利用COADS资料分析了北方太平洋海气热通量的季节、年际和年代际变化。结果表明，北太平洋海洋表面夏季增热，冬季散失，净热损失达到最大值，尤其是黑潮延伸体。在副热带西风带、冬季成水区和夏季热带净热损失区，Q净的年变化主要取决于Qlat和Qsen的年变化，无论冬、夏季，Q净的低频信号主要是年变化和年代际变化。夏季Q网低频变化中心位于热带，冬季则位于黑潮延伸区。冬季东太平洋净Q值的年变化与西太平洋相反。净Q的年变化在北太平洋中部达到最大值。夏季，Q净的年变化在北太平洋中部达到最大值。夏季，Q净的年变化在热带太平洋达到最大值，沿赤道沿着呈偶极子分布。
Seasonal, annual and decadal variations of air-sea heat-fluxes over the Northern Pacific, ocean are analyzed based on the COADS dataset. The result shows that in North Pacific, ocean surface gains heat in summer and loses heat in winter, the net heat loss reaches its maximum, especially in Kuroshio Extension. In the subtropical western mode, water formation region in winter and the net heat lost zone in tropic in summer,the annual variation of Q net depends mainly on the annual variation of Q lat and Q sen. In both of winter and summer, low-frequency signal of Q net is mainly annual and decadal variations. In summer, the center of low-frequency variation of Q net is in tropic, while in winter it is in Kuroshio Extension. In winter, the annual variation of Q net in Eastern Pacific is opposite to that in western Pacific. The annual variation of Q net reaches its maximum in the central North Pacific. In summer, the annual variation of Q net reaches its maximum in the central North Pacific. In summer, the annual variation of Q net reaches its maximum in the tropical Pacific and has a dipole distribution pattern along the equator.
