“…Changes of snow cover stability in Poland are more or less in agreement with these high-latitude and highelevation areas in the Northern Hemisphere: the lastobserved snow cover in spring shifted in these areas earlier by 3-5 days/decade and the duration of the snow-free period increased by 5-6 days/decade in 1972-2000, primarily due to earlier snow cover disappearance in spring (Dye 2002).…”

“…Changes of the seasonal snow cover in the area of Poland as well as in the whole world are already quite well-known (e.g., Gutzler and Rosen 1992;Groisman et al 1994;Walland and Simmonds 1997;Brown 2000;Dye 2002). Poland is located within the pointed zone by Brown and Mote (2009) where seasonal mean air temperatures are in the range of −5°t o +5°C; these areas showed the largest decreases in snow cover duration during the 1966-2007 period due to their high sensitivity to climate changes (Brown and Mote 2009).…”

The seasonal stability of snow cover (ISS) was defined as a percentage ratio of the real and the potential snow cover duration in a winter season. Main results of the study are as follows: (1) alternately occurring periods of high and low values of the index of snow cover stability did not appeared simultaneously in mountainous and nonmountainous areas; (2) in the majority of Poland area both zonal and meridional components of the atmospheric circulation influence the ISS; however, in south the meridional air flow reveals the stronger impact, mostly due to the intensification of the southern advection by the foehn effect; and (3) changes of two or three indices describing atmospheric circulation explain up to 50 % of the ISS in Poland. The diminishing stability of snow cover in Poland corresponds with an increasing intensity of the advection from the western sector in winter in the second half of the twentieth century in Europe.

“…However, the snow-free period has also increased because the snowmelt date has advanced 9 -15 days in the last 30 years [Dye, 2002;Zhou et al, 2001;Serreze et al, 2000;Stone et al, 2002;Bamzai, 2003] due to the temperature increase observed at northern latitudes [Jones and Moberg, 2003]. In contrast, no particular trends have been found for the dates of snow onset [Bamzai, 2003;Dye, 2002], although Brown [2000] did show a widespread significant trend toward earlier dates of maximum snow depth over the 1955-1997 period in North America.…”

“…Gutzler and Rosen [1992] compared the evolution of two major atmospheric circulation indices, the Pacific North American pattern and the North Atlantic Oscillation, while Bamzai [2003] analyzed the role of the Arctic Oscillation. However, most studies on the spatial and temporal variability of snow cover in the Northern Hemisphere have focused on trends analysis [Brown, 2000;Dye, 2002;Smith and Saatchi, 2004], and those investigating the relationships with atmospheric circulation have mainly been carried out at the continent or country level [e.g., Bednorz, 2002;Kryjov, 2002;Schaefer et al, 2004;Hori and Yasunari, 2003]. …”

[1] This paper analyzes the main spatial patterns in the dates of snow cover disappearance variability over northern latitudes between 1988 and 2003. The dates of snow cover disappearance were calculated using satellite passive microwave data from the Special Sensor Microwave/Imager. Spatial and temporal patterns were obtained using principal components analysis in the S mode. We identified eight components, each representing a large region characterized by homogeneous interannual variability in the dates of snow cover disappearance. We found that atmospheric circulation, summarized by means of teleconnection indices, had an important impact on the date of snow cover disappearance for most of these regions. A role is played by the Arctic Oscillation in western Siberia, the spring east Atlantic/west Russian pattern in central Siberia, and the Pacific North American pattern in southern Canada, while the El Niño-Southern Oscillation phenomenon and the west Pacific pattern are significantly related to variability in the date of snow cover disappearance in the northernmost areas of America. For the regions where we found no relationship between the interannual variability in the date of snow cover disappearance and the teleconnection indices, a direct relationship with some spatial patterns of sea level pressures, which are not well summarized by the teleconnection indices, was found.

Snow cover is encountered over most of the Northern Hemisphere (NH) mid‐ and high‐latitudes during the winter season and over many mountainous regions of the world for extended periods. Snow cover is an important component of the climate system through its role in modifying energy and moisture fluxes between the surface and the atmosphere, and through its role as a water store in hydrological systems. Snow also plays critical roles in ecological and biological systems, and in nutrient and carbon cycling. This article provides an introductory overview of snow cover including: definition of terms (snowfall, solid precipitation, snow depth, snow density, snow water equivalent); a review of methods for measuring snow cover properties; a discussion of the processes and concepts involved in the spatial and temporal variability of snow cover; a look at avalanches and recent efforts to model these; and finally, a discussion of how snow cover is changing in response to global warming.
