The New Operational Numerical Prediction System of Shanghai Regional Meteorological Center and Preliminary Analysis of Operational Results

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 cycle 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.
