| 摘 要： | 首先运用COHEREN S三维多功能大陆架水动力学模型,对渤海四个主要分潮进行了调和分析,建立了渤海天文潮预报模型。结合9712号热带风暴的路径记录资料,运用风场、气压场估算公式,估算了风暴所经地带风场、气压场的变化过程。以此为输入条件,运用COHEREN S模型模拟了9712号热带风暴作用下渤海的增水过程,还模拟讨论了底摩阻系数对水位的影响。

| Abstract: | The 3-D COHERENS(A Coupled Hydrodynamical-Ecological Model for Regional and Shelf Seas) model is used to carry out analysis of the main four astronomic tidal constituents(M2,S2,K1,O1) in the Bohai Sea.Consequently an astronomic tide prediction model for Bohai Sea is established.Formula method is used to estimate the distributions of atmospheric pressure and wind speed over the sea region and the results are introduced into COHERENS model as input data.Process of water level setup influenced by the 9712 tropical storm is simulated by the established model.The modeled results of water surface elevation at Tanggu and Qinhuangdao tidal gauge stations are compared with the measured ones.Also the effect of the bottom coefficient to the water surface elevation is discussed. |
