摘  要:
利用来自NOAA的SST(海表温度)资料,计算了近半个世纪以来(1950~2009年)南海—北印度洋SST的整体变化特征,主要计算了整体变化趋势、变化趋势的区域性差异、季节性差异、变化周期。结果表明,近半个世纪以来,南海—北印度洋大部分海域的SST表现出显著的逐年线性递增趋势,其中北印度洋的递增趋势强于南海,印度洋赤道中东部海域的递增趋势尤为明显,可达0.014℃/a以上;南海—北印度洋海域的SST以0.011 5℃/a的速度显著性逐年线性递增,在夏季的递增趋势强于冬季,冬季和夏季分别以0.010 6、0.012 2℃/a的速度显著性逐年线性递增;该海域的SST具有显著的2.4~2.9、3.1~5.7年的显著性变化周期,以及40年以上的长周期震荡。

摘  要:
The long- term trend and periods of sea surface temperature (SST) in the North Indian Ocean and South China Sea were analyzed by using the SST data from NOAA. The general variation trend,regional difference,seasonal difference,variation period were calculated. The results showed that SST in the North Indian Ocean and South China Sea has obvious increasing trend from 1950 to 2009. The increasing trend in the North Indian Ocean is stronger than that in the South China Sea,especially the equator waters in the North Indian Ocean,even up to 0. 014 ℃ / a. SST in the North Indian Ocean and South China Sea has obvious increasing trend totally of about 0. 011 5 ℃ / a. And the increasing trend in summer is stronger than that in winter (0. 012 2,0. 010 6 ℃ / a respectively). SST in the North Indian Ocean and South China Sea has obvious changing trend of 2. 4- 2. 9 years,3. 1- 5. 7 years,and long-term period of above 40 years.
