摘要
利用我国188个气象观测站的地理纬度、海拔高度及1971～2000年的气温资料,分析了我国地面观测气温的空间分布规律,得出气温与纬度、海拔、高度的关系。在全国范围内,纬度每增加1°,年平均气温下降0.72℃,7月平均气温下降0.2℃,1月平均气温下降1.33℃;海拔高度每增加100米,年平均气温约下降0.25℃,7月平均气温下降0.31℃,1月平均气温下降0.19℃。
Through doing research on the temperature data from 1971 to 2000 at 188 observation station in China, and the information of the stations, we got the temperature distribution regression in China. It showed that the annual mean temperature and monthly average temperature of July, January decreased 0.72℃, 0.2℃, 1.33° respectively with the latitude increasing one degree. It decreased 0. 25℃, 0. 31℃, 0.19℃ respectively with the station height above sea level increasing one hectometer.
