Abstract:According to the measured wave data from September 2018 to August 2019 in the sea area of western Guangdong,this paper mainly studied the characteristics of wave variation,and the joint dis-tribution of wave height and period and wave type distribution characteristics month by month.The differences in the wave spectrum for different typhoon waves were explored.The results showed that the maximum wave height was 14.7 m,which caused by typhoon"Mangkut",and the maximum monthly average significant wave height was 1.6 m in December.There were more wind waves in win-ter,and the swells accounted only 38%.While in other seasons,swells accounted for more than 60%.There were obvious differences in wave spectrum type,peak frequency and frequency range during the transit of typhoon"Mangkut"and"Baijat".The wave type was mixed wave,in which the swell and wind wave predominated respectively.The research results could provide references for marine disaster prevention and reduction,ocean environmental assessment and ocean engineering design.
