Occurrence of pressure-forced meteotsunami events in the eastern Yellow Sea during 2010–2019
<p>This study examined the occurrence of meteotsunamis in the eastern Yellow Sea and the conceptual framework of a monitoring/warning system. Using 1 min intervals of mean-sea-level pressure and sea-level observations from 89 meteorological stations and 16 tide gauges between 2010 and 2019, a...

| description |
<p>This study examined the occurrence of meteotsunamis in
the eastern Yellow Sea and the conceptual framework of a monitoring/warning
system. Using 1 min intervals of mean-sea-level pressure and sea-level
observations from 89 meteorological stations and 16 tide gauges between 2010
and 2019, a total of 42 pressure-forced meteotsunami events were classified.
Most meteotsunamis (71 %) displayed a distinct seasonal pattern occurring
from March to June, and intense meteotsunamis typically occurred at harbor
tide gauges. The occurrence characteristics of the meteotsunamis were
examined to improve the meteotsunami monitoring/warning system. Air pressure
disturbances with speeds of 11–26 m s<span class="inline-formula"><sup>−1</sup></span> and NNW–SW directions were conducive to meteotsunami generation. Most meteotsunamis (88 %), as well as strong
meteotsunamis with a wave height exceeding 40 cm (19 %), had dominant
period bands of less than 30 min, containing the resonant periods of harbors
in the eastern Yellow Sea. Thus, the eastern Yellow Sea is a harbor-meteotsunami-dominated environment, characterized by frequent meteotsunami
occurrences and local amplification in multiple harbors. This study can
provide practical guidance on operation periods, potential hot spots, and
risk levels to monitoring/warning system operators in the eastern Yellow
Sea.</p> |
