摘要:
選用美國國家環(huán)境預(yù)報中心的全球再分析風(fēng)場為驅(qū)動風(fēng)場,以WAVEWATCH Ⅲ海浪模式為基礎(chǔ),采用全球-西北太平洋-中國近海海區(qū)三層嵌套方案構(gòu)建了1990—2020年海浪再分析數(shù)據(jù)集;利用該數(shù)據(jù)集,分析了福建省近海海浪災(zāi)害強(qiáng)度和發(fā)生頻率,并計(jì)算了典型重現(xiàn)期的海浪波高。結(jié)果表明:福建省海域海浪有效波高分布具有明顯的季節(jié)變化;因?yàn)榈匦蔚挠绊懀_灣海峽中部區(qū)域的巨浪出現(xiàn)頻率高于其他區(qū)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.
