초록

본 연구에서는 1995년부터 2016년까지 여름철(5월~8월) 내 동해 연안역에서 발생하는 용승에 대한 지수(Upwelling age, UA)를 산출하고 수온(Surface sea temperature, SST)과의 상관성을 분석하였다. 동해 연안 근처의 6개 기상청 자동기상관측장비 Automatic weather system, AWS)와 종관기상관측장비(Automated synoptic observing system, ASOS) 지점에서 관측된 바람자료를 이용하여 용승지수를 계산하였으며, 수온은 국립수산과학원에서 제공하는 연안정지 자료(Coastal oceanographic data, COD)와 실시간 수온 관측 시스템 (Real-time information system for aquaculture environment, RISA) 자료를 이용하였다. 정량적으로 UA의 값은 낮게 산출되었지만 냉수대 발생 시기에 UA가 상승하였으며 실제와 유사하게 모사해 내었다. UA-SST와의 상관분석에서 음(-)의 상관이 우세하게 나타났다. 냉수대가 극심했던 2013년 6월~8월 UA-SST 상관분석 결과, 6개 분석지점에서 -0.65~-0.89의 매우 높은 상관성을 보였으며 이는 UA가 강할수록 SST가 하강하여 강한 냉수대가 출현하였음을 증명하였다. 본 연구를 통해 동해연안역의 냉수대에 따른 용승발생 경향을 장기적으로 평가 할 수 있었으며, 용승의 크기와 강도에 따른 연안 양식어장의 피해를 최소화 하는데 기여할 것으로 사료된다.

In this study, we examined the UA (upwelling age) using wind data of AWS/ASOS in the East Sea coast and the correlation between UA and SST (sea surface temperature) from May to August in 1995 to 2016. The data used the 6 observations of the wind data of AWS/ASOS and the SST data of the COD/RISA provided by the National Institute and Fisheries Science near the East Sea coast. The UA was calculated quantitatively low but it rose when the actual cold water mass occurred. Correlation analysis between UA and SST showed the negative (-) r (correlation coefficient) predominately. At the time of cold-water mass in June to August 2013, the r had a very high negative value of -0.65 to -0.89 in the 6 observations. It proved that as the UA increases, the SST is lower. By knowing the UA, we were able to evaluate the trend of upwelling in the cold-water mass of the East Sea coast in the long term and it will contribute to minimizing the damage to aquatic organisms according to the size and intensity of the upwelling.
