Abstract:Using the daily maximum and minimum temperature data from December 2015 to November 2022 from the Dafang National Basic Meteorological Observation Station and 35 township automatic meteorological observation stations,this study analyzed the characteristics of the changes in the maximum and minimum temperatures in Dafang County and their correlation with regional stations using mathematical statistics methods.The results show that the spatial distribution of the minimum temperature in Dafang County is basically similar throughout the four seasons.The distribution range of high and low values of the maximum temperature varies with the seasons,and there are relatively stable low value centers that are roughly the same in summer and autumn.Altitude is the main influencing factor of the maximum temperature.The accuracy of forecasting decreases as the correlation coefficient decreases,and the error range correspondingly increases.The methods of empirical forecasting and altitude correction forecasting have lower accuracy and more dispersed errors compared to the fitting formula forecasting method.
