摘要

摘要: 本文使用高分辨率卫星数据研究了2003-2017年南海海表温度及海表温度锋面的变化趋势。研究表明海盆平均的SST增温趋势为0.031℃/年，并且越南东南海域增温最为显著。南海夏季和冬季海盆平均的SST增温趋势基本一致，然而SST增温的空间分布却有明显的季节性差异。夏季吕宋海峡西侧增温幅度最大，高于0.06℃/年。冬季最大的增温则出现在越南东南海域。研究发现大陆沿岸的海表温度锋面强度有增加趋势，这一变化趋势与局地风应力增强有关。南海SST异常和海表温度锋面异常与Niño3.4指数具有较好的相关性，表明南海SST以及海表温度锋面的变化趋势会受到厄尔尼诺过程的影响，具有大尺度特征。

Abstract: The trends of the sea surface temperature (SST) and SST fronts in the South China Sea (SCS) are analyzed during 2003-2017 using high-resolution satellite data. The linear trend of the basin averaged SST is 0.31℃ per decade, with the strongest warming identified in southeastern Vietnam. Although the rate of warming is comparable in summer and winter for the entire basin, the corresponding spatial patterns of the linear trend are substantially different between them. The SST trend to the west of the Luzon Strait is characterized by rapid warming in summer, exceeding approximately 0.6℃ per decade, but the trend is insignificant in winter. The strongest warming trend occurs in the southeast of Vietnam in winter, with much less pronounced warming in summer. A positive trend of SST fronts is identified for the coast of China and is associated with increasing wind stress. The increasing trend of SST fronts is also found in the east of Vietnam. Large-scale circulation, such as El Niño, can influence the trends of the SST and SST fronts. A significant correlation is found between the SST anomaly and Niño3.4 index, and the ENSO signal leads by eight months. The basin averaged SST linear trends increase after the El Niño event (2009-2010), which is, at least, due to the rapid warming rate causing by the enhanced northeasterly wind. Peaks of positive anomalous SST and negatively anomalous SST fronts are found to co-occur with the strong El Niño events.
