基于欧洲中尺度气象预报中心（ ECMWF）提供的ERA?Interim地表温度，利用经验正交函数（ EOF）等方法，分析了青藏高原四季地表温度的时空变化特征。结果发现：青藏高原春、夏、冬季地表温度变化以整体型为主，并且大部地区地表温度呈现升高的趋势；秋季地表温度略有下降趋势，并且以东部和西部地表温度的反向型异常变化最为显著。此外还发现，青藏高原不同季节地表温度的异常变化具有一定的联系，其中整体型变化可以持续3个季节。

The ERA?Interim surface temperature data from European Centre for Medium?Range Weather Forecasts ( ECMWF) are used to analyze the spatial and temporal variation of the seasonal surface temperature over the Tibet?an Plateau using Empirical Orthogonal Function(EOF).The results show that in spring,summer and winter,the sur?face temperature tends to increase in the whole Plateau without obvious spatial variation;while in autumn,surface temperature tends to decrease slightly in most area,and a significant opposite variation trend exists between the east?ern and western area of the Plateau. In addition,there are some definite relations between the surface temperature anomaly variations in different seasons,and the integral type can last for 3 seasons.
