中尺度数值模式(MM5V3)在沈阳区域气象中心的试用

简单介绍了沈阳区域气象中心在微机上调试和试用中尺度数值模式MM5V3的情况，MM5V3在前、后处理上使用Fortran90编程，与MM5V2有一定差别，利用T106L19资料和常规探空报形成经、纬网格的初值，预处理场和侧边界，代入模式前处理系统中，模式运行完毕后，预报产品直接进入MICAPS、Vis5d、Grads系统，进行图形显示，在2000年汛期试用中发现，MM5V3对东北地区的强降水过程有一定的预报能力，预报评分表明，MM5V3的降水预报结果和MM5V2互有优劣，总体来看，MM5V3的预报质量略高于MM5V2。

Application of the Mesoscale Numerical Model (MM5V3) in Shenyang Regional Meteorological Center

The mesoscale numerical model (MM5V3) was used on the personal computer in Shenyang Regional Meteorological Center. There are some differences between MM5V3 and MM5V2 when MM5V3 was compiled by Fortran 90 in its pre process and post process. The longitudinal and latitudinal grid data set of the initial field and the boundary was created by T106L19 and sounding data set. The outputs of prediction were joined with plotting systems of Vis5d and Grads. The results of MM5V3 are better than those of MM5V2 which had been used in 2000 flood season, but not all.
