研究大陆架上的风海流,必须同时考虑海面坡度和海底地形(变水深)的影响。要想获得分析解是比较困难的。 作为对大陆架地形的一级近似,本文考虑线性变化的倾斜海底,岸边水深为零。并假定海岸线平行于地球经度线,考虑柯氏参数随纬度的变化,把这个β效应项——βy作为小参数,同时假定定常两维风场随纬度也是按小参数βy变化着。 The study of the wind currents on the continental shelf must take into account both the slope of the sea surface and the seafloor topography (variable depth). To obtain analytic solution is more difficult. As a first-order approximation to the continental shelf topography, this paper considers a linearly varying sloping seabed with zero depth on the shore. Assuming that the shoreline is parallel to the longitude line of the Earth, taking the change of Kor’spaw parameter as a function of latitude, we consider the β-effect term -βy as a small parameter and assume that the stationary two-dimensional wind field changes with the small parameter βy with latitude.
