Abstract

　　This article was used as a statistical method to select thirty samples of typhoon which occurred from 1969 to 1976 in the western Pacific Ocean to the east of Taiwan. Its main purpose is to study the relationship between the change in cols formed by the sub-tropical highs on the 500mb chart and movement of typhoon. In addition, the K value is also selected as a forecasting factor in order to examine its possible relation with the directions of typhoon movement.
　　An analysis indicates that movement of typhoon has several different patterns. However, the relation between cols and the direction of typhoon movement could not be ascertained successfully for lack of reliable data.
　　Several cases are also studied so as to verify the fitness of the result.
