...). This temperate latitude mountain permafrost is most likely found where annual mean air temperatures are ~0 °C or negative, snow cover thicknesses are relatively thin, and solar radiation input is low. This suggests high, windswept, north-facing slopes and ridges. An example is Niwot Ridge at an elevation of 3500...

... as observe geomorphic features related to snowmelt in the western United States. Annual snow accumulation in the higher elevations in the western United States provides a critical source of water for irrigation, hydroelectric power generation, municipal water supplies, and recreation. Snowmelt, however, also...

Although summer precipitation is reduced in this region, the changes in seasonality of temperature lead to significant higher amounts of summer snowfall. The strengthened North Atlantic circulation does...

... seasons, Taiwan can be impacted by frontal cyclones as well. During the January 2003 GSA Penrose Conference in Taiwan, a strong winter frontal system hit the island while the attendees drove from west to east across the Central Mountain Range. Heavy rain changed to snow as they ascended the mountain roads...

...Shane J. Cronin; Vincent E. Neall; Jérôme A. Lecointre; Alan S. Palmer Abstract The first lahars of the 1995 Ruapehu eruptive sequence were generated by explosively ejected Crater Lake water, sediment, and juvenile material, which incorporated snow and ice to form “snow slurry” lahars...

Shallow subsurface flow, which consisted of infiltrated snow meltwater and premelt groundwater, contributed the most to streamflow. At the end...

...Ming-ko Woo; Richard Heron Abstract At the end of the winter, the channels of small, subarctic rivers in the coastal James Bay Lowland are filled with snow, river ice, and icing. The major processes associated with the breakup of these rivers include the melting of the snow cover and the resultant...

The model is based on the concept that for practical purposes the infiltration potential of frozen soils may be generally categorized as (1) restricted: impervious; (2) unlimited: capable of infiltrating the snow-cover water equivalent; and (3) limited: infiltration is governed by the snow-cover water...

... is sustained by various sources of water, including spring snowmelt, the melting of semi-permanent snow banks, glaciers, and rainfall. If spring melt dominates, a simple arctic nival regime results and if this is followed by summer glacier melt, a proglacial regime occurs. In some non-glacierized basins...
