Based on the data observed from the meteorological stations in Northwest China for the periods from the year of beginning observation to the year of 2000 and NCEP/NCAR reanalysis monthly mean data, the characteristics of the present climate change in Northwest China have been comprehensively analyzed. The study reveals the observed evidence of the climate transition from the warm dry pattern to the warm wet pattern. And the tendency of the climate change for the future multi-decades have also been estimated in this paper.
