飓风风暴潮受若干因素影响，包括风力强度、表面压力、前进速度、大小、接近角度、洋底深度和坡度、海岸线的形状和地理特征。每个因素的相对影响可能会被飓风接近陆地时作用的其他因素放大或减弱。为了解风强度、海面气压和前进速度对风暴潮的单独和联合影响，利用ADCIRC + SWAN（Advanced CIRCulation + Simulating Waves Nearshore）软件对Rita飓风风暴潮进行了后报试验。海洋气象公司（Ocean Weather Inc.）(OWI)作为ADCIRC + SWAN中的基本气象强迫。所有参数都与OWI风场中的参数有一定的百分比变化。模拟结果进行了分析，最大风强度，风矢量模式，最小表面压力，前进速度，最大水位，站水位时间序列，和高水位标记。不同情况下的结果相互比较，以及与观测数据。风强度的变化影响最大，其次是前进速度和表面压力。风强度和前进速度的组合效应与其单独效应明显不同。
Hurricane storm surges are influenced by several factors, including wind intensity, surface pressure, forward speed, size, angle of approach, ocean bottom depth and slope, shape and geographical features of the coastline. The relative influence of each factor may be amplified or abated by other factors that are acting at the time of the hurricane’s approach to the land. To understand the individual and combined influence of wind intensity, surface pressure and forward speed, a numerical experiment is conducted using Advanced CIRCulation + Simulating Waves Nearshore (ADCIRC + SWAN) by performing hindcasts of Hurricane Rita storm surges. The wind field generated by Ocean Weather Inc. (OWI) is used as the base meteorological forcing in ADCIRC + SWAN. All parameters are varied by certain percentages from those in the OWI wind field. Simulation results are analyzed for maximum wind intensity, wind vector pattern, minimum surface pressure, forward speed, maximum water elevation, station water elevation time series, and high water marks. The results for different cases are compared against each other, as well as with observed data. Changes in the wind intensity have the greatest impact, followed by the forward speed and surface pressure. The combined effects of the wind intensity and forward speed are noticeably different than their individual effects.
