【 摘 要 】

Using the observation data from 1960 to 2013 of the prefectural meteorological stations in Western Anhui, this paper analyzes the maximum and minimum temperature changes and regional temperature ranges among the counties with the linear method. The results show that the maximum temperature had a fluctuation within a narrow range; the minimum temperature continuously rose, but the diurnal temperature range decreased. The monthly, seasonal and annual average daily temperature as well as the monthly, seasonal and annual temperature ranges showed a decreasing trend in most areas, and the trend was obvious in winter and summer but weak in spring and autumn. The changes in the maximum and minimum temperatures in Western Anhui are associated with the moisture content in the whole atmospheric layer. The inter-area difference of the changes in the diurnal temperature range decreased from the southwest to the northeast, which is well consistent with the local topography. The author considers that it is the result of the influence of topographic factors.
