Abstract Performed in this paper is rotated EOF analysis of normalized anomaly fields of winter monthly mean temperatures of China and the first six REOFs are taken to represent main spatial patterns,1.e,of South China,NE China,western NW China,eastern Tibetan Plateau,SW China and North China,Analvsis of their time coefficients for the related temporal evolutionsshows that 1) a remarkable warming trend occurs in other regions than the Tibetan Plateau and South China, 2) opposite signs of anomaly are dominant in the early and late winter’ and 3) the NW China pattern are in phase behind the Plateau pattern but ahead of the others when they arein the same period.
