一、引言在研究沿岸大陆架上的风海流时,必须考虑海底摩擦和海面坡度的影响。对于水平海底的情况,已有一些研究工作。但是,对于倾斜海底的情况,要确定流速分布和海面坡度的解析式,却是一个较困难的问题,在文章[2]中,用小参数法研究了倾斜海底风海流问题解析解的构造,在文章[3]中,对于具有实际意义的一系列特殊海底倾角的海域,构造出相应边值问题的格林函数,并用逐次逼近法给出零阶逼近解。但是,未对流场进行分析,本文是这一研究工作的继续。在本文中,将对上述问题的逼近解,进行分析和讨论。实际计算验证了理论的正确性。计算结果揭示了线性倾斜陆架上定常风海流的一些特殊性质。
I. INTRODUCTION In studying the wind currents on the continental shelf along the coast, the influence of submarine friction and surface slope must be considered. There have been some research work on horizontal seabed. However, it is a difficult problem to determine the distribution of flow velocity and slope of the sea surface in the case of inclined seabed. In [2], we study the structure of the analytic solution for the sloping submarine wind flow using the small parameter method, In [3], for a series of sea areas with a special seafloor dip angle, we construct the Green’s function of the corresponding boundary value problem and give the zero-order approximation solution by successive approximation. However, no analysis of the flow field is made, which is the continuation of this research. In this paper, the approximate solutions of the above problems will be analyzed and discussed. The actual calculation verifies the correctness of the theory. The calculation results reveal some special properties of steady wind currents on linearly inclined shelves.
