ACSYS ATMOSPHERIC BOUNDARY LAYER AND SEA ICE INTERACTION STUDY
Project DescriptionFirst results obtained with the meso scale model METRAS show that small scale variations of the sea ice concentration can significantly influence the large scale transports of momentum, heat, and humidity. This concerns the surface fluxes and the vertical profiles of the fluxes in the atmospheric boundary layer. Based on these results and on airborne and ship based measurements (campaigns REFLEX, ARTIST, and ACSYS) improved parameterizations of fluxes over sea ice covered areas will be developed and tested. The influence of an inhomogenous sea ice concentration on the large scale transports of energy and humidity as well as the scale dependence of parameterizations will be further analyzed.
Another goal is the study of cloud formation over ice covered areas.
