태풍의 이동속도에 따른 한국 남해안 폭풍해일고의 특성

국문 초록 (Abstract)

최근 기후변화에 의한 영향으로 태풍에 의한 피해가 점차 증가하고 있다. 이에 따라 폭풍해일의 특성을 결정하는 여러 요소에 대해 오랫동안 많은 연구가 수행되었으며, 대부분의 연관성들이 발견되었다. 폭풍해일은 여러 요소에 의해 복합적으로 결정되는 이유로 다른 결과를 보여주는 경우가 많아 연구마다 다른 결론을 내리는 경우가 많았다. 이런 이유로 태풍의 이동속도 변화에 의한 폭풍해일의 다양한 특성들을 이해하기 위해 본 연구를 수행하였다. 본 연구는 수치해석 프로그램을 이용하여 수행되었으며, 이동속도에 의한 영향을 분석하기 위해 다른 요소들을 최대한 단순화하였다. 수치해석 결과 태풍에 의한 폭풍해일은 이동속도가 빨라질 경우 점차 증가하는 경향을 보였다. 폭풍해일은 느린 이동속도에서는 넓고 완만하게 증가하였으며, 빠른 이동속도에서는 좁고 급하게 증가하는 형상을 보여주었다. 동일한 이동속도의 경우 실제 해역의 수심 영향이 폭풍해일에 크게 작용하는 것으로 판단된다. 제주도를 지나 이동속도가 변화하는 경우 남해안의 폭풍해일에 큰 영향을 미치지 못하는 것을 확인하였다.

The damage caused by typhoons is gradually increasing due to the climate change recently. Hence, many studies have been conducted over a long period of time on various factors that determine the characteristics of storm surge, and most of relationships have been discovered. Because storm surge is complexly determined by various factors, it often show different results and draw different conclusions. For this reason, this study was conducted to understand the various characteristics of storm surge caused by changes in the forward speed of typhoons. This study was carried out with a numerical model, and the effect of forward speed could be analyzed by simplifying other factors as much as possible. When forward speed is increased, storm surges caused by typhoons tended to increase gradually. The storm surge showed a wide and gentle increase at a slow speed, but a narrow and steep one at a fast speed. In the case of the same forward speed, it was found that the storm surge was significantly influenced by the water depth of actual sea area. It was confirmed that the change in forward speed after passing Jeju Island did not significant affect on the storm surge in the south coast of Korea.
