Based on the observed data of Typhoon Bebinca from a large meteorological buoy station in the Beibu Gulf, the variation characteristics of wind waves during the transit of the typhoon are analyzed. The results indicate: The time history curve of typhoon wind speed shows a double peak distribution, and the wind speed in the eyewall area of the typhoon was the largest. The wind speeds in the front eyewall area was greater than that in the back eyewall area. The maximum wind speeds in the front eyewall and the back eyewall were 22.6 m/s and 20.8 m/s, respectively. Typhoon eye area had the smallest pressure and wind speed, the largest wave height and wave period. The maximum wind speed in the eye area was 2.7 m/s, the maximum wave height was 5.4 m and the maximum wave period was 5.5 s. The maximum of wave height lagged behind the maximum of wind speed, and the lag time was about 40 minutes. The wave heights outside the eye area of typhoon were positively correlated with wind speed. During the period of typhoon influence when it was through the south of the meteorological buoy station, both wind direction and wave direction rotated clockwise, and wind direction and wave direction 10minute maximum rotated 50° and 150°, respectively. The wind and wave were not in the same direction, and the average angle between them was 171°.
