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.

The decadal features of winter air temperature in northeast China and winter AO index and their relationship are investigated by using the monthly air temperature data at 160 stations in China,the AO index and the NCEP\NCAR reanalysis data.

This paper summarizes the research progress of winter air temperature variations of three provinces(i.

Spatial anomaly features and time evolution rule of the winter mean air temperature in China\'s east monsoon area are analyzed using data from 375 stations over the years of 1961—2006,adopting the methods of linear regression analysis,multinomial fitting,EOF,REOF,Mann-Kendall,Glide t-examination,Wavelet analysis and power spectrum analysis etc.

Then the ensemble canonical correlation prediction(ECC) method is used to predict winter temperature over China.

This study reconstructed the series of mean winter temperature and set up the equation of bi-determiner about the snowing in winter and the precipitation during dry seasons with historical documents during 1721-1900, at the same time reconstructed the decade series of mean winter temperature with other materials during 1856-1900.
