Abstract: A baroclinic typhoon mbdel with a moving triple-nested grid has been applied for marine environmental forecasts in the National Marine Environmental Forecasting Center of China. The governing equations of the model and the numerical methods have been described in the first part of this paper. An outline of the model grid,variational adjustment initialization and forecast experiments will be continued in the paper. The outmost region with coarse grids is fixed and the inner fine resolution regions follow the track of typhoon center. In the model,variables at the coarse and fine grids interact through two-way coupling. The equilibrium equation and the cu-equation, an idealized typhoon field and variational adjustment scheme are used for initialization of the typhoon model. Prediction results are improved by using a simple but effective data assimilation method in which the initial fields are adjusted by using a simple but effective data assimilation method in which the initial fields are adjusted by using the sixth hour's typhoon report and the week-constraint variational principle. Finally the results of the forecasts are shown in the paper. The statistics of the forecast errors show that the model has certain capability to predict typhoon tracks and gives good results for surface wind and pressure forecasts. And the typhoon model has been linked with a sea-wave model and satisfactory forecast for wave height has been gotten.
