초록
1971년부터 2001년까지 해양 및 기상관측 자료를 활용하여 한국 서해에서 기상인자(기온, 바람, 강수량)가 수온과 염분 변화에 미치는 영향을 분석 하였다. 그 결과 수온-기온, 수온-강수량, 염분-풍속은 정상관(+)을, 수온-풍속, 염분-기온, 염분-강수량은 역상관(-)의 관계를 보였다. 기상인자와 해양인자간의 시간지연(time lag)은 표층에서
The effect of meteorological factors such as air temperature (AT), wind speed (WS), precipitation (Pre) on the variation of water temperature (WT) and salinity (Sal) in the West Sea of Korea for the period 1971 to 2001 was illustrated. As a result of this study, WT-AT, WT-Pre, and Sal-WS had positive correlation, reversely WT-WS, Sal-AT and Sal- Pre had negative correlation. In the surface layer, time lag between atmospheric factors and oceanographic factors was 0 to 4 months, on the other hand in the bottom layer, it was delayed 0 to 4 months compared to the surface. WT was affected by AT in the same year, but Sal was affected by precipitation in the previous year. The variation of WT and Sal was in harmony with change of wind speed.
