Seasonal Variations In The Diurnal Characteristics Of Heavy Hourly Precipitation Across The United States, Julie A. Winkler, Brent Robert Skeeter, Paul Yamamoto

School of Natural Resources: Faculty Publications

Hourly precipitation data from 1967 to 1983 for the conterminous United States were harmonically analyzed in order to document the diurnal variability of several categories of heavy precipitation during winter, spring, summer, and autumn. The analysis revealed that the diurnal characteristics of hourly precipitation vary considerably with season, geographic region, and precipitation intensity. During winter and spring, a weak, later-morning frequency maximum prevails for the lightest (2.5-6.2 mm h-1) precipitation category. As intensity increases (to 6.3-12.6, 12.7-25.3 and >25.4 mm h-1), the amplitude of the diurnal cycle also increases, and a nocturnal maximum becomes apparent across much of the eastern …

A Preliminary Study Of The Hydrogeology Of The Dakota Formation In Douglas, Sarpy And Washington Counties, Eastern Nebraska, Thomas Mark O'Connor

School of Natural Resources: Dissertations, Theses, and Student Research

This study provides preliminary information on the hydrogeology of the Dakota Formation within a 1,000 square-mile area in eastern Nebraska. Isopach maps of the Dakota Formation and individual sand and gravel beds were constructed using a computer contouring program. Hydraulic conductivity values for water-bearing sand beds in the Dakota were estimated using the equation for calculating the specific capacity of wells and results from a grain-size analysis. Concentrations of major dissolved species were determined for samples collected from twenty five wells. The Dakota Formation is characterized by an increase in thickkness and an increase in percentage of clay versus sand …

Use Of Climatic Data To Identify Potential Sites In The United States For Growing Papaver Bracteatum As A Pharmaceutical Crop, R.E. Neild

School of Natural Resources: Faculty Publications

A procedure utilizing maps in the National Climatic Atlas was used to survey the United States to find areas for domesticating Papaver bracteatum, a wild poppy from the Trans-Causasus. This poppy had unique properties which make it a possible heroinless source of codeine. Climatic conditions similar to the native habitat and requirements of Papaver bracteatum can be found in areas of western Utah, northern Nevada, southern Idaho, eastern Washington and Oregon, northeastern California and southwestern Wyoming. A detailed climatic analysis was made to evaluate more specific locations within this large area. A site near Medford, Oregon was selected as best …

Competition For Food And Space In A Heteromyid Community In The Great Basin Desert, Cliff A. Lemen, Patricia W. Freeman

School of Natural Resources: Faculty Publications

ABSTRACT.—A series of removal experiments were performed on Dipodomys merriami, D. microps, and Perognathus longimembris to test for the importance of competition for food and microhabitats in a heteromyid community in the Great Basin Desert. Each of these species was removed singly to determine the short-term effects on the microhabitat preferences of the remaining species. We correctly predicted, based on differences in diet, that the removal of D. microps (a foliovore) would have no effect on D. merriami or P. longimembris (granivores). Using the dominance hierarchy theory, we correctly predicted that removal of a larger heteromyid, D. merriami …

A Climatology Of Mean Monthly Snowfall For The Conterminous United States: Temporal And Spatial Patterns, John A. Harrington Jr., Randall S. Cerveny, Kenneth F. Dewey

School of Natural Resources: Faculty Publications

Mean monthly snowfall data for 216 stations across the conterminous United States were analyzed to produce a climatology that identifies statistical, spatial and intraseasonal aspects. Geographic variations in the length of the snowfall season are characterized using two statistics: the number of months of snow and the Snow Concentration Index (SCI).

The Annual distribution of mean monthly snowfall is also examined using harmonic analysis. Snowfall across the conterminous United States generally peaks in February; earlier snowfall maxima are found in the Great Lakes area and in the Pacific Northwest, whereas late February or March maxima occur in the western High …

Satellite-Derived Maps Of Snow Cover Frequency For The Northern Hemisphere, Kenneth F. Dewey

School of Natural Resources: Faculty Publications

A satellite imagery-based Northern Hemisphere snow cover data archive was mapped for the period 1966-84: The maps were digitized in order to create the first hemispheric, spatially data-continuous climatologies of snow cover. Annual and monthly climatologies were created and compared to several standard or frequently referenced climatologies. Results of this analysis indicate that the satellite-based climatology provides a much more detailed climatology for the higher latitude and highland regions of the Northern Hemisphere. The satellite imagery-based maps, when compared to the historical snow cover climatologies, indicated more extensive high-latitude snow cover concurrent with a northward shift in the southern extent …

A Preliminary Investigation Of A Relationship Between South American Snow Cover And The Southern Oscillation, Randall S. Cerveny, Brent R. Skeeter, Kenneth F. Dewey

School of Natural Resources: Faculty Publications

A ten-year (1974-83) satellite record of snow cover is compared to a standard index of the Southern Oscillation. South American snow cover area during the May-October snow season is found to be correlated significantly with the winter SOI values of the same year. The relationship is inverse; periods of low SOI values are associated with extensive South American snow cover while periods of high SOI values occur during years of diminished snow cover. The movements of the Pacific anticyclone and the midlatitude westerlies and subsequent changes in precipitation and temperature patterns are discussed in an analysis of this relationship.

Interference Competition In A Heteromyid Community In The Great Basin Of Nevada, Usa, Cliff A. Lemen, Patricia W. Freeman

School of Natural Resources: Faculty Publications

Removal experiments with three species of heteromyid rodents were performed during two summers in the Great Basin of Nevada, USA. These experiments were designed to determine the importance of interference competition in these species by quantifying the short-term responses to the removal of one or more of the species. Our results indicate that the removal of a large species (Dipodomys merriami) does have a positive effect on a smaller species with a similar diet (Perognathus longimembris). These results and others presented are consistent with a hypothesis of interference competition. However, while there is short-term increase in …
