Abstract:Based on the observation data of Jingdezhen National Basic Meteorological Station from 1961 to 2023,the climate change characteristics of the average temperature,precipitation,sunshine,rainstorm,high temperature and other high impact weather in Jingdezhen are analyzed by using wavelet analysis and cumulative distance equality method.The results showed that the annual average temperature in Jingdezhen City showed an upward trend of 0.028 ℃/year,and the extreme minimum temperature also showed a significant upward trend,but there was no significant linear change in the average number of high temperature days and high temperature intensity.The average annual precipitation,average annual rainfall days and rainstorm days all show quasi 20-year and quasi 5-year periodic changes,and the periodic change of rainstorm intensity is the most obvious.The main cycle before the 1990s showed quasi 25 year change,the main cycle from the 1990s to the middle of the 2010s shortened,which is quasi 20-year change,and the main cycle after the middle of the 2010s shortened significantly,which is quasi 9-year change.The average annual sunshine hours show a significant downward trend.
