Within GABLS (GEWEX Atmospheric Boundary Layer Study), inter-comparison studies focus on boundary-layer parametrisation schemes in use by numerical
weather prediction and climate models. This workshop will focus on two of these studies, one specific to surface-atmosphere interaction over mid-latitudes and the other one to polar
regions.
The DICE (Diurnal land-atmosphere Coupling Experiment) proposes a simple methodology for assessing the impact of atmosphere feedbacks by first assessing the individual components
constrained by observational data and then identifying changes due to coupling. This is based on data collected during CASES-99 field campaign.
The GABLS4 case aims at studying the interaction between the boundary layer and the surface in strong stability and during the diurnal transition focussing on the decrease of the
turbulence. For those topics, a surface with a low conductivity and a high cooling potential, such as snow (glacier), is more accurate and easier to initialize as there is no need of soil
moisture, vegetation type or soil characteristics. This case relies on observations from DomeC on the Antarctic plateau.
During the workshop, synthesis of both intercomparison exercises will be presented and specific studies related to each of the cases. The number of attendees is limited to 50 people,
therefore priority will be given to participants of the intercomparisons. A 60 euros fee will be asked for registration, it will include coffee breaks, lunches for the 3 days and a dinner
Thursday night as social event.
