ABSTRACT

　　The relationship between thickness of two isobaric surfaces and Typhoon movement is discussed. The result says that Typhoons will move to the maximum thickness region. And, according to the re-analysis of 92 Typhoons which occured in the West Pacific, within the period from 1964 to 1971, we found that 500-700mb thickness is most favorable. Case studies are also presented, and approve the result except in which a cold front is approaching the same region.
