摘　　要：在阳江近海海域布置测站进行波浪现场观测,对采集到的2016年6月至2017年5月的实测波浪数据进行特性分析研究。结果表明,周年观测期间,观测海域波浪1/10大波波高平均值和最大值分别为1.18 m和6.54 m,有效波高平均值和最大值分别为0.94 m和5.31 m,平均周期为4.3 s,最大一次波浪过程发生在台风“莎莉嘉”过境期间;波浪以轻浪为主,各月均有中、大浪发生;常浪向和强浪向均为ESE向;特征波高之间、特征周期之间、特征波高和特征周期之间存在一定的转换关系。An observation station was set up in the offshore area of Yangjiang for wave field observation,and the collected measured wave data from June 2016 to May 2017 were analyzed and studied.The results show that during the annual observation period,the average and maximum wave height of 1/10 large waves are 1.18 m and 6.54 m,the average and maximum significant wave height are 0.94 m and 5.31 m,and the average period is 4.3 s.The largest wave process was caused by Typhoon Sarika.In this study area,the slight sea appeared the most frequently,and the moderate sea and rough sea occasionally presented monthly.Both the constant wave direction and the strong wave direction were ESE.Moreover,the transformations among characteristic wave heights and characteristic wave periods were obtained.
