半Lagrange法在数值预报中的应用和近年来的发展(Ⅰ)

THE DEVELOPMENT OF THE SEMI - LAGRANGIAN TECHNIQUE AND ITS APPLICATIONS IN NWP IN RECENT YEARS

本文就五十年代以来半Lagrange法在数值预报中的应用和近年来的发展进行评述,介绍我国在这方面的工作。还就此法和Euler法的优缺点作了比较;指出了存在的问题。

The development of the semi-Lagrangian technique and its applications in NWP since the fifties have been reviewed, which include the research works made by Chinese meteorologists. Finally, a comparison between the Euler technique, their advan tages, shortcomings and the problems to be settled are given.
