| 摘 要： | 利用ＣＯＡＤＳ资料，首先计算了１９４９－１９７９年逐月北太平洋洋面的潜热通量与感热通量之和，并进行ＥＯＦ分解，然后分析它们的时空变化特征。结果表明：１、在北太平洋，季平均热通值的季节变化具有两种形式，而且主要决定于风速值的季节变化，尤以东亚季风的效应为最明显。２、暖池区全年平均的多年月平均热通量及其标准差都居北太平洋诸洋流区之首。３、北太平洋异常热通量场具有最重要的两种类型。１月异常热通量主要类型

| Abstract: | The COADS data are used to estimate the sum of monthly latent and sensible heat fluxes (simplified as head flux hereafter) over the sea surface in the North Pacific from 1949 to 1979. Then their time and space variations are analyzed using the EOF method. The results show that there are two patterns of the seasonal variations of heat flux in the North pacific, which are mainly affected by the sea sonal variation of wind speed, especially the East Asia monsoon, that the mean heat flux and corresponding standard variation over warm pool areas are prominant over those in other strong ocean current areas, and that two main types rel ated to the air-sea interaction can be distinguished from the anomalous heat flux in the North pacific. In addition, the interannual fluctuations of the principal patterns of allomalous heat flux in January are induced by the latitudinal fluctuations of the Aleutian Low and those in other seasons reveal marked sudden changes. |
