Severe droughts have frequently occurred in Yunnan Province in recent years, and it has become a focus of public concern whether the droughts have got in normalization. In this paper, we analyzed the droughts in the aspects of hydrology, drought history, hydrologic factors, and drought prediction. Supported by historical meteorological and hydrological records, we investigated the possibility whether global warming has increased drought frequency in some regions in the last one hundred years. The results provide strong evidence that droughts in Yunnan Province have become normalization. However, the normalization of droughts only occurred in the recent decade. As for the drought trend in Yunnan in the future, it is still difficult to predict by relying on current technology and research findings.
