Radiation and Thermal Factors in the Ablation of Glaciers on the Southern Slope of Elbrus,   This study investigates the energy balance and ground thermal characteristics associated with frost penetration and snowpack development during the an The more exposed upper site had a meagre snowpack (Author: B. D. Fahey, R. D. Thompson. Mazurkiewicz et al. () found that the ground heat flux is an important component of the snow energy balance in the Pacific Northwest. On an annual time scale, ground heat flux contributions to melt ranged from % at the upper site and from % at the lower by: 8.

The energy balance of a melting snow cover 41 over snow have been, estimated by aerodynamic formulae for steady flow over an infinite, uniform surface. Departures from this ideal situation are always likely to occur. On the other hand, it is not known whether these departures are serious enough to make the application of these formulae questionable.   The surface energy balance in a small permafrost watershed near Fox, Alaska, was calculated for the snow melt period, which started in 30 March and ended on 22 April with the total disappearance of the snow by: uncertainties are introduced by changes in the snow surface during the melt period. In a companion paper we show how hourly snowmelt rates, calculated from the energy balance. Arolla Energy balance / snow melt model exercise - 4 - available for snowmelt: units of W m-2 are equivalent to J s-1 mEach hour you have s. The energy required to melt 1 kg of ice (the latent heat of fusion of ice) is approximately: J kg You can hence calculate the mass (kg) of snow melt per hour (and total over the day).

example, its high albedo has a dramatic impact on the surface energy balance, and as a result snowpack removal in the spring results in the rapid and dramatic change in surface energy fluxes. In addition, since the snow stored on the ground may represent 6 to 10 months of precipitation, the brief snow melt period represents a sudden release of water to the stream .   Because the melt rate is a term in the surface energy balance equation in which air temperature is involved in several terms, all energy balance information is summarily included in these factors. The variability of the PDD factor in time and space is analyzed qualitatively by Lang and Braun () and quantitatively by Braithwaite ().Cited by: We use cookies to offer you a better experience, personalize content, tailor advertising, provide social media features, and better understand the use of our services. 1-D ENERGY BALANCE SIMULATION Energy balance components (Figure 4) were simulated hourly for each stand during the snow melt period (Apr 1- May 25) using the above equation. Advective energy (energy supplied to the snow pack by rainfall) was not considered as it was not observed during the snow melt period. Additionally, internal snow pack.
