摘要
采用北京气象中心五层原始方程业务模式,对三种不同的内边界条件进行了单向(one—way)自嵌套对比试验;对预报误差水平分布特征及在不同层次上的影响问题,进行了较为详细地考察和研究。并提出了一种改进的嵌套方案。
Control testa are carried out for three categories of numerical schemes to treat the lateral bounday conditions of aone-way nested model, which was originaily an operational 5-layer primitive equation model developed by the National Meteorological Center. The horizontal distribution of forecasting errors and the possible computational effects at different levets are examined in some detail Finally, an improved scheme for the treatment of the lateral boundaries is proposed.
