Abstract

A review and assessment of the challenges imposed by rapid-onset droughts in the United States is presented. It is recommended that the climate features referred to as 'flash droughts' in the scientific literature be identified based on how rapidly they intensify. These events demonstrate the suddenness with which extreme drought conditions can develop and the high impact that they have on the economy and local ecosystems. Researhers provide an overview of recent research on flash droughts and then present a proposed definition for 'flash drought' and a checklist that can be used to track its development. They discuss the importance of drought monitoring tools and forecasting methods that can quickly capture flash drought onset and predict its evolution over subseasonal time scales.
