Abstract. The eastern Yellow Sea meteotsunami occurrences between 2010 and 2019 and guidelines derived using favourable conditions of pressure disturbance (10 min rate of air pressure change) for meteotsunami generation are described. A total of 34 meteotsunami events over the past decade can be classified based on a current meteotsunami monitoring and observation system. 1 min intervals of mean sea level pressure and sea level observations from 89 meteorological stations and 16 tide gauges are analysed. Most of the classified meteotsunami events (76 %, 26/34) in the eastern Yellow Sea are found to be between February and June during the winter-to-summer transition, which shows a strong seasonal trend. The meteotsunami occurrences are spatially frequent at the DaeHeuksando (DH) tide gauge, known as a beacon tide gauge of the observation system. It appears that the specific characteristics (intensity, occurrence rate, and propagation) of the pressure disturbance are in common on extreme meteotsunami events that are classified by applying the hazardous meteotsunami conditions among the 34 events. For a risk level assessment of the eastern Yellow Sea meteotsunami occurrences, favourable conditions of the pressure disturbance for meteotsunami generation are utilized. Overall, this study can provide useful and practical guidelines such as operation period, potential hot spot, and risk level to monitoring system operators when operating the monitoring system of the Yellow Sea.

过去十年（2010-2019年）黄海东部压力海暴发生的事件：监测准则

摘要。描述了2010年至2019年期间黄海东部发生的海啸和使用有利的压力扰动条件（气压变化速率为10分钟）来产生海啸的准则。过去十年中，根据当前的气象海啸监测和观测系统，总共可以分类34次气象海啸事件。分析了来自89个气象站和16个潮汐仪的平均海平面压力和海平面观测值的1分钟间隔。在黄海东部，大多数分类的气象海啸事件（76％，26/34）被发现是在冬夏过渡期间的2月至6月之间，这显示出强烈的季节性趋势。在DaeHeuksando（DH）潮汐仪上，气象海啸发生在空间上很频繁，这是观测系统的信标潮汐仪。看起来，压力扰动的特定特征（强度，发生率和传播）在极端的海啸事件中是共有的，这些极端事件是通过在34个事件中应用危险的海啸条件来分类的。为了对东部黄海发生的海啸进行风险等级评估，利用了有利于产生海啸的压力扰动条件。总体而言，这项研究可以为操作黄海监视系统的监视系统操作人员提供有用且实用的指南，例如操作时间，潜在热点和风险级别。在极端的海啸事件中，压力扰动和传播是很常见的，这些极端事件是通过在34个事件中应用危险的海啸条件进行分类的。为了对东部黄海发生的海啸进行风险等级评估，利用了有利于产生海啸的压力扰动条件。总体而言，这项研究可以为操作黄海监视系统的监视系统操作人员提供有用且实用的指南，例如操作时间，潜在热点和风险级别。在极端的海啸事件中，压力扰动和传播是很常见的，这些极端事件是通过在34个事件中应用危险的海啸条件进行分类的。为了对东部黄海发生的海啸进行风险等级评估，利用了有利于产生海啸的压力扰动条件。总体而言，这项研究可以为操作黄海监视系统的监视系统操作人员提供有用且实用的指南，例如操作时间，潜在热点和风险级别。
