Dry Spell Trends and Frequencies in the South Central United States

Research dates: 2008-2012
Investigator(s): Michael Roberts, Jill Trepanier, Barry Keim

This research focused on the analysis of 70 weather stations across the South to detect trends in periods lacking rainfall. This also included a study of seasonal variability at these sites to produce return periods.
Through quantifying past periods of dry conditions, this research aimed to support future development of a state-level drought plans in the south central region. With climate model projections pointing towards more frequent - and extended - rain free periods across the South, the development of state-level drought plans is becoming increasingly more important.
