中-美联合海气考察期间热带西太平洋的海面热量平衡

根据1986年1—2月中美海气考察船所获得的气象资料和其它海洋气象报告,本文计算了热带西太平洋海面的热量平衡,指出该区域海面供给大气的热量大于它从大气接受到的能量。是一个重要的热源区。同时指出,海洋向大气输送热量最显著的地区是出现在西太平洋西部的热带地区,即在 10°N、130—150°E附近。此外,在该海域内,确定海面热量平衡特性的两个最重要的因素应属潜热通量和太阳辐射通量。 

THE HEAT BALANCE OF THE SEA SURFACE IN WEST TROPICAL PACIFIC DURING SINO-AMERICA JOINT INVESTIGATION OF OCEAN AND ATMOSPHERE

Based on the marine meteorological data collected by the vessel "Xiangyanghong No.14,China" and other ships from January through February, 1986,the heat balance of the sea surface in three areas in the western tropical Pacific has been estimated in this paper. It is shown that the net heat gained by the sea surface is negative. It means the supporting energy from the sea surface to the atmosphere is larger than the energy received from atmosphere by the sea surface. It should be emphasized that the area where the heat transport from sea surface toward air is most evident is the west part of the western tropical Pacific around 10°N. Additionally,the latent heat flux and solar radiation flux should be two of the most important factors in determining the sea surface heat balance in this region.
