Abstract

Abstract

By utilizing the denser upper-air observations from the Okinawa region and the Japanese islands during August 17-23,1975,the structure of Typhoon 7507 formed in this area has been analysed.It has been indicated that the cyclonic tangential wind maximum occurred in the eastern sector of the typhoon and the strongest inflow occurred in the southern portion of the typhoon about 150 km away from the typhoon centre.There was a deep inflow layer below the 300 hPa level.The anticyclonic outflow was the strongest at 150 hPa and was located in the NE quadrant of the typhoon.The convergence mainly took place in the southern part of the typhoon,while the divergence occurred at the lower and middle levels in the northern sector of the typhoon.The pattern of vorticity and vertical motion field were characterized by the similar asymmetry.
