THE EFFECT OF THE TYPHOON DYNAMICS PROCESS (CISK) TO ITS MOVING

The influence of the typhoon dynamics has been studied based on theoretic research and practical computations in this paper. The results indicate that the CISK perturbance usually has dynamics moving velocity northwestward over Northwestern Pacific. Practical show that the typhoon dynamics moving velocity can approach 1/3 of the mean moving velocity of typhoons and it may be more sometimes. Therefore, the forecasting accuracy will be obviously improved to good if the dynamics moving velocity of typhoon indicated in this paper is considered. Particularly, the typhoon dynamics moving velocity is more important to forecast the difficult and complicated track of typhoon.
