Abstract

Using the mesoscale coupled air-sea model, Typhoon Winnie (1997) is numerical simulated to investigated the impact of air-sea interaction on atmosphere. Compared with uncoupled model, the simulated results of typhoon intensity from coupled model become more realistic, with decreases in central pressure error of 2.3 hPa at 48 hr and 2.8 hPa at 72 hr. The air-sea interaction noticeably weakened the warm core of the typhoon. In the typhoon center, the air-sea interaction resulte in a temperature cooling of 3°C in the lower layer of the atmosphere and 2°C in the 500 to 600 hPa layers. In the mean time, the relative humidity can be decreased by 10 to 30%. Furthermore, the air-sea interaction leads to change of the distribution of air temperature, wind field and precipitation near the sea surface.
