Impact of cloud microphysical schemes of global and regional models onthe dynamics of Arctic cylones: comparison with airborne andCloudSat-CALIPSO data
Abstract
This post-doctoral research project aims to study cloud microphysic representations within summertime Arctic cyclones in numerical weather prediction systems, satellite observations and airborne observations. The approach will be based on several case studies. Different simulations of ARPEGE and AROME, which are the global and regional operational models developed at Météo-France, will be performed. Different set of cloud microphysical schemes will be tested to analyze their effect on the distribution of hydrometeors in clouds. Furthermore, a dynamical study will be realized on the implication of these microphysical perturbations on the heating rates and dynamics through the potential vorticity modification. To better assess the skills of the different forecasts and understand their differences, a comparison with Cloudsat-CALIPSO and airborne datasets gathered during the future field campaign RALI-THINICE in August 2021 will be made.
