Abstract:Based on the measured wave data of Yangjiang sea area for one year(September 1,2021 to August 31,2022),the characteristics of wave parameters are statistically analyzed,and the correlation between wave parameters is fitted and analyzed by the least square method.The results show that:(1)The annual average significant wave height is 0.82 m,the annual average period is 3.8 s,the annual maximum wave height is 10.98 m occurs during the transit of typhoon"Ma-on"in August 2022.(2)The study area is dominated by light waves,accounting for 74.15%;the normal wave direction is SE,the secondary normal wave direction is ESE and SSE;and the strong wave direction is ESE;the signifi-cant wave period is mainly 4~8 s;the normal wave direction is dominated by light waves with a period of 4~8 s.(3)There is a good linear correlation between characteristic wave heights.(4)During the transit of typhoon"Ma-on",the wave spectrum is dominated by double peak spectrum,with the maxi-mum spectrum peak of 53.79 m2/Hz and the corresponding spectrum peak frequency of 0.18 s.
