Abstract

The trend in appearance of storm waves on the east coast of Korea was investigated based on long-term wave data observed at six different stations. At the four wave stations of KIOST (Sokcho, Mukho, Hupo, and Jinha), no notable trend was found during the observation period with respect to the annual average and maximum values of the significant wave height. In addition, the annual number of the appearance of storm waves showed decreasing trend at the three stations except Jinha, where slightly increasing trend of the quantity was recognized. In contrast, at Donghea ocean data buoy of KMA, abruptly increasing trend was found for the annual average and maximum of the significant wave height and for the annual number of the appearance of storm waves as well, demonstrating lack of consistency in the observation data from Donghea buoy of KMA.

우리나라 동해안 6개 관측점에서 장기간 관측된 파랑자료를 이용하여 폭풍파의 출현 추세를 검토하였다. 한국해양과학기술원의 4개 정점(속초, 묵호, 후포, 진하)에서는 관측기간 동안 유의파고의 연별 평균값과 최대값의 주목할 만한 추세가 나타나지 않았다. 또한, 폭풍파의 연별 출현 횟수는 진하에서만 완만한 증가 추세가 나타났고 나머지 세 정점에서는 감소 추세를 보였다. 그러나 기상청 동해부이의 경우 유의파고의 연별 평균값과 최대값 및 폭풍파 연별 출현횟수가 2009년 이후로 매우 급격하게 증가하는 경향이 나타났으며 해당 자료의 연속성이 확보되지 않은 것으로 확인되었다.
