Synoptic events during MOSAiC and their Forecast Reliability in the Troposphere-Stratosphere System

Summary

SynopSys exploits routine meteorological weather observations from the MOSAiC expedition, remote sensing data products, and meteorological forecast data to detect and characterize synoptic events in the Arctic and evaluate their influence on mid-latitudes. We implement a diagnostic framework that will advance our knowledge on dynamical processes in the coupled troposphere-stratosphere system. A particular focus lies in the evaluation of enhanced predictive capability through a synergistic and unique set of measurements in the Arctic and a better representation of physical processes in weather forecast models. As well documented, the Arctic region is undergoing rapid change in a warming climate. This has many implications for mid-latitude climate and consequently on the future social, economic, and political development in both regions. Improving weather forecast taking into account the coupling of the Artic and mid-latitudes is thus essential.

Partner

SynopSys is a collaborative project involving Alfred Wegener Institute, University of Bremen and Deutscher Wetterdienst. The collaboration enables a unique integration of specific expertise in Arctic research, data analysis, remote sensing and numerical weather prediction.

Workpackages

SynopSys is structured in four work packages. Each of them serves as a main objective of the project.

Meetings

SynopSys members meet regularly to coordinate their progress and ideas. Here we list the past and future meetings of the whole consortium.

Next Meeting is planned for July/August, when all positions will be filled.
