Abstract The article analyzes the differences in temperature,relative humidity,wind direction,wind speed,and air pressure data between the new and old locations of the Dafang National Basic Meteorological Station in 2018.At the same time,it statistically analyzes the pre - and post station relocation of various meteorological elements from 1991 to 2023 and conducts uniformity tests.The results showed that during the comparative observation period in 2018,the monthly average temperature at the new station was consistently lower than that at the old station.The extreme highest temperature was higher in spring than at the old station,and the extreme lowest temperature was higher in autumn than at the old station.The monthly average air pressure is significantly lower than that of the old station.The monthly average wind speed,monthly maximum wind speed,and monthly maximum wind speed of the new station are significantly higher,and the relative humidity changes are relatively small.After the relocation of the station,the monthly average temperature and monthly average air pressure significantly decreased,and the average highest and lowest temperatures were higher in spring and autumn than in the old station.There was no significant linear change in relative humidity,sunshine,and evaporation.There is non-uniformity in air pressure,average maximum temperature,and wind speed,and using univariate linear regression to correct these factors can significantly improve their uniformity.
