| Abstract: | By using optimal climate normals, the seasonal and monthly temperature and precipitation data of 160 Chinese meteorological stations during the period of 1995-1998 are examined. Results show that optimal climate nomals method performs well in temperature prediction, especially for winter. However, it is applicable only in certain areas and certain time periods in precipitation prediction. The performance of the seasonal forecasts is better than that of the monthly ones. Both the correlation coefficients between predicted and observed values and the average of the optimal climate normals are spatially continuous,and their distributions change with the time. |
