Flash Drought Identification: Climatological Analysis and Case Studies

Flash droughts are characterized by their rapid development toward drought conditions. Rapid drought onset occurs when a combination of extreme atmospheric anomalies (such as lack of rainfall, higher surface temperatures, higher surface wind speeds, and higher vapor pressure deficient) persist for several weeks. Due to a rapid depletion in soil moisture and increased evaporative stress associated with these events, flash droughts can lead to significant agricultural yield loss, place excessive stress on ecosystems, and increase the risk of wildfires.

An impact-based flash drought identification methodology for gridded datasets using the standardized evaporative stress ratio (SESR) is presented. Additionally, an overview is provided on the development of the methodology and various applications of flash drought identification. Key topics include flash drought hot spots across the U.S., regional characteristics of flash droughts across U.S. climate regions, the temporal and spatial evolution of the 2012 flash drought, and flash drought as a precursor to the 2010 Russian heatwave event.

Brief Bio:

Jordan Christian received his B.S. Degree in Meteorology from the University of Oklahoma, his M.S. Degree in Atmospheric Science from the University of Wyoming, and is currently a Ph.D. student in Meteorology at the University of Oklahoma. His research interests include drought to pluvial dynamics, land-atmosphere interactions, and are currently focused on flash drought development from local to global scales.
