摘　　要：设计了一种将原ＭＭ４模式的均匀网格变换成非均匀网格的方案，构造了一套适合河北省特点的变网格预报模式，同时建立了一套可投入业务使用的变网格数值预报系统。最后通过对一次暴雨过程的模拟分析，证明变网格数值预报优于均匀网格数值预报。scheme for conversing uniform into nonuniform mesh in the MM4 model was designed. A inhomogeneous mesh version of the model fitting Hebei region was developed. Anumerical weather forecast system for operational use was established. Finally,with the simulation experiment of a heavy rain process,it is certified that the inhomogeneous mesh modelis better than the uniform mesh model.
