Hydroclimatic Variability On The Great Plains, Michael J. Keables Feb 1991

Hydroclimatic Variability On The Great Plains, Michael J. Keables

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

This study identifies the spatial variability of the hydroclimatology of the Great Plains. Spatial associations of monthly midtropospheric circulation anomalies, total precipitation, and mean stream discharge are identified using an unrotated principal component analysis. Three hydroclimatic associations, representing synoptic circulation features and associated precipitation and stream discharge patterns, identify specific circulation anomalies and corresponding spatial pattems of surface hydrology in the northern, central, and southern Great Plains. Results indicate that nearly 47% of the hydrologic (precipitation and stream discharge) variability during summer is attributed to synoptic-scale midtropospheric circulation anomalies, with sub-synoptic convectional processes accounting for approximately 42% of the hydrologic …


The Geologic Record Of Wind Erosion, Eolian Deposition, And Aridity On The Southern High Plains, Vance T. Holliday Feb 1991

The Geologic Record Of Wind Erosion, Eolian Deposition, And Aridity On The Southern High Plains, Vance T. Holliday

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Evidence of wind erosion, accumulation of airborne sediments, and drought is preserved on the Southern High Plains. Eolian deposition in the Holocene concentrated between 6000 and 4500 years ago. The Blackwater Draw Formation indicates episodic wind erosion and deposition in the past 1.6 million years. The Ogallala Formation suggests a vast, sandy eolian plain accumulated episodically between 4 and 11 million years. Warmer and drier conditions predicted for the region in a globally-warmer climate will thus be superimposed upon prevailing characteristics of wind and relative aridity that have dominated recent geologic time.
