| Abstract: | The normal typhoon paths with 109 cases during the period from 1960 to 1979 have been analysed in this study.These paths are divided into 7 categories.The effect of the position and intensity of largescale wave on each category has been examined.It has been discovered,as a result,that this effect is rather evident.On the other hand,the teleconnection between different centers of anion does exist.A simple theoretical analysis indicates that the teleconnection is related to the propagation of wave energy.Thus,to predict comectly typhoon path,not only the steering flow of typhoon,but also,more significantly,the behavior of large-scale wave over the Northern Hemisphere must be taken into consideration. |
