摘　　要：选用美国国家环境预报中心的全球再分析风场为驱动风场,以WAVEWATCHⅢ海浪模式为基础,采用全球-西北太平洋-中国近海海区三层嵌套方案构建了1990—2020年海浪再分析数据集;利用该数据集,分析了福建省近海海浪灾害强度和发生频率,并计算了典型重现期的海浪波高。结果表明:福建省海域海浪有效波高分布具有明显的季节变化;因为地形的影响,台湾海峡中部区域的巨浪出现频率高于其他区域。Using the wind fields from Climate Forecast System Reanalysis,this paper analyzes the intensity and frequency of offshore wave disasters in Fujian Province,as well as the wave height in the typical return period.The results show that effective wave height in the coastal waters of Fujian Province has significant seasonal variation.Owing to topographic effect,the central Taiwan Strait areas have a higher frequency of huge waves in comparison with other areas.The analysis results can provide important references for coastal marine function zoning,site selection and design of large offshore construction projects,and marine disaster prevention and reduction.
