Variability and trends in the duration and depth of snow cover in Poland in the 20th century

International Journal of Climatology, 2004
AbstractThis study investigates the changes and variability of the number of days with snow cover of ≥1 cm depth and the seasonal maximum snow cover depth at 66 meteorological stations throughout Poland, spanning a period of 50 (1948–49 to 1997–98) to 108 (1895–96 to 2002–03) winter seasons.

Duration of the Snow Cover and the Need for Artificial Snow—A Challenge for Management in Ski-Centres of Serbia

2018
The production and use of artificial snow has become necessary in most ski centres in Europe. The lack of snow creates problems in ski centres that were built without the prior valuation of natural factors. The survey covered winter tourist centres in Serbia, which are facing problems due to the shortening of the tourist season caused by the lack of ...

A Novel Snow Cover Occurrence Index (SCOI) for the Dynamics of Snow Duration and Glacier Extent in Mountainous Regions

IEEE Transactions on Geoscience and Remote Sensing
The snow cover occurrence index (SCOI), deffned as the ratio of the number of times that a pixel is classiffed as snow to the number of times that the pixel is observed in optical remote sensing data over a given year, can effectively mitigate the inffuence of clouds and holds great potential for extracting the annual snow duration and glacier extent ...

On the Use of Modis Snow Cover Product for Assessing Snow Extension and Duration Over the Po River Basin

SSRN Electronic Journal, 2013
Changes in climatic forcings on the Mediterranean area are foreseen by many global and regional models. Long-term temperature variations are expected to affect snow dynamics, thus impacting on the timing of the hydrologic response in Alpine catchments.

Spring snow cover duration and tundra greenness in the Lena Delta, Siberia

2022
The Lena Delta in Siberia is the largest delta in the Arctic and as a snow-dominated ecosystem particularly vulnerable to climate change. Using the two decades of MODerate resolution Imaging Spectroradiometer satellite acquisitions, this study investigates interannual and spatial variability of snow-cover duration and summer vegetation vitality in the ...

RECENT CHANGES IN THE SNOW COVER DURATION IN BULGARIA � PRELIMINARY RESULTS

SGEM International Multidisciplinary Scientific GeoConference� EXPO Proceedings
Snow cover is an indicator of the fluctuating climate, resulting from the change in the regime of winter precipitations and air temperatures. Our previous studies have revealed significant decreasing of the seasonal snow cover maxima and the precipitation amounts in the highest mountainous regions of Bulgaria, which is however not so strong at lower ...

Snow Cover Duration in Relation to Topography in the Loetschental, Switzerland

2009
In high mountain environments the spatial distribution of seasonal snow cover depends decisively on topography. Yearly repeated snow cover patterns during snow melt clearly indicate the impact of topography and influence significantly ecological and geomorphological patterns, as well as hydrological and climatic processes.

GIS-based modelling of spatial pattern of snow cover duration in an alpine area

Ecological Modelling, 2001
Snow cover duration patterns of an alpine hillslope (approximately 2 km 2 ) were derived using daily terrestrial photographic remote sensing. We have developed a suite of quantitative models in order to investigate the relative controls of topographic factors, the degree of non-linearity, the effect of seasonal differences and a possible influence of ...

Variability and Trends in the Duration and Depth of Snow Cover in Iran in Thirty Years

Journal of Earth Science & Climatic Change, 2014
This study investigates the changes and variability of the number of days with snow cover of ≥ 1 cm depth and the seasonal maximum snow cover depth at 28 meteorological stations throughout Iran, spanning a period of 30 (1981-82 to 2010-2011) to 15 (1996-97 to 2010-2011) Winter seasons.

Using inexpensive temperature sensors to monitor the duration and heterogeneity of snow‐covered areas

Water Resources Research, 2008
Small, self‐recording temperature sensors can be deployed quickly and inexpensively to monitor spatial and temporal patterns of snow accumulation and melt in complex environments. Burying these sensors slightly below the soil surface provides a record of the presence or absence of snow cover because near‐surface soil temperatures only experience ...
