| 摘 要： | 本文为应用正压原始方程作数值预报的初步试验。采用时间空间中央差分进行数值求解。通过试验确定了一种简单可用的边界条件及初始条件。 应用此方案对四个天气实例进行了24小时预报。计算结果尚好。对这四个实例中所包括的正压天气过程一般能较好的反映出来。

| Abstract: | The numerical predictions for northern hemisphere by the primitive barotropic equations are tested in this paper. The finite difference scheme for centered differences in space and time is adopted. The boundary condition is fixed in such a way that along the boundary the heights are assumed to be invariable with time, and the winds vanish. The initial wind fields are determined by the geostraphic approximation and Kibel's second geostrophic approximation. Four actual weather forecasts Eor 24 hours are presented. The results show that in general the barotropic processes in these examples are forecasted. |
