| 摘 要： | 介绍了一个成熟的海啸数值模式-COMCOT模式.COMCOT模式是一个能够模拟海啸产生、传播和增水全过程的基于浅水波方程的有限差分模型.模型采用多层网格嵌套,根据海啸在不同区域的传播特点和要求,分别选用不同的分辨率和计算设置,从而兼顾了模式的精度和计算效率.利用此模式模拟了2006年12月26日台湾南部7.2级地震产生海啸波的传播情况,结果与两个潮位站的海啸波监测数据相吻合.

| Abstract: | In this paper, a mature numerical model for tsunami simulation is presented. COMCOT (Cornell Multi-grid Coupled Tsunami Model) is a tsunami modeling package, capable of simulating the entire lifespan of a tsunami, from its generation, propagation and runup/rundown in coastal regions. COMCOT was developed based on Shallow Water Equations (SWE) in Spherical Coordinates and Cartesian Coordinates using an explicit Leap-frog Finite Differencing Method. As a nested multi-grid model, it is feasible to adopt differ... |
