ABSTRACT maximum wind speed near the typhoon center is 33 m/s, pressure near the typhoon center is 975 hpa, In August 2 Typhoon "Damrey" has At 9 am. on Aug.,2,2012, the most severe typhoon ‘DAMREY’ landed on Chenjiagang town in Xiangshui county in Province. landed north of the Yangtze River since 1949, has landed on Chenjiagang town in Xiangshui county in Jiangsu Province.

On July 28 2012, Typhoon "Damrey" generated at 25.7ºN, 147.4ºE which is about 1330 km far away from Fig.1 the tracks of typhoon "Damrey" Tokyo in Japan in the Northwest Pacific Ocean, which maximum wind . speed is 18 m/s . Pressure near the typhoon center is 1000 hpa. In August 1, "Damrey" strengthened to typhoon in the southeast ocean area of Kyushu in Japan, which centre is located at 30.1ºN, 132.2ºE far about 1330 km from Rizhao city in province. At am 10 the
