To understand the climate change in Dianzhong region,Yunnan Province,the near-surface observations from 1963 to 2013 in four cities(i.e.Kunming,Chuxiong,Yuxi,and Qujing) were analyzed.Significant warming trend was found in the past 51 years in all the four cites.Comparing the warming trend in different seasons,it was found that the warming rate was fastest in winter.The warming phenomenon was most significant in Kunming,which might be relevant to the urbanization there in the past decades.The annual precipitation presented a slightly decreasing trend.The precipitation increased in the dry seasons(spring and winter),while decreased in the wet seasons(summer and autumn).In the four cities,the decrease of precipitation was most significant in Kunming,while it was slight in Chuxiong.In addition,the decrease of relative humidity was found,and the different between the seasons is not huge.The correlations between different meteorological variables can also be found through the wavelet analysis.It was found that the 36-year cycle of temperature was relevant to that of relative humidity,and the 16-32 years cycle of relative humidity was also related to that of precipitation in Dianzhong region.
