Recently,many studies have described the relationship between winter temperature in China and some climate systems including the Siberian high(SH),the Arctic Oscillation(AO),ENSO and the western Pacific teleconnection pattern(WP).

warmer,normal and colder categories)is proposed based on the winter temperature data observed at 565 stations in China during 1956-2005,where the IWWI is defined as the ratio of the station number of warmer category over the total number of stations.

By using the data set of the mean monthly global sea surface temperature during the period of 1951~ 1997, mean monthly global wind fields, the surface air temperature of 100 stations in eastern China during the same period, the spatial and temporal features and its variations for winter temperature anomalies in eastern China are analyzed.

We find a good correlationship between annual winter mean temperature (T) and snowfall-days (D) in the Hefei area at the measurmental period, and the regr.

Based on the monthly temperature at 160 stations of China and the NCEP/NCAR reanalysis data from 1951 to 2005,the variation of spatial mode for winter temperature in China and its relationship with the atmospheric circulation were studied.

Based on monthly mean temperature data of 160 stations in mainland China during the period 1951—2000,the Empirical Orthogonal Function(EOF),wavelet analysis and composite analysis are used to analyze the spatial distribution and temporal evolution characteristics of the winter temperature in China.
