Abstract: The 43-year average temperature data (from 1964 to 2006) from 138 stations in Northwest Westerly Region and from 375 stations in eastern Monsoon Region were used to compare their spatiotemporal characteristics. The change trends of temperature in both regions were basically same, generally increasing except for small fluctuations. The inter-annual change extent was larger in the Westerly Region than in the Monsoon Region. Apart from one station in the Westerly Region and four stations in the Monsoon Region, the other regions had positive temperature change rate. The locations in the Westerly Region with rate ≥0.4°C/10a are in northwestern Xinjiang, eastern Xinjiang to western Qinghai and middle of Inner Mongolia, and that in the Monsoon Region are in the relatively weak monsoon-affected areas, mainly in northern China and northeastern China.

Key words: northwest Westerly Region, eastern Monsoon Region, inter-annual change, temperature tendency, comparative analysis
