摘　　要：根据上海市气象局计算机资源配置情况，以ＮＣＡＲ－ＰＳＵ／ＭＭ４为模式框架，国家气象中心数值预报产品为依托，建立了上海区域气象中心业务数值预报新系统，更新原五层模式套网格业务系统．根据有无进入区域的热带气旋而分别执行热带气旋模式或有限域模式．近一年的运行表明，计算稳定，有较好的预报效果，同时增加了预报产品，可提供华东地区２５个主要城市每６小时一次的地面要素预报，供区域内省台调用．According to computer resources disposition in Shanghai Meteorological Bureau and numerical forecast products of National Meteorological Center, a new operational numerical prediction system of Shanghai regional Meteorological Center is set up with the model frame of NCAR PSU/MM4, and the former operational system of five level nested model is renewed. According to whether there is tropical cyclme or not getting to the domain, the typhoon model or limited area model is carried out, respectively. Through one year operation, it is shown that the computation of new operational system is of stability and there is a good prediction effect. In the meantime the forecast products, including the surface element predictions every 6 h for 25 cities in East China, can be provided for provincial meteorological Burean in the regional center.
