摘　　要：根据粤西沿海4个海洋站潮位资料分析、讨论了"灿都"台风风暴潮特征;利用改进的Jelesnianski风场,并采用耦合天文潮模拟与非耦合天文潮两种方案,对1003号台风"灿都"进行模拟、分析,模拟结果显示:在改进的杰氏风场驱动下,两种预报结果误差都比较小,但耦合天文潮预报结果优于非耦合天文潮预报结果。This paper attempts to address the characteristics of storm surge based on data from four ocean stations in western Guangdong coastal areas;improved Jelesnianski wind field and the coupling and uncoupling astronomical tide mathematical model are used to simulate storm surge caused by the typhoon＂Chanthu＂.Simulation results showed that in the improved wind field,the results of two prediction errors were relatively small,drived by improved Jelesnianski wind field,but the coupling astronomical tide prediction results were better than forecast results of non-coupled astronomical tide.
