摘要：

渤海是我国的北方内海,海洋捕捞、海上航运、石油平台等海洋生产活动频繁,几乎每年都有由灾害性海浪引起的海难事件发生,造成较大的经济损失和人员伤亡。利用渤海周边10个波浪观测站40余年的海浪观测资料,进行了灾害性海浪特征分析和海浪致灾原因分析,给出了渤海灾害性海浪的时、空变化和分布特征,并对海浪灾害致灾原因进行天气学分析。结果表明:渤海灾害性海浪季节和区域特征明显,冬季多发于渤海海峡和莱州湾,一般强度较强;夏季多发于辽东湾和渤海湾,强度较弱。

The Bohai Sea is an internal sea, with high frequent activities such as marine fishing, transportation, and petroleum development. Therefore, the disastrous waves are extremely dangerous and cause large economic losses and casualties almost every year in this area. Based on the 40-year length wave in situ data at 10 observational stations in the Bohai Sea, the characteristics of the disastrous waves are analyzed. Moreover, the contributions of synoptic situation to the disastrous waves are analyzed. The analysis results show that the seasonal and regional characteristics of the disastrous waves in the Bohai Sea are significant. In winter, the disastrous waves occur frequently in the Laizhou Bay and the Bohai Strait, and the intensity is relatively strong. However, the disastrous waves mainly occur in the Liaodong Bay and the Bohai Bay with relatively weak intensity in summer.
