Climatic feature of water vapor transport, which is closely related to precipitation in the middle latitudes around East Asia, is investigated using a reanalysis data in June and September. The maximum pole-ward water vapor transport is formed along the continental coast in June, although it is formed over the western Pacific Ocean in September. It is indicated that the water vapor is primary transported by the southwesterly low level wind due to the heat contrast between land and ocean in June. However, there are few studies about the water vapor transport in September. In this study, it reveals that almost 92% of the total amount of pole-ward water vapor is transported by typhoons in September 1998. It means that the climatic water vapor transport is primary formed by the Typhoon and greatly influenced on the atmospheric circulation around East Asia in September.
