| Abstract: |
| On basis of introduced splines, we design a new nonlinear dynamic statistical model and a method of retrieving the model. The model has been tested by the Kunming and the Mengzi local climate system that are construted with the monthly mean rainfall and temperature. The results indicate that the model can effectively simulate and forecast the climate evolution and that it has excelient stability so that there is relatively small difference between the Simulating accuracy and the forecasting accuracy. |
