Abstract

In recent years, strong typhoons have passed South Korea almost every year and severe damages were incurred directly and indirectly. However, instances where wave and wind data were procured from the offshore approach path of the typhoon are very rare and thus researchers are experiencing difficulties in obtaining calibration and verification data of typhoon-generated wave modeling. This paper provides a synthesis of records of observations by the Korea Meteorological Administration and Korea Institute of Ocean Science and Technology on storm waves generated by the typhoons SONGDA, NABI, and SHANSHAN that passed from 2004 to 2006 in order to help researchers interested in typhoon-generated wave numerical modeling. Although the trajectories of typhoon NABI and SHANSHAN were east of the Korea Strait, a significant wave height of 8.3 m was measured at Namhyeongjedo located east of Geojedo. Moreover, an unprecedented significant wave height of 12.2 m was measured for both typhoons at a station 1.4 km away from Yeongil Bay breakwater. Meanwhile, a comparative analysis of data obtained with a ocean data buoy at Geojedo and a Directional Waverider at Namhyeongjedo showed maximum wave heights that were similar but considerably different significant wave heights.

최근 우리나라에는 거의 매년 대형 태풍이 내습하였으며 이로 인해 직 간접적으로 많은 피해가 발생하였다. 그러나 태풍의 내습 시 태풍의 외해 진입경로에서 파랑 및 바람자료를 확보한 사례는 매우 드물며 이로 인해 태풍파 모델링의 보정 및 검증자료 확보에 어려움을 겪고 있는 실정이다. 본 논문은 기상청과 한국해양과학기술원에서 2004~2006년에 내습한 태풍 송다, 나비, 산산으로 인한 폭풍파들을 관측한 기록들을 종합하여 제공함으로써 태풍파 수치모델링 관련 연구자들에게 도움이 되도록 하였다. 태풍 나비와 산산의 진행경로가 대한해협보다 동쪽이었음에도 불구하고 거제도 동쪽에 위치한 남형제도에서 유의파고 8.3 m가 관측되었으며, 특히 영일만방파제 전면 1.4 km 지점에서는 두 태풍 모두 기록적인 유의파고 12.2 m가 관측되었다. 한편, 거제도의 해양기상부이와 남형제도의 파향 파고계로 취득된 자료들의 비교 결과 최대파고는 유사하였으나 유의파고는 상당한 차이를 나타냈다.
