Abstract:
In order to understand the efficiency of the mediumrange forecasting of T213 products in autumn, the synoptic verification to the products of T213 9 6h mediumterm numerical forecasting from Sep. to Nov. 2006,and some comparison s with the NWP of ECMWF and JAPAN model are made. The results show that three mod els all have a good performance in forecasting the largescale circulation of t h e high and middle latitudes. The product of ECMWF model is better in forecasting westerly index, the temperature of 850hPa and southern branch trough, while the product of JAPAN model plays an important role in process forecasting in 4—6 N ov., 2006. But with regard to the precision of the intensity, position and occurr ed time of the weather system, T213 model still has a way to go.
