【摘要】 <正> 一、前言广东省的粤西海岸屡遭台风和台风暴潮的袭击,是我国台风暴潮的多发区和重灾区之一,我国近百年来最严重的一次8007号特大台风暴潮就发生在该地区。本文从风暴潮二维全流方程组出发,采用交错网格和有限差分方法,并取圆形台风模式,对袭击粤西海岸的台风暴潮进行了有限差分数值模拟计算,获得了较为理想的结果。二、数学模式(一) 全流方程组和有限差分方程组假设本数值模拟计算海区(图1)的海水是不可压缩的流体,密度均匀且为一常数,更多还原

【Abstract】 The numerical prognosis models of typhoon surge along the southeast coast of China have been used for the calculations of 18 typhoon surges in the Western Guangdong Coast from which quite satifactory results have been gained. For the calculated and observed typhoon surges, 11 of them, accounting for 61.11%, are in good agreement both in surge curve pattern and peak values, 3 of them, accounting for 16.67%, have similar curve pattern but rather deviated peak values, 3 of them or 16.7% have similar peak values but differing curve pattern, only one of them, accounting for 5.56% are different in both.更多还原
