| 摘 要： | 基于历史数据的分析,选择历史上强度最强的台风"荷贝"作为设计超强台风的强度,最不利路径的台风"雪莉"作为设计路径,作为深圳香港海域设计超强台风。采用海洋-陆架区-海岸三重嵌套网格建立的天文潮-风暴潮-台风浪耦合模型计算设计超强台风遭遇天文大潮的高潮位登陆时深圳香港海域的可能最高潮位和浪高。计算结果表明,大鹏湾北部和香港吐露港内,可能最高风暴潮位在3.00 m以上,浪高达到4.0～5.0 m;香港维多利亚港风暴潮位2.92 m,深圳香港水域东部南部在2.50 m以上,浪高3.0～5.0 m。可能最高风暴潮位比大鹏湾防潮警戒水位高1.62 m左右,比香港维多利亚港200年一遇的潮位高0.50 m。

| Abstract: | The design super-typhoon is chosen considering the most intensity "Hope" and the worst track "Shirly" from the historical data in Shenzhen and Hong Kong Waters.The possible highest storm tide level and wave height are evaluated by the coupling model of the tide-storm-wave in three levels of nested geographic domains,ocean,continental and coastal,when the design super-typhoon is landing during the highest astronomic tide level.The computational results show that the possible highest storm tide level is more than 3.00 m in the north Mirs Bay and Tolo Harbor,and wave height is about 4.0-5.0 m;the maximum storm tide level is 2.92 m in the Victoria Harbor,and more than 2.50 m in the east and south in Shenzhen and Hong Kong Waters.The possible maximum storm water level is 1.62 m higher than the warning tide level in the Mirs Bay,and 0.50 m higher than 1 in 200 year tide level in Victoria Harbor. |
