| 利用50a (1950 - 2007年)的SODA(Simple Ocean Data Assimilation)数据分析了南海上层温度锋分布特征以及季节变化规律。结果表明: 受季风、太阳辐照以及诸多因素影响, 温度锋季节变化明显, 锋面结构复杂。冬季, 温度锋基本沿陆架分布, 存在于南海北部海区, 从台湾海峡一直延伸到北部湾, 发育比较显著; 春季, 主要出现在南海北部海区、北部湾、越南东部海岸, 分布比较广泛;夏季温度锋出现概率增加, 出现区域扩大, 越南东部出现大面积温度锋; 秋季南海中西部海域存在大面积的温度锋。 |

| Abstract: |
| Distribution and seasonal variation of temperature front in the upper layer of the South China Sea are analyzed based on the SODA data from 1958 to 2007. Results indicate that due to the impacts of monsoon, solar radiation, and other factors, temperature fronts varied strongly and seasonally in complicated structures. In winter, a temperature front occurs largely along continental shelf in the northern South China Sea from the Taiwan Strait to the Beibu (Tonkin) Gulf, being quite clear. In spring, it distributes more Widely, mainly in the northern South China Sea, Beibu Gulf, and the eastern coast of Vietnam. In summer, temperature front distributes Widely and occur frequently, especially in the eastern coast of Vietnam. In autumn, temperature front exists in a larger area in the Western and central South China Sea. |
