一个赤道太平洋西部边界潜流广义扰动机理的近似解法

Approximate solving method for a generalized perturbed mechanism of western boundary undercurrents in equator pacific

研究了一类赤道太平洋西部边界潜流的摄动机理.考虑了对应的广义控制方程.首先引入了一个优化的同伦映射,利用相应的映射求得了原模型的近似解.最后,通过一个例子说明了用同伦映射方法得到的近似解具有较好的精确度.

A class of perturbation mechanisms for the western boundary undercurrents in the equator Pacific is considered. The generalized governing equations arc studied. Firstly, an optimal homotopic mapping is introduced. And the approximate solution is obtained for original model using the corresponding method of the homotopic mapping. Finally, an example shows that a good precision is altained for the approximate solution using the method of homotopic mapping.
