使用气候学和风应力数据计算了北大西洋 33° 至 60° 和西经 40° 至 10° 之间北大西洋上层 500 m 的季节性热收支的贡献。在极锋附近，平流和扩散在季节性热收支中与海气热通量一样重要。相比之下，沿着亚速尔群岛和不列颠群岛之间的延伸线，季节性海气热通量主要通过热含量变化来平衡。因此，这里可以从热预算中推断出海气通量，误差仅为 23 W m−2，因为避免了平流和扩散估计中的大误差。该区域的推断通量与三个批量公式估计值进行了比较。
The contributions to the seasonal heat budget of the upper 500 m of the North Atlantic between 33° and 60° N and 40° and 10° W are calculated using climatology and wind‐stress data. Near the polar front, advection and diffusion are as important in the seasonal heat budget as the air‐sea heat fluxes. In contrast, along a line extending between the Azores and the British Isles the seasonal air‐sea heat fluxes are balanced primarily by heat‐content changes. Therefore, here, the air‐sea fluxes can be inferred from the heat budget with an error of only 23 W m−2 because the large errors in estimates of advection and diffusion are avoided. The inferred fluxes in this area are compared with three bulk‐formulae estimates.
