RISSeasonal and Spatial Patterns in Diurnal Cycles in Streamflow in the Western United States
Publisher: American Meteorological Society
Abstract: The diurnal cycle in streamflow constitutes a significant part of the variability in many rivers in the western United States and can be used to understand some of the dominant processes affecting the water balance of a ...
Onset of Snowmelt and Streamflow in 2004 in the Western United States: How Shading May Affect Spring Streamflow Timing in a Warmer World
Publisher: American Meteorological Society
Abstract: Historic streamflow records show that the onset of snowfed streamflow in the western United States has shifted earlier over the past 50 yr, and March 2004 was one of the earliest onsets on record. Record high temperatures ...
Untitled
Publisher: American Meteorological Society
Abstract: AbstractEstimates of precipitation from the Weather Research and Forecasting (WRF) Model and the Parameter-Elevation Regressions on Independent Slopes Model (PRISM) are widely used in complex terrain to obtain spatially ...
How Does Availability of Meteorological Forcing Data Impact Physically Based Snowpack Simulations?
Publisher: American Meteorological Society
Abstract: hysically based models facilitate understanding of seasonal snow processes but require meteorological forcing data beyond air temperature and precipitation (e.g., wind, humidity, shortwave radiation, and longwave radiation) ...
Spring Onset in the Sierra Nevada: When Is Snowmelt Independent of Elevation?
Publisher: American Meteorological Society
Abstract: Short-term climate and weather systems can have a strong influence on mountain snowmelt, sometimes overwhelming the effects of elevation and aspect. Although most years exhibit a spring onset that starts first at lowest ...
A Comparison of Methods for Filling Gaps in Hourly Near-Surface Air Temperature Data
Publisher: American Meteorological Society
Abstract: ear-surface air temperature observations often have periods of missing data, and many applications using these datasets require filling in all missing periods. Multiple methods are available to fill missing data, but the ...
Relationships between Barrier Jet Heights, Orographic Precipitation Gradients, and Streamflow in the Northern Sierra Nevada
Publisher: American Meteorological Society
Abstract: The rate of precipitation increase with elevation, termed the orographic precipitation gradient (OPG), is critically important for hydrologic forecasting in mountain basins that receive both rain and snow. Here, the following ...
Meteorological Characteristics and Overland Precipitation Impacts of Atmospheric Rivers Affecting the West Coast of North America Based on Eight Years of SSM/I Satellite Observations
Publisher: American Meteorological Society
Abstract: The pre-cold-frontal low-level jet within oceanic extratropical cyclones represents the lower-tropospheric component of a deeper corridor of concentrated water vapor transport in the cyclone warm sector. These corridors ...
Using CERES SYN Surface Irradiance Data as Forcing for Snowmelt Simulation in Complex Terrain
Publisher: American Meteorological Society
Abstract: he benefit of using solar and longwave surface irradiance data from NASA?s Clouds and the Earth?s Radiant Energy System (CERES) synoptic (SYN) satellite product in simulations of snowmelt has been examined. The accuracy ...
High-Elevation Precipitation Patterns: Using Snow Measurements to Assess Daily Gridded Datasets across the Sierra Nevada, California
Publisher: American Meteorological Society
Abstract: ridded spatiotemporal maps of precipitation are essential for hydrometeorological and ecological analyses. In the United States, most of these datasets are developed using the Cooperative Observer (COOP) network of ...
