“…The air pressure jump arrived at GN on 30 March 23:45 and it moved to KS and BA on 31 March 01:05 and 01:25, respectively (Figure a). The movement of the air pressure jump was also observed at other meteorological stations along the west coast of Korea and the estimated moving speed of the air pressure jump was about 24–28 m/s [ Choi et al ., ; Eom et al ., ]. The air pressure jump height, the pressure difference from minimum to maximum pressure, was about 4.2 hPa, and the air pressure jump passed a weather observation station within 7 min.…”

“…[] reproduced the long wave amplitude similar to the observation within the eastern part of the Yellow Sea; whereas, Eom et al . [] used the whole Yellow Sea as their two‐dimensional model domain. The long ocean wave was not observed in the north of 37°N, which implies that the long wave was possibly generated within our model domain or the amplitude of long waves was very small in the north of 37°N.…”

“…Eom et al . [] claimed that the traveling speed was 28 m/s, which was estimated from the AWS data on land and the synoptic weather charts.

Meteotsunami‐tide interactions and high‐frequency sea level oscillations in the eastern Yellow Sea

While an air pressure jump was moving southeastward over the shallow water region of the eastern Yellow Sea in March 2007, a long ocean wave (meteotsunami) was generated and amplified due to the Proudman resonance. The long wave arrived at the coast during high tide with wave amplitude of 1.4 m and seawater overflew seawalls and inundated the land. High-frequency sea level oscillations continued for 8-9 h after the long wave hit a local coast. The Moon's age was 12 days, and the tidal range was about 4 m between neap and spring tides. Two-dimensional numerical simulations were performed, to reproduce amplification of the long ocean wave in offshore and oscillations of sea level at the coast. Both tidal elevation and tidal currents were found to affect the growth of the long wave amplitude by the interactions between tides and the long wave. Long wave-tides interactions are important processes for the accurate prediction of long wave arrival time and maximum height and for the reduction of coastal hazards in the macrotidal region. After the long wave hit the coast of remote regions, reflected waves propagated radially from remote regions to a local coast. The high-frequency sea level oscillations at a local observation station continued, until all of the reflected waves from remote regions had passed by. It was concluded that high-frequency oscillations of sea level are generated not only by local reflection of the long wave, but also by propagation of the reflected waves from remote regions.
