中尺度业务数值预报试验模式系统原理和应用（一）系统概述、模式方程组及数值处理

The Principal and Application of the Mesoscale Operational Numerical Forecasting Experiment Model System Part ⅠSystem Introduction,equations and numerical treatment of the model

根据业务预报试验的要求、资料来源的特点及计算机条件，以引进的ＰＳＵ／ＮＣＡＲ中尺度模式系统的开发、修改为基础，配套开发研制了一系列辅助子系统，在ＶＡＸ小型计算机上形成了一套完整的“中尺度业务数值预报试验模式系统”，并进行了初步试验。本文是该模式系统的原理和应用试验结果。

In accordance with demands of operational experiment,data source and computercondition,on the basis of PUS/NCARMESOSCALLE MODEL,we stuDIED and madea a series of subsystems ,and using VA×4400 ,a mesoscale operational numerical forecasting model sys-tem was formed. some experiments were carried out.
