摘要
提出了两种在有限区域内进行2-维谱展开的方法。其中一个适用于直角坐标,一个适用于球面坐标。还对用这两种方法解 Helmholtz 方程的问题进行了讨论。
Two methods of expanding a scalar meteorological element in a limited-area were proposed.One is applicable to the rectangular coordinates,and the other to the spherical coordinates.Also,the problem how to solve the Helmholtz equation in the two coordinates with the methods was dis-cussed.
