Four-year averages of 25-kilometer-resolution measurements of near-surface wind speed and direction over the global ocean from the QuikSCAT satellite radar scatterometer reveal the existence of surprisingly persistent small-scale features in the dynamically and thermodynamically important curl and divergence of the wind stress. Air-sea interaction over sea surface temperature fronts throughout the world ocean is evident in both the curl and divergence fields, as are the influences of islands and coastal mountains. Ocean currents such as the Gulf Stream generate distinctive patterns in the curl field. These previously unresolved features have important implications for oceanographic and air-sea interaction research.
从快速散射计卫星雷达散射仪获取的全球海洋近地表风速和风向的25公里分辨率测量数据的四年平均值显示，在风应力的动态和热力学重要涡度和散度中存在令人惊讶的持续小尺度特征。全球海洋海表面温度锋面的海气相互作用在涡度和散度场中都很明显，岛屿和沿海山脉的影响也是如此。诸如墨西哥湾流等洋流在涡度场中产生独特的模式。这些以前未解决的特征对海洋学和海气相互作用研究具有重要意义。
