The 96 h typhoon track prediction experiments were carried out using medium range forecasting system of NMC by adding BOGUS typhoon into the first guess field or the analysis field in order to provide longer time typhoon track forecast.

The CLIPER model of typhoon track forecast at 6h intervals and 6h-72h over the Northwestern Pacific for occasion of ships at sea was proposed, based on statistical analysis of climatological and persistent characteristics about historic typhoon activities between 1949 and 1989.

Forecasting typhoon tracks applying the asymmetric structure thoery;

The search and analysis of the typhoon tracks data between 1949 and 1998 is introduced using the programming language Visual Basic.

After analyzing a great deal of typhoon data, the paper got the main typhoon tracks which caused serious storm surges at the Yangshan port.

In this paper, the adjoint method is applied to the statistical-dynamic model (SD-90) for the prediction of typhoon tracks along with the regularization thinking and optimal control techniques.

Projected by the directions of thermal gradient force with current typhoon movement,the changes of the typhoon move is studied to obtain a simple and feasible method for the forecasting of typhoon path.
