Abstract
A series of numerical experiments has been carried out to test the usefulness of the pseudospectral method for calculation of derivatives in spherical coordinates. The results indicate that the method is more accurate than a fourth‐order finite‐difference scheme for the same resolution, but the two methods are of comparable efficiency. Certain aspects of the filtering problems arising in numerical models are exposed and discussed.This publication has 11 references indexed in Scilit:
