摘　　要：本文利用日本气象传真、云图和NCEP/NCAR再分析资料,分析了0724号台风"海贝思"异常路径的成因,发现其逆时针打转路径的形成主要与高低空不同方向的引导作用和双台风效应有关,南支槽东移并与西风槽合并是其东退的主要原因。从云图上,能明显的判别出台风周围大的环境场,从而可以利用云图预报台风的发展趋势。By using facsimiles of JMA, cloud images and NCEP/NCAR reanalysis data, the causes of abnormal track of typhoon 0724 ＂Hagibis＂ are analyzed. Results show that the binary tropical cyclone interactions and different direction steering flows of high-low levels played an important role in the formation of anti-clockwise rooting track. The eastward shift of southern branch trough mainly resulted in the eastward withdraw of ＂Hagibis＂. Large scale environmental fields were obviously recognized by analyzing the cloud images, so they can be used to forecast the developing tendency of typhoons.
