Dear Colleagues
we would like to draw your attention to the session 'Coupling Processes between the Atmospheric Boundary-Layer and Snow/Ice Surfaces: Observations and Modelling' (IACS Symposia, C10) at the IUGG 2015 General Assembly in Prague, June 23rd-28th 2015.
Deadline for abstract submission: January 31st 2015
C12 Coupling Processes between the Atmospheric Boundary-Layer and Snow/Ice Surfaces: Observations and Modelling
Convener: Rebecca Mott (Davos, Switzerland)
Co-conveners: Ruzica Dadic (Wellington, New Zealand), Vincent Vionnet (Grenoble, France), Michael Lehning (Lausanne/Davos, Switzerland)
Solicited speakers: Adam Winstral (Davos, Switzerland), Eric Bazile (Toulouse, France)
The symposium addresses fundamental exchange mechanisms between the cryosphere and the atmospheric boundary layer in snow-covered regions. The interaction between the near-surface atmosphere and the cryosphere can lead to significant spatial and temporal variations of momentum, mass- and energy exchange as well as complex atmospheric flow patterns. These processes strongly affect the temporal and spatial evolution of seasonal snow cover, permafrost, sea ice, vegetation or glacier melt. Furthermore, the continuous change of the snow/ice surface in time and feedbacks between the surface and the atmosphere have a very strong influence on the boundary layer, which is insufficiently understood and makes the problem of describing the joint atmosphere – cryosphere development one of the more challenging but worthwhile questions to address.
We invite contributions that consider boundary-layer meteorology, turbulent energy fluxes and mass exchanges in cryospheric environments. Examples include the treatment of turbulent fluxes in models and measurements, orographically-induced precipitation or wind-induced snow transport and sublimation. Both, model studies and experimental work are welcome. We particularly encourage abstracts that propose advances in a) modelling techniques to represent the physics of coupling the atmospheric boundary layer to snow and ice surfaces and b) observational techniques to explore complex processes that govern the mass and energy exchange between the lower boundary layer and the snow/ice surface.
Kind regards,
