Singular value decomposition(SVD)is addopted to investigate the relation of soil temperature anomaly in China to Northern 500hPa height anomaly in the same month of January and January temperature to last December hight,previous and subsequent months,deriving a canonical spatial pattern of pairings for both.Evidence suggests that such patterns are noticeable over Eurasia in the same and previous month.Also,possible physical processes are presented for their interaction on the basis of observational study.
