THE VARIATION COEFFICIENT OF WATER TEMPERATURE AND SALINITY IN THE SOUTHERN SEA OF KOREA

韓國 南海의 水溫과 분의 變動係數

The study on the variation coefficient of water temperature and salinity was comducted during the year from 1968 to 1980 in the Southern Sea of Korea. The results obtaland from the study as followes; 1. The variation coefficient of water temperature and salinity wewe large either at the front area or the thermocline and malocline area. 2. The variation coefficient of water temperature was the largest at the time when the power was strong ty each water mass(The largest value in Tsushima and Yellow Sea Warm Current area was occurred at the 50m layer in the Summer, and that in the South Korean Coastal Water area and the Southern Part of Yellow Sea was at all layer in the Winter). 3. The variation coefficient of salinity was the largest at the surface layer in warm current area that was influenced by the low salinity of the East China Coastal Water in the Summer ,and that of salinity in the South Korean Coastal Water area and Soutern Part of Yellow Sea was nearly half of the value of the warm current area.

1968-1980年의 韓.日共同海洋調査點中 韓國側 63個定點의 海洋調査資料를 使用하여 月別 水溫 및 분의 變動係數를 分析 硏究한 缺課의 要約은 다음과 같다. 變動係數는 水溫과 분의 前線域이나 혹은 躍層形成海域에서 크게 나타났다. 水溫의 變動係數는 각 水塊의 勞力이 가장 强한 時期에 最大値를 나타냈다(對馬 暖流와 黃海暖流域의 夏季 中層에서, 南海岸沿岸水 및 西海南部域의 冬季의 全層 에서 最大). 鹽分의 變動係數는 東支那海 低鹽水의 影響을 많이 받는 夏季에 暖流系水의 表層水에서 크게 나타나며, 沿岸水 및 西海南部域에서는 暖流系水値의 1/2정도였다.
