Based on the daily data of temperature and precipitation of 108 meteorological stations in Southwest China from 1960 to 2009, the AA. calculate the monthly and yearly surface humid indexes, as well as the extreme drought frequency. According to the data, the temporal and spatial characteristics of the extreme drought frequency in inter-annual, inter-decadal, summer monsoon period and winter monsoon period are analyzed. In general, it is shown that the southwestern Sichuan Basin, southern Hengduan Mountains, southern coast of Guangxi and northern Guizhou are the areas where the extreme drought frequency has significantly increased in the past 50 years. The 1990s is the wettest decade. In the 2000s, the extreme drought frequency rises quickly, but the regional differences reduce
