| Abstract: | Based on the monthly air temperature and precipitation data from 160 observational stations in China from 1951 to 2009,the surface humid index was calculated and its relationships with air temperature and precipitation were analyzed.The inter-decadal characters of the surface humid index were discussed and the geographical distributions of the annual surface humid index were presented.The results indicate that drought is the main characters in the east of northwestern China,north China,northeast China,the m... |
