摘要
利用1958—2007年间的月平均SODA资料,较系统地研究了北太平洋经向热输送的基本特征和季节变化,并探讨了热输送季节变化的可能原因。结果表明,北太平洋经向净热输送的季节变化具有明显的区域性特征,在14°N以南海域热输送的季节变化较显著,而在14°N以北海域则较小;北太平洋经向净热输送的季节变化在很大程度上是由同一纬度上Ekman热输送和中东太平洋经向热输送的季节变化引起的。
Based on monthly mean SODA（Simple Ocean Data Assimilation） data （1958-2007）, the major features and seasonal variation of the North Pacific meridional net heat transport are systematically studied, and the possible causes for the seasonal variation are discussed in this study. The analysis results show that the seasonal variation of the North Pacific meridional net heat transport obviously has its regional characteristics. The heat transport seasonality becomes stronger in the south of 14°N than in the north. The causes for the seasonal variation of the North Pacific meridional net heat transport is associated with the seasonal variation of the Ekman heat transport and the central east ern Pacific meridional heat transport in the same latitudes.
