Project Description: We are using the methodology outlined in Christian et al. (2019) to develop a global flash drought climatology using evaporative stress anomalies from the NASA MERRA-2 and ERA-Interim reanalysis datasets.  We are also examining specific case studies of flash drought that would be of interest to the stakeholders, including cases that have occurred outside the areas that are considered a flash drought hotspot. Finally, we will be using past case studies to assist with improving understanding of the hydrological and agricultural impacts of flash drought, with an objective of improving projections of future flash drought events.
