Coastal storms as extreme hydrometeorological events have severe impacts on the coasts and consequently affect the coastal communities, attracting considerable research interest nowadays. Attempting to understand the risk of these extreme events, a coastal storm analysis is accomplished by studying the parameters which define a coastal storm and their properties, such as the wave height, the wave period, the duration, the calm period, and the storm energy. The frequency of occurrence of coastal storms, the thresholds of storm parameters and the way they are interrelating with each other draw a rough outline of wave climate during coastal storm events for a specific location. This information is valuable afterwards for the design of coastal structures and the coastal zone management. In this work, buoy datasets from 30 locations in the Mediterranean Sea are analysed for describing coastal storm activity. A sample of 4008 coastal storms is identified. Each location faces around 10–14 coastal storms per year, with most of them to occur in winter months and their characteristics to be site-dependent. Their average duration is lower than 30 hours, and 25% of them are consecutive events which hit the same location in less than a day. Furthermore, the wave period and the main direction present no remarkable fluctuations during a coastal storm. With this analysis, a deeper understanding of coastal storm severity is pursued, gaining knowledge about their past activity, in order to be prepared in the future and to protect the coastal areas.

地中海沿海风暴的统计分析

沿海风暴是极端的水文气象事件,对海岸造成了严重影响,因此影响了沿海社区,引起了当今的研究兴趣。为了了解这些极端事件的风险,通过研究定义海岸风暴及其参数的参数(例如,波浪高度,波浪周期,持续时间,平静期和风暴能量)来完成海岸风暴分析。 。沿海风暴的发生频率,风暴参数的阈值以及它们相互之间的联系方式,为特定地点的沿海风暴事件绘制了波状气候的粗略轮廓。此信息对于以后的海岸结构设计和海岸带管理非常有价值。在这项工作中,分析了来自地中海30个地点的浮标数据集,以描述沿海风暴活动。确定了4008例沿海风暴的样本。每个地点每年大约要面对10-14次沿海风暴,其中大部分发生在冬季,而且其特征取决于地点。它们的平均持续时间不到30小时,其中25%是连续的事件,不到一天就击中了同一位置。此外,在沿海风暴期间,波浪周期和主方向没有明显的波动。通过这种分析,人们对沿海风暴的严重性有了更深入的了解,获得了有关其过去活动的知识,以便为将来做好准备并保护沿海地区。每个地点每年大约要面对10-14次沿海风暴,其中大部分发生在冬季,而且其特征取决于地点。它们的平均持续时间不到30小时,其中25%是连续的事件,不到一天就击中了同一位置。此外,在沿海风暴期间,波浪周期和主方向没有明显的波动。通过这种分析,人们对沿海风暴的严重性有了更深入的了解,获得了有关其过去活动的知识,以便为将来做好准备并保护沿海地区。每个地点每年大约要面对10-14次沿海风暴,其中大部分发生在冬季,而且其特征取决于地点。它们的平均持续时间不到30小时,其中25%是连续的事件,不到一天就击中了同一位置。此外,在沿海风暴期间,波浪周期和主方向没有明显的波动。通过这种分析,人们对沿海风暴的严重性有了更深入的了解,获得了有关其过去活动的知识,以便为将来做好准备并保护沿海地区。其中25%是连续的事件,不到一天就击中了同一位置。此外,在沿海风暴期间,波浪周期和主方向没有明显的波动。通过这种分析,人们对沿海风暴的严重性有了更深入的了解,获得了有关其过去活动的知识,以便为将来做好准备并保护沿海地区。其中25%是连续的事件,不到一天就击中了同一位置。此外,在沿海风暴期间,波浪周期和主方向没有明显的波动。通过这种分析,人们对沿海风暴的严重性有了更深入的了解,获得了有关其过去活动的知识,以便为将来做好准备并保护沿海地区。
