[CRYOLIST] IUGG 2023: JC03 Snow/Ice-Atmosphere Coupling and Modelling at Convection and Snowdrift-Permitting Scales

Dear colleagues,

the IUGG deadline for abstract submission is approaching (14th February). Please consider submitting to the session JC03 about Snow/Ice-Atmosphere Coupling and Modelling at Convection and Snowdrift-Permitting Scales (full description below).

We will have the chance to have invited presentations by Prof. Valentina Radic (UBC, Canada) and Prof. Michael Lehning (EPFL, Switzerland). 

You can submit your abstracts here: https://www.iugg2023berlin.org/abstract-submission/

We look forward to seeing you in Berlin!

Best Wishes,

JC03 Coupling Processes Between the Atmospheric Boundary-Layer and Snow - Ice Surfaces: Modelling at Convection and Snowdrift-Permitting Scales (IACS, IAHS, IAMAS)

Convener(s): Richard Essery (UK,IACS)

Co-Convener(s): Vincent Vionnet (Canada, IACS), Tobias Jonas (Switzerland, IAHS), Rebecca Mott (Switzerland, IAMAS)

Description
This symposium addresses fundamental exchange mechanisms of mass and energy between the cryosphere and the atmospheric boundary layer in snow and ice 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 exchanges as well as complex atmospheric flow patterns modulated by complexities in topography. These processes strongly affect the evolution of seasonal snow cover, permafrost and glaciers, and drive snow and ice hydrology. Moves towards convection-permitting scales in numerical weather prediction have also brought benefits for resolving atmospheric flows and precipitation in mountainous topography, but coupled modelling at smaller "snowdrift-permitting" scales for which there can be significant redistribution of snow between model grid cells has not yet been so widely investigated. We invite contributions on, but not limited to, the following topics: modelling of turbulent fluxes to snow and ice surfaces in stable boundary layers; advection of energy to snow cover and glaciers, and impacts on snow and ice melt; orographically-induced precipitation and preferential deposition of snowfall; wind-induced snow transport and associated sublimation. Studies in level and mountainous terrains are welcome. We particularly encourage abstracts that propose advances in modelling techniques to represent the physics of coupling the atmospheric boundary layer to snow and ice surfaces, and in applications of high-resolution snow and ice mass balance modelling.
