【摘要】 对1971～2022年内蒙古地区西部、中部及东部地区二十四节气气温、降水、相对湿度和日照的变化特征进行了统计分析，得出：1）三区域气温、降水呈现出明显的年循环特征。三区域平均气温的最大值和最小值均分别出现在小暑和小寒节气，春分、清明和立冬节气气温波动最大；中、西部地区在大暑节气降水量最多，东部在小暑节气最多；中、东部在大暑节气相对湿度达到最大，西部在立秋达到最大；三区域均在小满节气日照时数最长。2)1971～2022年，三区域平均气温呈增加趋势，相对湿度和日照时间呈现出减少的趋势。更多还原

【Abstract】 A statistical analysis of temperature, precipitation, relative humidity, and sunshine hours across the 24 solar terms in the western, central, and eastern regions of Inner Mongolia from 1971 to 2022 was conducted. The key findings include: 1) The temperature and precipitation values in the three regions exhibit distinct annual cyclical patterns. The highest and lowest average temperatures for the three regions were recorded during the Minor Heat and Minor Cold,respectively. Significant temperature fluctuations were observed around the Spring Equinox, Pure Brightness, and Beginning of Winter. The highest precipitation levels were recorded during the Major Heat in the central and western regions, whereas the eastern region experienced the highest precipitation during the Minor Heat. Relative humidity reached its peak during the Major Heat in the central and eastern regions, whereas in the western region, it peaked during the Beginning of Autumn. All three regions reached their peak sunshine hours during the Grain Buds. 2) The average temperature in all three regions showed an increasing trend from 1971 to 2022, whereas relative humidity and sunshine hours exhibited a decreasing trend.更多还原
