摘要

摘要本研究从缅因州中部到佛罗里达州南部的 12 个美国国家海洋和大气管理局验潮站提取了 20 世纪初到 2022 年期间的历史水位数据,以确定美国大西洋沿岸的风暴频率和规模是否存在时空趋势。我们使用风暴侵蚀潜力指数(SEPI)来识别和量化风暴。然后,我们利用这些风暴的时间和规模,使用累积风暴影响指数(CSII)经验模型来确定风暴集群和大规模风暴对沙滩的累积影响。这项研究的结果表明:(1) 任何站点的风暴频率都没有明显增加(易受风暴潮增量影响的避风站点除外);(2) 12 个潮汐站点中有 8 个站点的风暴强度随时间的推移有显著的统计意义,但增幅不大;(3) 风暴强度(SEPI)和累积风暴影响(CSII)的区域差异,其特点是北部的外热带风暴 (时间集群)更频繁,而南部的热带风暴较不频繁;以及 (4) 区域海滩恢复期为 4 到 10 年。

Storm surge frequency, magnitude, and cumulative storm beach impact along the U.S. east coast
Abstract. This study extracted historical water level data from 12 National Oceanographic and Atmospheric Administration tide gauge stations, spanning the period from the early 20th century to 2022 from central Maine to southern Florida, in order to determine if temporal and spatial trends existed in frequency and magnitude of storms along the U.S. Atlantic Ocean coast. We used the Storm Erosion Potential Index (SEPI) to identify and quantify storms. We then use the timing and magnitude of those storms to determine the cumulative effect of storm clustering and large magnitude storms on sandy beaches using the cumulative storm impact index (CSII) empirical model. The results from this study showed (1) no appreciable increase in storm frequency at any of the stations (except for sheltered stations susceptible to storm tide augmentation); (2) statistically significant, but modest increases in storm magnitudes over time for eight of the 12 tidal stations; (3) regional differences in storm magnitudes (SEPI) and cumulative storm impacts (CSII) characteristic of more frequent extratropical storms (temporal clustering) in the north and less frequent tropical storms in the south; and (4) a four to 10 year recovery period for regional beach recovery.
