本文根据我们收集的1958—1970年约150万组的船舶水文气象观测资料、计算、分析了西北太平洋热量收支分量的时空特征。在计算蒸发与热交换时,其扩散(交换)系数不是常数,它取决于各海区计算月的风速和大气层结特征。 分析表明,本海区海面年总热量差额最大负值中心恰好位于黑潮暖流的主轴附近,正值中心出现在印尼苏拉威西海域,总热量收支差额存在明显季节变化,洋流和东亚季风对这种时空特征的形成起重要作用。
Based on the hydrographic and meteorological observations of about 1.5 million ships from 1958 to 1970 collected in this paper, we calculated and analyzed the spatio-temporal features of the caloric expenditure and balance in the western North Pacific. The diffusion (exchange) coefficient is not constant when calculating evaporation and heat exchange, and it depends on the monthly wind speed and the characteristics of the atmosphere stratigraphy calculated for each sea area. The analysis shows that the maximum negative center of annual total calorific value of the sea surface in the sea area happens to be near the main axis of the Kuroshio current and the positive center appears in the Sulawesi Sea of Indonesia. There is a clear seasonal variation in the total calorie balance between the ocean current and the East Asian monsoon The formation of this spatio-temporal feature plays an important role.
