摘要
采用丹麦DHI的Mike21水动力计算模块建立浙江沿海二维潮位数学模型,结合全球天文潮位预报模型,根据1323号台风"菲特"的气象资料,模拟了该强台风在浙江省的风暴潮过程,并特别对造成历史最高水位的鳌江站的风暴潮位和增水过程进行了分析。计算结果表明:该站最高潮位和最大增水的模拟精度在10 cm左右,时间误差约10 min,模型在本海域的数值计算能够满足预报要求。
Based on the meteorological data of Typhoon 1323 ＂Fitow＂,a two-dimensional MIKE21 model of Zhejiang coastal tidal level with global astronomical tidal level forecasting model is established to simulate the storm surge and water level variation in Aojiang station during this strong typhoon.The calculation results show that the accuracy of the highest tide level and the largest water increase is about 10 cm,and the time error is about 10 min,which indicate that the model calculation is satisfied with the requirement of numerical forecasts in this area.
