| 摘 要： | 运用中国气象中心提供的中国标准气象站点实测的50年相对湿度月平均数据,采用等值线分析方法,研究了过去50年中国大气相对湿度的动态变化。分析表明：中国相对湿度区域变化,在秦岭淮河一线以北变化范围明显,主要以相对湿度减小为主;秦淮以南相对湿度变化在区域上表现不明显;从季节分析看,夏季变化幅度不大,其它三个季节变化幅度大,特别是冬季变化幅度最大;从区域看,以青藏高原、东北和华北变化显著。

| Abstract: | The dataset from 160 NMO stations with long-term monthly relative humidity data and method of isoline method were used to study the relative humidity variation in China over the past fifty years. The results showed that the humidity generally decreased to the north of Qinling-huaihe River line, with unconspicuous variation to the south of the line. Seasonally, the humidity varies obviously winter, spring and autumn, especially in winter, with an inconspicuous change in summer. Regionally, the humidity has obvious variation in the areas of Tibet Plateau, northeast China and north China. |
