droughtflash droughtstreamflowbaseflowStreamflow flash droughts (SFDs), characterized by a rapid decline in streamflow over a relatively short period, affect water availability, hydropower generation, and the ecosystem. However, atmospheric and land processes that drive SFDs in the monsoonal climate of ...
Flash droughts are a recently recognized type of extreme event distinguished by sudden onset and rapid intensification of drought conditions with severe impacts. They unfold on subseasonal-to-seasonal timescales (weeks to months), presenting a new challenge for the surge of interest in improving subsea...
Hydrological drought: Subsequently groundwater recharge and streamflow will be reduced and a hydrological drought may develop. A reduced recharge leads to lower groundwater heads and storage Linkage: Ordered in stages of drought severity Why was defining what constitutes a famine highly political in the...
Atmospheric conditions [geopotential height at 500hPa, mean sea level pressure, wind at 850 hPa, and integrated water vapour (IWV)] were analyzed for the flash drought of 1979 (Supplementary Fig.3). Atmospheric anomalies for one pentad before the onset, during peak intensity, and one pentad af...
Specific hydrological events were attributed to changes observed in this paper, e.g., the hydrological drought in 2010–2012. Based on the random forest analysis, mean rainfall did demonstrate some importance in increasing flashiness in the north and west (“Dec. Peak region”), and indeed the...

Tree growth is influenced by climate conditions, patterns in tree rings and isotopic composition of materin within each ring reflect variations in past climate, can see drought and streamflow Ocean sediment Look at minerals trapped from dead plankton and stuff ...
Flash floods are largely driven by high rainfall rates in convective storms that are projected to increase in frequency and intensity in a warmer climate in the future. However, quantifying the changes in future flood flashiness is challenging due to the
Flash droughts, characterized by a rapid onset and severe intensity, pose a serious threat to water resource management. Extensive research has indicated that drought has lagged impacts on streamflow. Nevertheless, the hydrometeorological conditions by which streamflow dynamics respond to drought within ...
The US drought monitor gives a broad overview of physical conditions in an area and is based on a variety of factors such as “precipitations, streamflow, reservoir levels, temperature and evaporative demand, soil moisture, and vegetative health” [21]. Stage height and discharge are more ...
