利用卫星测高和海面温度数据估算了北大西洋西部表面涡流引起的热量扩散率。按照马歇尔和肖茨(1981)的想法，从总涡通量中去掉了旋转涡通量。由此产生的涡激扩散系数具有很大的空间变异性，在墨西哥湾流南面的S−1附近，在1-2×103m2的范围内，S−1在墨西哥湾流内部。
The eddy‐induced diffusivity for heat at the surface of the western North Atlantic Ocean is estimated using satellite altimetry and sea surface temperature data. A rotational eddy flux is removed from the total eddy flux following the ideas of Marshall and Shutts (1981). The resulting eddy‐induced diffusivity shows considerable spatial variability with a value near 104 m2 s−1 just to the south of the Gulf Stream and values in the range 1–2 × 103 m2 s−1 within the Gulf Stream itself.
