Altitude Effect of Relative Humidity and Impacts of Global Warming on It

Global climate change has a wide range of impacts on global environment. This paper presented an investigation on the altitude effects of relative humidity and the impacts of global warming on the relationship between altitude and the pattern of relative humidity using the meteorological 50-year data of 37 stations with an altitude of 1800-3200m in China. The investigation indicated that there was a very distinct altitude effect of relative humidity between the altitude range of 1800m-3200m, with a negative correlation between the altitude and relative humidity. In addition, the warming increased the altitude effect of relative humidity in winter while decreased that in summer.
