莱州湾风暴潮的形成与增水量评估

The Formation of the Storm Surge and the Assesment of Tidewfater in Laizhou Bay

运用昌邑市下营水文站和寿光市羊口水文站的资料,对莱州湾风暴潮的形成机制和影响系统进行了分析。结果发现:诱发莱州湾风暴潮的天气系统主要有热带气旋、温带气旋及冷锋。由于莱州湾特殊的地理构造和地形条件,风暴潮在爆发过程中,有3个比较明显的天气机制,即爆发前的东南大风、爆发中的东北大风及其持续时间、天文大潮。对风暴潮各阶段的增水量值进行了定量的估计。

Using data from Xiaying hydrological station in Changyi county and Yangkou hydrological station in Shouguang county,the influencing systems of the storm surge in Laizhou Bay is analysed.The results show:The main weather systems causing storm surge can be divided into three categories:Temperate cyclone;Tropical cyclone;Cold front.Because of the special geographic structure and landform,the formation mechanism of the storm surge is as follows.The early strong southeast wind;Continual strong northeast wind during it bursting;The high chronometric tide.Some meaning to forecast storm surge in Laizhou Bay is found.
