat of precipitation, and the formations of heat sink areas, large loss of radiation. (3)The inter-monthly variations of heat source areas are evident.
