风暴潮三维数值计算模式的研究及在渤海湾的应用
Research on 3-D numerical calculation model of storm surge and application in the Bohai Bay
摘要
Abstract
This study is based on the 2-D numerical model of extratropical storm surge in our laboratory. The astronomical tidal force and wind stress were considerd as the main factors when we built the 3-D numerical model of storm surge. The model derives three-dimensional storm surge mathematical model equations and applies ADI (Alternating Direction Implicit) method to discretizc and solve governing equations. To deal with the lateral boundary, the method of local-deepening and water range reducing were considered in the model. In the numerical calculation of extratropical storm surge, the numerical model of quasi-three-dimensional was applied, and then non-planar depth division model and planar equal depth distribution model were introduced and used in Bohai Bay for the computing of storm surge which occurred May 8 to 10, 2009. The comparison between the observed value of Tanggu tidal station and the calculated results of storm surge tidal level and setup level showed that the computed values which affected by astronomical tidal force and the wind stress are in good agreement with the measured data. According to the analysis, the results of the planar equal depth distribution model are closer to the practical situation than those of the non-planar depth division model, and it supplies theoretical basis for storm surge forecasting.关键词
