Potential Regional Impacts Of Global Warming On Precipitation In The Western United States, United States Department Of The Interior, Bureau Of Reclamation

Meterology

Snow and melting of the snowpack provide the principal supply of water to much of the Western United States. Whether global warming threatens this water supply is the focus of this research. This study builds upon a previous Global Climate Change Response Program investigation. Charts were generated of four geopotential height parameters for a domain covering the eastern North Pacific Ocean and western North America. Out of 131 total winter months (from 1946-89), 35 were selected as analogues.

Monthly mean precipitation values for areas in western Montana, northern Utah, and east central Arizona were compared with median values for the …

Precipitation Gauge Testing On The Wasatch Plateau, Utah, During Early 1993, United States Department Of The Interior, Bureau Of Reclamation

Meterology

The Bureau of Reclamation performed an independent evaluation of an ETI (Electronic Techniques, Inc.) precipitation gauge at the High Altitude Site on the western slope of the Wasatch Plateau in central Utah. The ETI gauge could provide a desirable alternative to conventional recording gauges in several applications, including evaluation of cloud seeding projects, if it performs as advertised. The testing program was intended to determine its performance in a winter mountain environment. The ETI precipitation gauge proved to be reliable from time of installation in late November 1992 until removal in late March 1993. The only problem found was an …
