Abstract: The wind field data derived from satellite images which are provided by National Satellite Meteorological Center are led into the numerical weather prediction system of typhoon tracks at National Meteorological Center. Three experiments are done by using them in some cases. The first experiments is to correct the objective analysis wind field. The second one is to attain an asymmetric wind field of bogus vortex. In order to form more harmonic analysis field and asymmetric bogus vortex, mass field is modified based on the above mentioned two experiments. It is shown that the first one has an obvious improvement on the forecast of typhoon tracks; the second one also has some effective effect on the forecast of typhoon tracks; the modification of objective analysis field in the third one can further improve the forecastprecision.
