| Popis: | Cho, K.-H., Choi, J.-Y., Park, K.-S., Hyun, S.-K., Oh, Y. and Park, J.-Y., 2013. A synoptic study on tsunami-like sea level oscillations along the west coast of Korea using an unstructured-grid ocean model. Abnormal tsunami-like sea level oscillations were recorded along the west coast of Korea on March 29–31, 2007, and May 4, 2008. These oscillations had maximum amplitudes of 1.6 m and 1.4 m, respectively. Analysis of observation data revealed that sea level oscillations coincided with atmospheric pressure disturbances moving eastward over the Yellow Sea. The atmospheric pressure disturbance in 2007 was characterized by a 5.3 hPa air pressure jump at Yeonggwang whereas that in 2008 was characterized by a 2–3 hPa change at Boryeong. To understand the generation and amplification mechanisms of the two events, we carried out synoptic numerical experiments using a two-dimensional unstructured-grid ocean model. From analyses of weather radar images and weather charts, we estimated the direction and s... |
