Objective: To collect detailed, high-quality observations related to adverse weather, for assimilation into models and validation of model output.
Work packages
Objective: Improved understanding, modelling and forecasting of mesoscale Arctic weather extremes.
Objective: To improve the treatment of cloud-radiation-sea-ice interactions in radiative transfer models for the Arctic.
Objective: To find out how past, present and future synoptic weather and climate conditions influence meso-scale extreme weather from Arctic fronts to polar lows.
Objective: To significantly improve forecasting skill of extreme weather events in the Arctic by: assimilation of new satellite and weather radar data; adopting improved process parameterizations from other WPs in the project; and using a high resolution ensemble prediction system (LAMEPS).
Objective: To co-ordinate the international THORPEX-IPY cluster.
