The Great Plains region of the United States is susceptible to drought of all kinds including meteorological/clima-tological, agricultural, hydrological, and socioeconomic. Drought conditions in the region span varying spatial and temporal scales and the causes include: 1) certain synoptic conditions that favor drought such as mid-tropospheric ridg-ing over the drought-affected area and a weak low-level jet; 2) sea surface temperature anomalies and associated tele-connections; 3) land-atmosphere coupling; and 4) anthropogenic effects. While drought can span as few as a couple of months, the most severe droughts can occur at the decadal scale such as the 1930s Dust Bowl, the worst drought in re-cent history from a societal standpoint. Such droughts in the Great Plains have widespread impacts on agriculture, water resources, human health, and the economy
