摘　　要：利用MODIS反演的海表温度数据以及东黄海区表面温度历史数据等,对2014年在25°~40°N、120°~128°E范围内的东海及黄海部分海域表层水温状况进行了分析和研究。结果表明:1、2014年东黄海表层水温的最大值约为35℃,于8月出现在台湾西南沿岸,表层水温的最小值于1月出现在黄海北部为-2^-1℃;2、2014年东黄海表层水温上半年长江口以北海域(包含长江口)的表层水温偏高,长江口以南海域的海表温度偏低,7~9月(夏季)长江口以南海域水温偏高,长江口以北海域略有偏低,10~12月大部分海域水温偏低;3、海表温度梯度与常年相比变化不大,仅在冬季时,黄海暖流的暖水舌前锋较常年的平均状态略有偏北;4、研究海域在5~6月增温最快,温度上升迅速,是引发赤潮的重要原因之一。Sea surface temperature（SST） of East the Yellow Sea（EYS） in 2014 retrieved from MODIS and history data were used to analyze the distribution of SST in the region of 25° -40°N, 120° - 128°E. The results showed that： a） The maximum SST of EYS in 2014 was about 35 ℃, and it appeared in the southwest coast of Taiwan in August. The minimum SST of EYS in 2014 was - 2 - - 1 ℃, and it appeared in north Yellow Sea in January. b） SST was higher than normal year in the north of EYS （ demarcated by the Yangtze river estuary, the Yangtze river estuary area included） while it was lower in the south of EYS （ demarcated by the Yangtze river estuary, the Yangtze river estuary area not included ） in the first half of 2014. SST was higher than normal year in the south of EYS in summer （July to September） while it was lower in the north of EYS. SST was lower than normal year in most of the research area from October to December. c） SST gradient approached to normal yeaer, with the exception that the warm water tongue of the Yellow Sea warm current moved slightly northwards during the winter, d） SST rose rapidly in the research area in May and June, and it might be one of the major reasons for the outbreak of algal blooms.
