Abstract: Based on the real-time wave measurement results of Dapeng Bay from 2014 to 2020, this paper presents a statistical analysis of the basic feature of waves in the observed sea area and their relationship with tropical cyclone activity. The results show that the significant wave height (SWH) under 1.0 m covers 95.94% of the observational period, and the wave characteristics of each station have obvious differences. The SWH above 1.0 m at Dameisha station mainly occurs in the boreal Autumn and Winter, which is dominated by the northeast monsoon. The SWH above 1.0 m at Xiasha station mainly occurs in boreal Summer and Autumn, which is modified by the southwest monsoon. While the SWH above 1.0 m at Wankou station mainly occurs in boreal summer, autumn, and winter, which is responded to the southwest and northeast monsoon synchronously. Due to the effect of tropical cyclones, the normal wave directions of each station are SE, S, and SSE respectively, while the the direction of intensified wave are SE, S/SW, and SSE separately. The analysis of the relationship between SWH and wind speed at the buoy positions during No.1713 Typhoon “Hato” suggests that the wind speed and SWH increase gradually with the approach of the typhoon. The peak of SWH slightly lags to the peak of wind speed, as well as the significant wave period prominently increased during the typhoon.
