RISVegetation and Topographic Control of Wind-Blown Snow Distributions in Distributed and Aggregated Simulations for an Arctic Tundra Basin
Publisher: American Meteorological Society
Abstract: A finescale model of blowing snow is used to simulate the characteristics of snow cover in a low-Arctic catchment with moderate topography and partial shrub cover. The influence of changing shrub characteristics is ...

Problems Closing the Energy Balance over a Homogeneous Snow Cover during Midwinter
Publisher: American Meteorological Society
Abstract: pplication of the energy balance approach to estimate snowmelt inherently presumes that the external energy fluxes can be measured or modeled with sufficient accuracy to reliably estimate the internal energy changes and ...
Characteristics of the Near-Surface Boundary Layer within a Mountain Valley during Winter
Publisher: American Meteorological Society
Abstract: ithin mountainous regions, estimating the exchange of sensible heat and water vapor between the surface and the atmosphere is an important but inexact endeavor. Measurements of the turbulence characteristics of the ...
Estimates of Threshold Wind Speeds for Snow Transport Using Meteorological Data
Publisher: American Meteorological Society
Abstract: The threshold wind speed for snow transport is related to properties of the surface snowpack: snow particle bonding, cohesion, and kinetic friction. These properties are controlled by meteorological factors. A method is ...
Impact of Future Climate and Vegetation on the Hydrology of an Arctic Headwater Basin at the Tundra–Taiga Transition
Publisher: American Meteorological Society
Abstract: The rapidly warming Arctic is experiencing permafrost degradation and shrub expansion. Future climate projections show a clear increase in mean annual temperature and increasing precipitation in the Arctic; however, the ...
Physically Based Mountain Hydrological Modeling Using Reanalysis Data in Patagonia
Publisher: American Meteorological Society
Abstract: physically based hydrological model for the upper Baker River basin (UBRB) in Patagonia was developed using the modular Cold Regions Hydrological Model (CRHM) in order to better understand the processes that drive the ...
Sublimation of Snow from Coniferous Forests in a Climate Model
Publisher: American Meteorological Society
Abstract: Improved representations of snow interception by coniferous forest canopies and sublimation of intercepted snow are implemented in a land surface model. Driven with meteorological observations from forested sites in Canada, ...
Hydrological Responses of Headwater Basins to Monthly Perturbed Climate in the North American Cordillera
Publisher: American Meteorological Society
Abstract: AbstractHow mountain hydrology at different elevations will respond to climate change is a challenging question of great importance to assessing changing water resources. Here, three North American Cordilleran snow-dominated ...
Freeze–Thaw Changes of Seasonally Frozen Ground on the Tibetan Plateau from 1960 to 2014
Publisher: American Meteorological Society
Abstract: The freeze–thaw changes of seasonally frozen ground (SFG) are an important indicator of climate change. Based on observed daily freeze depth of SFG from meteorological stations on the Tibetan Plateau (TP) from 1960 to 2014, ...
