## Abstract Drought can be viewed as a threeβdimensional phenomenon rather than simply a surface feature. We characterize drought across the western United States from 1973 to 2002 in a threeβdimensional context by examining its vertical moisture extent using NCEP/NCAR Reanalysis data derived from

β¦ Synopsis
Measurements of the surface energy budget over an Illinois corn field during the summer drought of 1988 yielded Bowen ratio values around 1 compared to potential values of 0.2-0.3 if soil moisture had not been limiting. An analysis of the atmospheric water vapor budget for the upper midwestern United States suggests that the measured decrease in evapotranspiration was significant and may have played a role in the persistence and severity of the drought by reducing the atmospheric water vapor supply and increasing the atmospheric heating rate.

The northern Great Plains of the US is a region that experiences extensive winter snow covers. Meltwater provided by this snow is an important source of freshwater for agriculture, domestic uses and hydroelectric power. The geographic location of the region, however, makes it subject to a variety of
