RISEvidence that Recent Warming is Reducing Upper Colorado River Flows
Publisher: American Meteorological Society
Abstract: AbstractThe upper Colorado River basin (UCRB) is one of the primary sources of water for the western United States, and increasing temperatures likely will elevate the risk of reduced water supply in the basin. Although ...
Assessing the Risk of Persistent Drought Using Climate Model Simulations and Paleoclimate Data
Publisher: American Meteorological Society
Abstract: rojected changes in global rainfall patterns will likely alter water supplies and ecosystems in semiarid regions during the coming century. Instrumental and paleoclimate data indicate that natural hydroclimate fluctuations ...
Long-Duration Drought Variability and Impacts on Ecosystem Services: A Case Study from Glacier National Park, Montana
Publisher: American Meteorological Society
Abstract: Instrumental climate records suggest that summer precipitation and winter snowpack in Glacier National Park (Glacier NP), Montana, vary significantly over decadal to multidecadal time scales. Because instrumental records ...
Variability Common to First Leaf Dates and Snowpack in the Western Conterminous United States
Publisher: American Meteorological Society
Abstract: ingular value decomposition is used to identify the common variability in first leaf dates (FLDs) and 1 April snow water equivalent (SWE) for the western United States during the period 1900?2012. Results indicate two modes ...
Northern Hemisphere Modes of Variability and the Timing of Spring in Western North America
Publisher: American Meteorological Society
Abstract: patial and temporal patterns of variability in spring onset are identified across western North America using a spring index (SI) model based on weather station minimum and maximum temperatures (Tmin and Tmax, respectively). ...
Hydroclimatology of the Missouri River Basin
Publisher: American Meteorological Society
Abstract: AbstractDespite the importance of the Missouri River for navigation, recreation, habitat, hydroelectric power, and agriculture, relatively little is known about the basic hydroclimatology of the Missouri River basin (MRB). ...
The Continuum of Hydroclimate Variability in Western North America during the Last Millennium
Publisher: American Meteorological Society
Abstract: he distribution of climatic variance across the frequency spectrum has substantial importance for anticipating how climate will evolve in the future. Here power spectra and power laws (?) are estimated from instrumental, ...
Basinwide Hydroclimatic Drought in the Colorado River Basin
Publisher: American Meteorological Society
Abstract: The Colorado River basin (CRB) supplies water to approximately 40 million people and is essential to hydropower generation, agriculture, and industry. In this study, a monthly water balance model is used to compute ...
Climatic Controls on the Snowmelt Hydrology of the Northern Rocky Mountains
Publisher: American Meteorological Society
Abstract: The northern Rocky Mountains (NRMs) are a critical headwaters region with the majority of water resources originating from mountain snowpack. Observations showing declines in western U.S. snowpack have implications for ...
