Hurricane Fiona (2022)

Strong winds over water can cause the water level to rise. This storm surge can flood land, change the shape of beaches, and cause damage to roads and buildings. In this study, we use a computer model to calculate the storm surge during Hurricane Fiona, one of the most intense storms ever to hit eastern Canada. We use the model for different conditions, and determine that part of the storm surge was generated over the ocean, while another part was generated over the gulf. These two parts of the storm surge did not occur at exactly the same time, and were not coincident with high tide. If all three of these components of the total water level peak simultaneously in a future storm, coastal areas could experience even more damage.海面强风可引发水位抬升。此类风暴潮（storm surge）可引发沿海陆地洪涝、重塑海滩形态，并对道路与建筑造成损毁。本研究采用计算机模型，对袭击加拿大东部的最强风暴之一——飓风菲奥娜（Hurricane Fiona）期间的风暴潮进行模拟计算。本研究针对不同工况运行该模型，结果显示部分风暴潮生成于外海，其余部分则生成于海湾海域。该两部分风暴潮的出现时刻并不完全一致，且均未与高潮位重合。若未来某次风暴中，总水位峰值的这三个组成部分同时出现，沿海地区或将遭受更为严重的损毁。
