| 摘要: |
| 利用韩国海洋数据中心(Korea Oceanographic Data Center)发布的水文数据分析了黄海暖流源区附近温盐结构及其季节变化,结果表明：年平均状态下对马暖流在济州岛东南存在向西向入侵的趋势,其入侵存在明显的季节变化：秋季最强,冬、春季开始减弱,夏季最弱。济州岛西侧,约在33°30′N、125°30′E处存在一支伸向西北的高盐舌,该高盐舌盐度同样具有明显的季节变化：冬季最强,春季开始减弱,夏季降至最低,秋季盐度开始缓慢回升。黄海区盐度的变化要滞后于对马暖流区盐度变化。冬季朝鲜沿岸水南下入侵程度最强,能到达34°N以南的位置。 |

| Abstract: |
| Historical hydrological data released by KODC (Korea Oceanographic Data Center) were used to analyze the thermohaline structure and its seasonal change near the Yellow Sea Warm Current source region, the results showed that: In the southeast of the Cheju Island, the westward invasion trend of the Tsushima Warm Current Water near the bottom layer, has an obvious seasonal changes: peaks in autumn, began to weaken in winter and spring, and weakest in summer. West of Cheju Island(33 ° 30"N, 125 ° 30"E), there’s a Salty tongue towards the northwest all year round, its salinity also has a lagging seasonal variation: peaks in winter, began to weaken in spring, the weakest in summer, and autumn began to rise. The southward intrusion of the North Korea Costal Water peaks in winter, which can reach to the south of 34 ° N. |
