摘　　要：该文基于ELCIRC(3D Eulerian-Lagrangian Circulation)海洋模型建立了一套适合黄渤海高分辨率的温带风暴潮数值预报模式。该模式基于非结构三角形网格,对岸形的刻画具有较好的能力;利用该模式对2009年2次显著温带风暴潮过程进行了分析与数值模拟,将模拟结果与受影响的几个验潮站的实测数据进行了对比;对比结果表明:所建立的高分辨率预报模式后报效果总体良好;对模式中存在的问题以及造成误差的因素进行了分析说明。In this paper, two typical extratropical storm surges occurring in 2009 were analyzed and simulated with a high resolution numerical forecasting model of extratropical storm surge for Bohai and Yellow sea. The model is built based on unstructured meshes. It can fit coastline better. Comparison of the model results with observations indicates that, the model is satisfactory basically.Some analysis are made in the paper for the causes leading to errors of the model.
