热带西太平洋区域性大气能量收支的初步分析

本文探讨了中美西太平洋海-气相互作用合作考察期间，热带海洋不同海域上空大气能量的水平输送和局地变化。我们把热带西太平洋划分成三个多边形（东、中和西部区），分别计算了1986年1月9—15日、2月1—14日逐日三个海区上感热、潜热和位能的平均、扰动输送项、局地变化项以及各边界面上大气能量的输送。得出西太平洋西部海域上空大气柱内能量的平均输送是由外界向区内输送，而中、东部海域则相反。这表明西太平洋西部热带海洋上大气柱内增温明显，而中、东部则不然。另外，大气能量局地变化的区域性差异，其量值比输送项值要小些。

The Preliminary Study on the Budget of Regional Atmospheric Energy over West Tropical Pacific

The atmospheric energy budget calculation over west tropical Pacific during the Sino–America Sea–Air Join Investigation has been made. The controlled area is divided into three polygons (east, middle and west areas). Based the data from this investigation during the 9th through 15th of January and 1st to 14th of February, 1986, the horizontal transportation of the atmospheric energy budget is computed day by day. It is pointed that the direction of the atmospheric energy transportation in the west part of west tropical Pacific is from the outer region towards inner region, and it is in an opposite direction in the east and middle parts. It shows that over the west area the warming is obvious during the investigation period. In addition, the regional differents for the local change of atmospheric energy are less than that of the transporting terms
