摘要
为研究中广核阳江海上风电场海域的海浪特征,利用2018年9月—2019年8月的海上实测资料,对海浪的季节变化特征、波高-周期联合分布、波高-波向联合分布、台风浪等分别进行了统计、分析和研究。结果表明:该海域主要受西南季风、热带气旋、东北季风三种天气系统影响,海浪类型以风浪为主,涌浪出现频率很小;常浪向为E向,强浪向为WSW向(主要由热带气旋造成);在东北季风的影响下,冬半年(10月—翌年2月)的平均波高大于夏半年(3—9月)的平均波高;受热带气旋影响,秋季波高最大,其中1822号台风“山竹”期间观测到14.7 m的最大波高。研究结果为海上风电综合利用平台研养殖试验研究提供重要的海洋动力基础资料。
In situ observation wave data in the offshore wind farm of CGN Yangjiang Offshore Wind Power Co.Ltd.from September 2018 to August 2019 were used to study the wave characteristics,including seasonal variation,wave height-period joint distribution,wave height-direction joint distribution and typhoon waves.The result are as follows:1)This sea area is mainly affected by southwest monsoon in summer,tropical cyclone and northeast monsoon in winter;2)The main wave type is wind wave with small frequency of surge waves;3)The dominant wave direction is E direction,and the largest waves occur in the WSW direction under the influence of tropical cyclone;4)The average wave height in the winter half of the year—period from October to next February—is larger than that in the summer half of the year—period form March to September—under the influence of the winter monsoon;5)Under the influence of tropical cyclone,the average wave height in autumn is the largest,whereof the largest wave height of 14.7 m was observed during Typhoon 1822 Mangkhut.This study will provide basic information on marine dynamics for the mariculture experiment on the platform for comprehensive utilization of offshore wind power.
