Heat and Momentum Budgets in the Coastal Seas under the Influence of East Korea Warm Current = 東韓暖流 影響下의 沿岸海域에서 熱과 運動量 收支

국문 초록 (Abstract)

東韓暖流의 通路에 있는 4個 束草, 江陵, 蔚山, 忠武 沿岸海에서 10年동안 觀測된 氣象 및 海洋 資料를 熱과 運動量 收支의 月變化를 調査하기 위해 分析되었다. 현열은 4個 沿岸海域에서 蔚山 沿岸海에서 8月을 제외하고 4月에서 8月까지 陰의 값을 갖고 6月에 最小値를 갖이며, 이것은 大氣와 海洋境界層을 通한 熱傳度에 依해 海洋이 熱을 얻게 된다. 反面에 10月부터 2月까지 陽의 값을 갖이며 海洋으로부터 熱의 損失을 뜻한다. 잠열의 月別變化는 현열과 유사한 경향을 갖이며, 잠열이 4月부터 8月까지 減少하고 10月부터 2月까지는 增加한다. 즉 잠열의 轉移가 겨울에 增加하고 여름에 減少한다. 4個 沿岸海에서 月平均 風速은 겨울에 强하며 그외 季節에는 比較的 弱하다. 月平均 運動量 플럭스의 變化는 6月에서 8月까지 작은값을 나타내며, 12月부터 2月까지는 큰값을 나타낸다. 運動量 轉移는 硏究海域의 大氣과 海水의 冷却을 유도하는데 있어 熱플럭스와 協力하는 것 같다.

Ten years' meteorological and oceanographical data observed in the four coastal seas-Sokcho, Kangnung, Ulsan and Chungmu in the path of the East Korea Warm Current were analyzed for investigating the monthly variations of heat and momentum budgets. The sensible heat fluxes from April to August had negative values with a minimum in June except for August in the Ulsan coastal sea, which showed the heat gain to the sea resulting from heat conduction across the air-sea interface. On the other hand, from October to February had positive values, which mean the heat loss from the sea. Monthly variations of latent heat fluxes showed similary tendencies of monthly variations of sensible heat fluxes and the heats decreased from April to August, but increased from October to February. That is, the latent heat transfer from sea into atmosphere increases in winter, but decreases in summer. Mean wind speeds in the four coastal seas were strong in the winter season, but they are relatively weak in the other seasons. The distributions of monthly averaged momentum fluxes showed small magnidutes from June to August, but large magnitudes from December to February. The momentum transfer in the coastal seas seemed to be coupled with heat fluxes on inducing the cooling of air over the sea surface or water at the sea surface in the study area.
