Request PDF | Energy balance and snowmelt drivers of a marginal sub‐alpine snowpack | Snowmelt from the seasonal snowpack in the Australian Alps is a . The energy balance of a glacial surface can describe physical melting processes. To expand the understanding of how glaciers in arid regions respond to climate change, the energy budget in the accumulation zone of the Laohugou Glacier No. 12 was measured. Input variables were meteorological data (1 June—30 September ) from an automatic weather Cited by:
Abstract Models of processes in the alpine snow cover fundamentally depend on the spatial distribution of the surface energy balance over areas where topographic variability causes huge differences in the incoming solar radiation and in snow depth because of redistribution by a spatial scale commensurate with that of the terrain, we want to know which areas are Cited by: Cover of Snow as it is published now is a diamond--well, maybe a turquoise--in the rough. I very much wanted to like Cover of Snow. I really did, and so despite my doubts continuing to mount as I read more and more, I persevered to the end, to the bitter end/5.
The energy balance at the snow-cover surface is calculated by means of different distributed energy balance models over a region of a few square kilometres, the spatial resolution being 25 m. The models include topographical effects on the radiation components of . surface energy exchanges at a continental, midlatitude alpine site in Colorado over a complete snowmelt season. Radiative energy fluxes are measured directly, and turbulent energy ex- changes are computed using an aerodynamic profile method. The overall role and importance of the individual components of the energy balance is described.

Tern using an energy balance approach over an alpine terrain was developed. With a digital elevation model (DEM), surface characteristics information and meteoCited by: It is likely that temperatures will increase over the next decades, influencing the snow cover patterns in alpine regions.
Because of the different physical properties of the snow cover compared to non-snow-covered surfaces, the energy balance is changing with an increase in temperature and with a consecutive decrease of the snow cover Cited by: Energy balance Energy balance investigations over an alpine snow cover were performed mainly in the European Alps and the North American Rocky Mountains.
Many of these studies were performed over snow-covered glaciers under. Therefore the present study aims at evaluating energy balance simulations over snow covered alpine terrain primarily with respect to their radiation components.
Using ExtAEB, an extended version of AEB, emphasis is put on the relevance of an explicit coupling to the snow cover as well as on shading and scattering effects by the surroundings Cited by: Climate and energy exchange at the snow surface in the Alpine Region of the Sierra Nevada: 2.
Snow cover energy balance. Authors. Abstract. A detailed evaluation of surface climate and energy exchange at the snow surface in a small alpine watershed, typical of much of the southern Sierra Nevada, is presented for the water year.

A computer model simulating snowmelt evolution and the spatial snowmelt pattern using an energy balance approach over an alpine terrain was developed.
With a digital elevation model (DEM), surface characteristics information and meteorological data as input, all radiation balance components, turbulent fluxes, precipitation, and finally snowmelt were modeled on a daily by: A field campaign was conducted in August toinvestigate the energy balance and the evapotranspiration in a high alpine region.
Measurements were carried out at two sites characterized by different physiographic conditions. Net radiation is the only energy source at both observation by: into the soil. These relationships, along with a snowcover depletion curve, are used to spatially distribute the energy that is used to thaw the soil (and hence lower the frost table) over the hillslope.

Snow cover energy balance. Abstract. A detailed evaluation of surface climate and energy exchange at the snow surface in a small alpine watershed, typical of much of the southern Sierra Nevada, is presented for the water by: Jenny Milchman is a suspense writer from the Hudson River Valley of New York State.
Her debut novel, COVER OF SNOW, was published by Ballantine/Random House in January and her follow up novel, RUIN FALLS, will be published in April /5(). In most alpine regions, the presence of snow controls the hydro-climatic situation over a great part of the year.
The delayed and long-lasting process of snowmelt guarantees a relatively well-balanced discharge regime of rivers in the spring and summer melting season, even if only a small part of their catchment includes high mountain by: 3.
An Approach toward Energy Balance Simulation over Rugged Terrain We develop a digital computer model, based upon equilibrium temperature theory, of the magnitudes of the components of the energy balance fm a mountainous topographic surjke.

The energy fluxes were studied over dry and melting snow covers. The beginning of snowmelt clearly coincides with the beginning of positive daily sums of net radiation. During snowmelt, net radiation is the dominant energy by: Eden Energy Medicine uses many techniques that Donna Eden has found over the decades and thousands of clients to work most effectively at bringing the 9 energy systems of the body back into balance.
Many of these techniques are gleaned from ancient healing traditions and many others Donna developed. In most environments where a seasonal snow cover is present, the radiation balance is the dominant energy source for snowmelt (e.g., Male and Granger ; Ohmura ; Aguado ).Unlike the snow cover in plains, alpine snow fields receive radiation not only from the sky, but also from reflection and emission of the surrounding by:.
We ran the SNOBAL snowmelt model over the 6 year energy balance record at the alpine and subalpine towers in the Senator Beck Basin Study Area, San Juan Mountains, Colorado, USA.
