Abstract: In order to further improve meteorological services,this paper conducts a statistical analysis of the meteorological data such as temperature,humidity,precipitation,wind speed and other meteorological data from 1959 to 2021 since the establishment of the Wuqing National Meteorological Observatory. The results show that from 1959 to 2021,the annual average temperature,the annual average maximum and minimum temperature all showed an upward trend,the rising trend was relatively obvious in the past 10 years,and the temperature increase was the largest in spring. The annual average relative humidity showed a downward trend,and the decline was the largest in spring. The annual precipitation generally showed a downward trend,and the summer precipitation in the 2000s contributed the most. The annual average wind speed showed a downward trend,and the downward trend was most obvious in winter.
