Abstract：The article uses precipitation and temperature data from 119 meteorological stations in Inner Mongolia,this study explores the characteristics of temperature and humidity changes in Inner Mongolia from 1981 to 2020 using methods such as climate trend rate and standard deviation.Research has found that the temperature in Inner Mongolia decreases from southwest to northeast,and during the study period,the temperature showed a significant upward trend,especially since the 21st century when the summer temperature has increased significantly.The distribution of annual precipitation shows a pattern of more in the east and less in the west,with summer precipitation accounting for 65％ to 75％ of the total annual precipitation.Although there was no significant increase or decrease in the average annual precipitation and summer precipitation in the entire region from 1981 to 2020,there were significant interannual fluctuations and decadal changes.
