Description :
Temperature and precipitation time series datasets from 1961 to 2005 at 65 meteorological stations were used to reveal the spatial and temporal trends of climate change in Xinjiang, China. Annual and seasonal mean air temperature and total precipitation were analyzed using Mann-Kendall (MK) test, inverse distance weighted (IDW) interpolation, and R/S methods. The results indicate that both temperature and precipitation increased in the past 45 years, but the increase in temperature is more obvious than that of precipitation. This increase is different inside Xinjiang, in winter or in summer. Hurst index (H) analysis indicates that climate change will continue the current trends.
