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.

• 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。
