Zusammenfassung
Analyzing the spatiotemporal characteristics and evolution of meteorological and hydrological droughts can reproduce the process of drought propagation. This study focuses on drought propagation between meteorological and hydrological drought in Yunnan province, Southwest China, using Global Navigation Satellite Systems (GNSS) observations and precipitation data. We identify 7 meteorological and 7 hydrological droughts between January 2011 and May 2021 and find that the meteorological droughts are concentrated in northern Yunnan and last 1-11 months, while hydrological droughts are more severe and larger, lasting 2-16 months. The drought propagation time varies between 2-7 months and is short in the southwest but long in the northeast. We also find that water vapor, precipitation, and water storage have an uneven spatiotemporal distribution with the red river fault (RRF) as the boundary and that the RRF influences the spatial variation of water resources and drought propagation. The results of this study provide valuable insights into the spatiotemporal characteristics and evolution of meteorological and hydrological droughts, which can be used to improve water resources management and mitigate the impact of droughts.
