Abstract：In order to understand the changes of winter temperature in Nanchang City,the linear fitting and harmonic analysis were performed on the data of winter average temperature,maximum temperature,and minimum air temperature in Nanchang city.The results show that the annual average temperature in winter of Nanchang (from December to the February) is 7.1 ℃,and the start time and end time of winter are relatively late from 2010 to 2020.The overall number of winter days shows a slow increasing trend.Through the analysis of the average temperature data for the three months of winter in Nanchang,it was found that there were many extreme weather conditions,large temperature differences in winter,and a phenomenon of "cold this year,hot the next year" occurred.However,the overall average temperature from December to February of the following year tends to gentle.The temperature situation in Nanchang is a microcosm of most southern China,responding to the overall trend of global climate change.With global warming and an increase in extreme weather,people not only need to actively adapt to the changing trend,but also actively respond to the impact of the changing trend.
