Modeling the impact of iIrrigation on precipitation over the Great Plains.
… the rapid expansion of irrigation throughout the Great Plains has threatened the sustainability of the Ogallala Aquifer. Irrigation has been shown to modify the surface energy and water budgets over the Great Plains by altering the partitioning of latent and sensible heating. An increase in latent …

RECONSTRUCTING CLIMATE ON THE GREAT PLAINS FROM BURIED SOILS: A QUANTITATIVE APPROACH
The Great Plains, U.S.A. lack quantitative paleoclimatic data for the late Quaternary largely because two common sources of paleoclimatic data, tree ring and pollen records, are rare in the region. Sequences of buried soils, however, are commonly preserved in eolian and alluvial sediments on the …

Eastern Redcedar Encroachment In Southern Great Plains Grasslands: Wildlife Consequences And Management Implications
Anthropogenic change in the Great Plains of North America within the past two centuries has facilitated extensive woody encroachment by eastern redcedar (Juniperus virginiana, hereafter redcedar). Conversion of grassland to redcedar woodland occurs rapidly as a result of the interaction between …

Competition and Phenology of Invasive and Native Grasses in the Northern Great Plains
Invasive species cause substantial ecological, social, and economic impacts. In South Dakota, Bromus inermis (smooth brome) and Poa pratensis (Kentucky bluegrass) are substantial threats to remnant prairies by forming monotypic stands that are resistant to restoration while decreasing diversity and …

The Impacts of Wind Farms on Cumulus Development in the Central Great Plains
Cumulus clouds have a net cooling effect on the surface radiative balance by reflecting more downwelling solar radiation than absorbing upwelling terrestrial radiation. As boundary layer cumuli form from buoyant, moist plumes ascending from the surface, their growth may be hindered by the turbulent …
