Thirty‐three snowpack models of varying complexity and purpose were evaluated across a wide range hydrometeorological forest canopy conditions at five Northern Hemisphere locations, for up to two winter snow seasons. Modeled estimates water equivalent (SWE) or depth compared observations open sites each location. Precipitation phase duration above‐freezing air temperatures are shown be major influences on divergence convergence modeled the subcanopy snowpack. When considered collectively all...

Abstract Twenty-seven models participated in the Earth System Model–Snow Model Intercomparison Project (ESM-SnowMIP), most data-rich MIP dedicated to snow modeling. Our findings do not support hypothesis advanced by previous MIPs: evaluating against more variables and providing evaluation datasets extended temporally spatially does facilitate identification of key new processes requiring improvement model mass energy budgets, even at point scales. In fact, same modeling issues identified...
Abstract Many snow models have been developed for various applications such as hydrology, global atmospheric circulation and avalanche forecasting. The degree of complexity these is highly variable, ranging from simple index methods to multi-layer that simulate snow-cover stratigraphy texture. In the framework Snow Model Intercomparison Project (SnowMIP), 23 were compared using observed meteorological parameters two mountainous alpine sites. analysis here focuses on validation energy-budget...
Abstract. In alpine terrain, snow sublimation represents an important component of the winter moisture budget, representing a proportion precipitation which does not contribute to melt. To quantify its amount we analyze spatial pattern at ground, from canopy and turbulent suspension during wind-induced transport for high area in Berchtesgaden National Park (Germany), discuss efficiency these processes with respect seasonal snowfall. Therefore, utilized interpolated meteorological recordings...

Abstract Snow interception in a coniferous forest canopy is an important hydrological feature, producing complex mass and energy exchanges with the surrounding atmosphere snowpack below. Subcanopy accumulation ablation depends on effects of architecture meteorological conditions storage by stems, branches, needles. Mountain forests are primarily composed evergreen conifer species that retain their needles throughout year hence intercept snow efficiently during winter. Canopy-intercepted can...

Abstract. Seasonal snow cover is an important temporary water storage in high-elevation regions. Especially remote areas, the available data are often insufficient to accurately quantify snowmelt contributions streamflow. The limited knowledge about spatiotemporal variability of isotopic composition, as well pronounced spatial variation rates, leads high uncertainties applying isotope-based hydrograph separation method. stable signatures samples collected during two spring 2014 events at a...

Snow management, i. e., snowmaking and grooming, is an integral part of modern ski resort management. While the current snow cover distribution on slopes often well known thanks to usage advanced monitoring techniques, information about its future evolution usually lacking. Management-enabled numerical snowpack models driven by meteorological forecasts can help fill this gap.
