The United States experienced a severe drought which peaked in 2012 and which was characterized by near-record extent, record warmth, and record dryness in several areas. For some regions, the 2012 drought was a continuation of drought which began in earlier years and which continued through 2014.


The 1998-2014 drought episode is compared to the two other major drought episodes of the 20th century in terms of duration, areal extent, intensity, and spatial pattern using operational datasets produced by the NOAA National Centers for Environmental Information. It is characterized by more short-term dryness, more concurrent (regional) wetness, and warmer temperatures than the other two drought episodes. The implications of these differences for water resource managers and decision-makers are discussed.
