It is found that the climatological mean of wind speed and air - sea humidity difference are both large , the variation of wind speed are almost in phase with air - sea humidity difference , yielding much larger or smaller latent heat flux . so the ocean release the most latent heat in its own winter of the two hemispheres when both wind speed and air - sea humidity difference are large 发现在南北两信风区，风速和海气湿度差的变化几乎是同位相的，平均背景风速和海气湿度差都较大，他们互相加强彼此对潜热通量变化的贡献，所以海洋潜热损失最大是发生信风南北两区的各自风速和海气湿度差都较大的冬季。
In trade wind regions , the biases in fluxes from the biases in algorithm are about 3 - 4 times of the biases in the fundamental flux - related variables and 1 - 2 times in equatorial regions . in the most area of tropical atlantic , the evaluation of magnitude and time series trends of flux in whoi are more accurate than ncep1 and ncep2 结果认为ncep1和ncep2产品中，由算法所带来的误差在信风区远远大于赤道区；在信风区，由算法所带来的误差是基本变量所带来的误差的3 - 4倍，在赤道区，为1 - 2倍。
