This study uses a physically based snow-cover model to examine the influence of energy fluxes on northern Great Plains snow-depth decreases. Over a 25-year period during the month of February, the model is run for 19 stations distributed across
the region. The model estimates of radiative and convective fluxes along with temperature and dew point are compared with changes in the snow depth to determine the key factor or factors associated with midwinter snow-depth changes and its variability

A ten-year (1982-1992) assessment of the total water budget of the Chenab River at Akhnour. About 70 percent of the basin area is covered with snow in March/April which is reduced to ca. 24 percent in September/October. - (DWG)
This research examines how snow accumulation, and erosion processes associated with it, influences the distribution of vegetation. The studies were conducted on Peñalara Massif, in the centre of the Iberian Peninsula. A detailed vegetation map
space. The AA. examined the most unstable landforms, the areas with the sparsest vegetation and the zones that had the greatest snow accumulation.

This paper examines how snow plays a role in current erosive processes in a high mountain area (1800-2400 m a.s.l.) known as Peñalara, located in Spain's Central Range. The hypothesis maintains that snow becomes an important erosive factor when

Sound travels faster at higher temperatures and relative humidities. It can be heard at a greater distance with a temperature inversion or when the wind direction is toward the listener. Snow and water vapor absorb sound and thus decrease

is proved; a snow-line (ELA)-depression of 820-1250 m in relation to the present relief has been calculated. Modelling by means of those snow-line depressions and estimations of the precipitation provide ideas about surface heights, ice thicknesses and flow
behaviour of the ice sheet. The hypothesis of a global triggering of the ice age by the uplift of the subtropical Tibet up to above the snow-line motivates the investigations presented here.

are higher than those generally reported in other studies due to high thermal regime of area and incidence of snow cover at higher elevations. Because of variations in the lapse rates from station to station to season, author cautions in their use. - (SLD)

The historical to post-glacial glacier positions have been reconstructed from the recent glaciation history of selected examples. A chronological classification of the glacial events in phases can be defined by calculating the snow-line depression
of snow to be assessed for a number of periods. A strong correlation is evident between the glacial phases on land and the isotopic variations in cores from the Tyrrhenian Sea.
