Changes in snow depth in Norway during the period 1961–2010
Observed trends in annual maximum snow depth (SD) in Norway are analyzed and examined in the context of changes in winter climate from 1961 until today. Trends are evaluated for the 50-year period (1961–2010) and for three 30-year periods (1961–1990, 1971–2000, 1981–2010). The analyzed dataset is the most extensive and geographically representative for the country so ...

Spatial and temporal characteristics in streamflow-related hydroclimatic variables over western Canada. Part 2: future projections
Much of the freshwater in western Canada originates in the Rocky Mountains as snowpack. Temperature and precipitation patterns throughout the region control the amount of snow accumulated and stored throughout the winter, and the intensity and timing of melt during the spring freshet. Therefore, changes in temperature, precipitation, snow depth, and snowmelt over western Canada are examined ...

What does Vienna’s water supply have to do with the snow depth of the Alps?
The water supply of the city of Vienna stems from high-source water pipelines of the Lower Austrian-Styrian Alps. Here, snow depth measurements play a major role. In the following, we explain, why this is so relevant and how it is monitored… The snow depth is not only important in ski resorts. Experts estimate that up to 50 percent of annual precipitation falls as snow in the Austrian ...

Weather SDM: estimating snow density with high precision using snow depth and local climate
Snow density is an important measure in hydrology used to convert snow depth to the snow water equivalent (SWE). A model developed by Sturm, Tara and Liston predicts the snow density by using snow depth, the snow age and a snow class defined by the location. In this work this model is extended to include location and seasonal weather-specific variables. The model is named Weather Snow Density ...

What does Vienna’s water supply have to do with the snow depth in the Alps?
Lots of snow, but only a few measuring stations Where most of the snow falls, which is the case in difficult-to-reach mountains, there are exceedingly few measuring stations. Experts estimated that up to 50 percent of the annual precipitation in Austria is expected to be snow in the Austrian Alps. Apart from individual mountain stations, many measuring devices are located in the valley floor to ...

A model for the snow water equivalent derived from stratigraphy observations in northern Sweden
A new parameterization of snow water equivalent (SWE) based on snow depth (HS) has been developed from observations made in northern Sweden. When applying previous SWE parameterization from the Alps on observations from northern Sweden, the SWE values are systematically 20% lower. The new SWE parameterization is derived from a snow layer density regression model using snow layer hardness and ...

Analysis and modelling of snow bulk density in the Tyrolean Alps
An extensive collection of in-situ snow measurements is used to characterize snow conditions in the entire elevation range of the alpine area of Tyrol, Austria. Regularly observed snow station data are evaluated with respect to mean snow density–time curves of the period 1952–2010. Dependent on the observed snow depth (HS), the snow bulk density (ρ) is statistically modelled for different ...

Response of the Indian summer monsoon circulation and rainfall to seasonal snow depth anomaly over Eurasia
Several observational and modeling studies indicate that the Indian summer monsoon rainfall (ISMR) is inversely related to the Eurasian snow extent and depth. The other two important surface boundary conditions which influence the ISMR are the Pacific sea surface temperature (SST) to a large extent and the Indian Ocean SST to some extent. In the present study, observed Soviet snow depth data and ...

National Energy Technology Laboratory - USA
The National Energy Technology Laboratory site in Morgantown, West Virginia, USA, maintains a 150-foot free standing meteorological tower with data collection points at ground level, 33 feet, 75 feet, and at 150 feet. The data collected at ground level is Air Temperature, relative humidity, total rainfall, and snow depth. The other stations monitor wind direction and speed. Additionally, air ...

Lufft Snow Depth Sensor SHM31 in Use During Audi FIS Ski World Cup in 2019 - Case Study
The Alpine Ski World Cup of the International Ski Federation (FIS) is the international premier class of alpine ski tournaments. The FIS was founded in 1966 by a group of ski experts and the first World Cup was held in Winter 1967/68. Since then, it took place annually from October to March and at several locations worldwide. The current 53rd season started in Sölden, Austria and ends in ...

Groundwater recharge during spring thaw in the Prairie Pothole Region of North America
Snowmelt governs recharge in the Prairie Pothole Region of North America, but little is known about the soil at the time of recharge. Depth of snow, surface water, water table, and frozen soil were measured within a 2-ha landscape depression in Minnesota during spring thaw in 2000 and 2001. The water table rose by at least 1 m within 24 h after a pond formed within the landscape depression as a ...

Real-time Snowpack Temperature Profiling at Alaska’s Turnagain Pass - Case Study
CNFAIC recognized a need in their instrumentation network to monitor temperature and snow depths along Tincan Ridge as they were seeing high instances of avalanches in this popular backcountry area. The installed beadedstream solution provided them with real-time data of these parameters throughout the snow season, allowing for forecasters to better predict avalanche conditions and issue warnings ...

Evaluation of remotely sensed snow cover product in Central Asia
Central Asian countries depend highly on water resources from snow and glacier melt, which has to be studied thoroughly to estimate water availability. However, the observation network in Central Asia is poor to carry out such studies in detail. Observations from space using remote sensing techniques might fill this observation gap, which needs to be validated. Therefore, this study evaluates ...
