| Abstract: | The low temperature events were analyzed based on the NCEP/NCAR data and the daily minimum temperature observation data from 135 meteorological stations in the Northwest China during 1961-2009,using the methods of linear regression analysis,Mann-Kendall,running T-test,wavelet analysis,power spectrum and composite analysis.The results show that:(1) The spatial distribution of the extreme minimum temperature in Northwest China presents the distributed tendencies of two high and low interactions.The areas with... |
