RISInterrelationships among Snow Distribution, Snowmelt, and Snow Cover Depletion: Implications for Atmospheric, Hydrologic, and Ecologic Modeling
Publisher: American Meteorological Society
Abstract: Local, regional, and global atmospheric, hydrologic, and ecologic models used to simulate weather, climate, land surface moisture, and vegetation processes all commonly represent their computational domains by a collection ...
Representing Subgrid Snow Cover Heterogeneities in Regional and Global Models
Publisher: American Meteorological Society
Abstract: To improve the depiction of autumn through spring land?atmosphere interactions and feedbacks within regional and global weather, climate, and hydrologic models, a Subgrid SNOW Distribution (SSNOWD) submodel that explicitly ...
Local Advection of Momentum, Heat, and Moisture during the Melt of Patchy Snow Covers
Publisher: American Meteorological Society
Abstract: A numerical atmospheric boundary layer model, based on higher-order turbulence closure assumptions, is developed and used to simulate the local advection of momentum, heat, and moisture during the melt of patchy snow covers ...
Winter Precipitation Patterns in Arctic Alaska Determined from a Blowing-Snow Model and Snow-Depth Observations
Publisher: American Meteorological Society
Abstract: A blowing-snow model (SnowTran-3D) was combined with field measurements of end-of-winter snow depth and density to simulate solid (winter) precipitation, snow transport, and sublimation distributions over a 20?000-km2 ...
A Meteorological Distribution System for High-Resolution Terrestrial Modeling (MicroMet)
Publisher: American Meteorological Society
Abstract: An intermediate-complexity, quasi?physically based, meteorological model (MicroMet) has been developed to produce high-resolution (e.g., 30-m to 1-km horizontal grid increment) atmospheric forcings required to run spatially ...
A Distributed Snow-Evolution Modeling System (SnowModel)
Publisher: American Meteorological Society
Abstract: SnowModel is a spatially distributed snow-evolution modeling system designed for application in landscapes, climates, and conditions where snow occurs. It is an aggregation of four submodels: MicroMet defines meteorological ...
Revisiting the Global Seasonal Snow Classification: An Updated Dataset for Earth System Applications
Publisher: American Meteorological Society
Snow–Ground Interface Temperatures in the Kuparuk River Basin, Arctic Alaska: Measurements and Model
Publisher: American Meteorological Society
Abstract: Air and snow?ground interface temperatures were measured during two winters at 33 stations spanning the 180-km-long Kuparuk basin in arctic Alaska. Interface temperatures averaged 7.5°C higher than air temperatures and ...
The Influence of Air Temperature Inversions on Snowmelt and Glacier Mass Balance Simulations, Ammassalik Island, Southeast Greenland
Publisher: American Meteorological Society
Abstract: In many applications, a realistic description of air temperature inversions is essential for accurate snow and glacier ice melt, and glacier mass-balance simulations. A physically based snow evolution modeling system ...
A Seasonal Snow Cover Classification System for Local to Global Applications
Publisher: American Meteorological Society
Abstract: A new classification system for seasonal snow covers is proposed. It has six classes (tundra, taiga, alpine, maritime, prairie, and ephemeral, each class defined by a unique ensemble of textural and stratigraphic characteristics ...
