摘要

本文针对2011年4月15日大连老虎滩海域发生的大幅度假潮现象,采用大连老虎滩验潮观测站及其周边验潮观测站的实时观测水位资料,分析了本次大幅度假潮现象的基本特征,探讨了本次假潮形成的初步原因。结果表明:本次假潮形成的振幅1最大达到90.01cm,震荡周期为9.8~10.4min,与老虎滩湾的固有震荡周期一致。本次假潮现象与地震、气象、风浪等因素无直接联系,初步推测认为大连老虎滩附近海域地质板块位移很可能是导致本次假潮现象的主要成因。
Seiche phenomenon is a common sea hydrological incident happens in many sea areas in global.Aimed to reveal the driving force of seiche phenomenon,which happened in Laohutan of Dalian in April 15,2011,the observed tidal data of Laohutan tidal observation station and near other stations were collected,firstly characteristics of the seiche phenomenon were analyzed based on these observed tidal data.Then the driving forces of the seiche phenomenon were discussed.The marine geological plate movement was deemed for the main force of this seiche phenomenon.
