摘要：
The one-dimensional numerical differentiation algorithm for periodical function is designed to calculating global atmosphere's vorticity using observational wind and the result is compared with that of the central difference method. The results show that the one-dimensional numerical differentiation algorithm is stable and feasible. Its accuracy is superior to the central difference method and it has stronger recognizing ability for the smaller-scale weather systems.
