感热和潜热通量的最大差异约为 30 W/m 2 ，一月份潜热通量的平均值为 22.27 W/m 2 ，七月为 5.40 W/m 2 。对于显热，一月为 2.82 W/m 2 ，七月为 5.64 W/m 2 。我们表明，净辐射通量的最大差异可高达 55 W/m 2 ，一月份净 SW 的平均差异为 6.31 W/m 2 ，净 LW 的平均差异为 12.14 W/m 2 。 7 月份，SW 的差异为 29.99 W/m 2 ，LW 的差异为 14.31 W/m 2 。通量与卫星得出的表面风速、总可降水量和云量之间的关系提供了对控制净热通量的主要过程的深入了解。本研究旨在对海洋-大气界面净热通量中仍然存在的不确定性进行估计。
maximum difference in sensible and latent heat fluxes can be about 30 W/m 2 , the mean values for latent heat fluxes are 22.27 W/m 2 for January and 5.40 W/m 2 for July. For sensible heat, they are 2.82 W/m 2 for January and 5.64 W/m 2 for July. We show that the maximum difference in net radiative fluxes can be as high as 55 W/m 2 , for January, the mean difference in net SW is 6.31 W/m 2 and in net LW it is 12.14 W/m 2 . For July, the respective differences are 29.99 W/m 2 for the SW and 14.31 W/m 2 for the LW. Relationships between the fluxes and satellite derived surface wind speed, total precipitable water, and cloud cover provide insight on the dominant processes that control the net heat flux. This study is intended to present an estimate of uncertainties that still exist in the net heat flux at the ocean-atmosphere interface.
