摘要
用1958—1967年海上调查和船舶报水文气象资料,计算了渤、黄、东海海面热量平衡各分量及其总和的年平均状况;分析了各热量分量的平面分布;估算了各分量的量级;讨论了海面热量平衡与水团分布和海洋环流的关系。结果表明,在海、气界面上,海洋获得的热量主要来自太阳辐射;失去的热量主要是由于海水的蒸发;暖流区海洋失热最多,尤其在黑潮主干区明显。同时还指出,年平均各热量分量的总和基本上反映了海洋环流的形势,而海洋内部的平流热输送为本海区带来大量的热量,从而弥补了通过海、气界面海洋释放给大气的热量。
Using the data of hydrology and meteorology obtained from 1958 to 1967, the sea surface heat balance of the Bohai, Yellow and East China Seas were calculated, the distribution and magnitudes of each component were analyzed, and the relation to the ocean circulanon were discussed. The results show that, most of the heat gain of the ocean across the sea surface mainly comes from solar radiation and most of the heat loss was mainly caused by water evaporation. The maximum heat loss occurs in warm ocean current area, especially around the Kuroshio region. The results also show that, the average annual net heat flux at the sea surface can reflect the general distribution of ocean circulation; the heat loss from the sea surface to the atmosphere was compensated by the heat advection transportation of the Kuroshio warm current.
