摘　　要：利用2021年6月20日至7月23日在渤海中部海域2个站位开展的海浪同步观测实验获取的实测海浪资料,分析了该海域夏季的海浪统计特征,并利用该资料对渤海海域的海浪数值预报产品进行了对比检验,结果表明:观测海域2个站位的海浪要素整体趋势相似,海浪的主波向为SE-SSE向,跨零周期基本在5s以内,观测的有效波高最大约2m,2个站位出现最大波高的波向均为SE向,观测期间经历了2次明显的起浪过程,2个站位的有效波高在起浪过程中出现了差异,这可能与风区有关。通过对数值预报产品进行对比检验,表明在观测位置处的模拟效果良好,海浪特征参数的整体变化趋势与观测相符,预报数据可为海上工程作业提供参考。Based on the observed ocean wave data of the synchronous observation experiment conducted at two stations in the central area of the Bohai Sea from June 20 to July 23,2021,the statistical characteristics of waves in summer in this area are analyzed,and the numerical wave forecast products in the Bohai sea area are compared and verified through the observation data.The results show that the overall trend of the ocean wave elements at two observational stations is similar,the main wave direction is SE-SSE,and the cross-zero period is basically within 5 s,and the maximum significant wave height is approximately 2 m.The direction of the maximum wave height at both locations is from the SE.During the observational period,there are two obvious wave growth processes,and the significant wave heights at the two stations are different in these processes,which may be related to the wind fetch.The comparison of the numerical forecast products shows that the simulation result at the observation position is acceptable,the overall variation trend of wave characteristic parameters is consistent with the observation.The numerical forecast data can provide reference for offshore engineering operations.
