蓬莱海域的潮汐潮流特征分析

摘要

基于2007年10月的水文测验资料,分析了蓬莱海域沿岸东西两侧在不同潮波系统控制下的潮汐潮流变化特性.分析结果表明:蓬莱东岸属正规半日潮,蓬莱西岸属不正规半日混合潮,潮流的性质与潮汐不同,东、西两岸的潮流都为不正规半日混合潮流.潮波自北黄海经渤海口门以接近前进波的形态向渤海内传播.%Based on the hydrologic data of October 2007, the characteristics of tide and tidal currents in both east and west coasts of Penglai,controlled by different tidal wave systems,were analyzed in this paper.The analysis result indicates that the tide of east coast of Penglai is regular semidiurnal tide,while the tide of west coast of Penglai is irregular semidiurnal tide.The tidal current of east and west coasts of Penglai is also irregular semidiurnal current.Tidal wave,that is similar to progressive wave,propagates from the north Yellow Sea to Bohai Sea.
