本文利用1987年10—11月西太平洋考察获得的水文气象资料和海面辐射资料,计算了海气间感热、潜热及海面热量平衡的逐时值及日总量。分析了各通量的逐时变化特征、日变化规律及热量平衡的时空变化特征。分析表明:调查海区的第一阶段热量平衡为负,即海洋失去热量;第二阶段热量平衡为正,即海洋得到了热量。调查海区的热最平衡是东部大于西部。
Based on the hydrological and meteorological data obtained from the Western Pacific Expedition from October to November 1987 and the sea surface radiation data, this paper calculates the hourly values and total daily heat balance of sensible heat, latent heat and sea surface heat. The characteristics of hourly rate variation, diurnal variation and spatio-temporal variation of each flux were analyzed. The analysis shows that the heat balance in the first phase of the surveyed sea area is negative, that is, the ocean loses heat; the second phase has a positive heat balance, ie, the ocean has gained heat. The most balanced heat surveyed in the sea area is eastward greater than western.
