Snow Service Central Europe

چکیده
Information on snow cover and snow properties is an important factor for hydrology and runoff modeling. Frequent updates of snow cover information can help to improve water balance and discharge calculations. Within the frame of Polar View, snow products from multisensoral satellite data are operationally provided to control and update water balance models for large parts of Southern Germany. This snow service is described and results are presented. Example applications are given using the PROMET model in the mesoscale Alpine catchment of the Upper Danube. Through assimilation of the remote sensed information in the PROMET model, enhanced snow water equivalent distributions that can not directly be observed by remote sensing were calculated. Accurate snow storage simulations are a prerequisite to correctly simulate runoff during the melting phase.

Atmospheric Controls on Eurasian Snow Extent
Composite analyses, based on weekly snow-cover charts, temperature, sea level pressure, cyclone tracks and a rotated PCA of daily filtered 700 hPa geopotential height are used to examine relationships between the dominant modes of low-frequency atmospheric variability and mid-winter snow extent over the Eurasian continent. Two of the circulation modes examined have been identified previously an...
متن کاملChanging Northern Hemisphere Snow Seasons
Spatial and temporal patterns in the onset, offset, and length of the snow season across Northern Hemisphere continents are examined for the period from 1967 to 2008. Full snow seasons (FSS) and core snow seasons (CSS) are defined based on the consistency of snow cover within a location over the course of the cold season. Climatologically, the seasonal onsets of FSS and CSS progress more rapidl...
متن کاملConnecting European snow cover variability with large scale atmospheric patterns
Winter snowfall and its temporal variability are important factors in the development of water management strategies for snow-dominated regions. For example, mountain regions of Europe rely on snow for recreation, and on snowmelt for water supply and hydropower. It is still unclear whether in these regions the snow regime is undergoing any major significant change. Moreover, snow interannual va...

Heavy snowfall in the cold period will cause a lot of damages and troubles for society such as collapse of building installations, and confusions in road network and fuel distributions. Freezing event will also make worse the intensity of damages. Therefore, identifying the mechanisms of Atmospheric Circulation Pattern (ACP) which form the heavy snowfall and freezing events will certainly...
متن کاملShifting mountain snow patterns in a changing climate from remote sensing retrieval.
Observed climate change has already led to a wide range of impacts on environmental systems and society. In this context, many mountain regions seem to be particularly sensitive to a changing climate, through increases in temperature coupled with changes in precipitation regimes that are often larger than the global average (EEA, 2012). In mid-latitude mountains, these driving factors strongly ...
