Impact of distributed meteorological forcing on snow dynamic and induced water fluxes over a mid-elevation alpine micro-scale catchment

Autor: Aniket Gupta, Alix Reverdy, Jean-Martial Cohard, Didier Voisin, Basile Hector, Marc Descloitres, Jean-Pierre Vandervaere, Catherine Coulaud, Romain Biron, Lucie Liger, Jean-Gabriel Valay, Reed Maxwell

From the micro to mesoscale, water and energy budgets of mountainous catchments are largely driven by topographic features such as terrain orientation, slope, steepness, elevation together with associated meteorological forcings such as precipitation

Mineral dust and black carbon (BC) constitute the most important aerosols present in the atmosphere and cryosphere and have well known potential effects on regional and global climate. Upon their deposition they can impact snow albedo, snowpack evolu

Experimental study of katabatic jets over steep slopes: buoyancy effect and turbulence properties

Autor: Christophe Brun, Catherine Coulaud, Romain Biron, Martin Obligado, Hélène Guyard, Jean-Emmanuel Sicart, J.M. Cohard, Claudine Charrondière

Katabatic winds are gravity flows that develop over sloping terrain due to radiative cooling at the surface. They have been extensively studied, but experimental works have generally been performed over gentle slopes. Some recent papers (eg. [3]) foc

Residence time of nitrogen deposit in a nival subalpine catchment using the hyper-resolution ParFlow-CLM-EcoSLIM critical zone model

Autor: Alix Reverdy, Romain Biron, Aniket Gupta, Basile Hector, Didier Voisin, J.M. Cohard

Mountain regions represent a particular challenge for critical zone modelling as snowpack interacts with soils, vegetation, surface water and atmosphere and plays a primary role on the water transfers but also on the carbon and nitrogen cycles. Indee

International audience; Katabatic winds are very frequent but poorly understood or simulated over steep slopes. This study focuses on a katabatic jet above a steep alpine slope. We assess the buoyancy terms in both the turbulence kinetic energy (TKE)
