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.
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.

SynopSys is structured in four work packages. Each of them serves as a main objective of the project.
Detection and evaluation of events in measurements and forecast data
Assessment of forecast skill
Dedicated experiments with the ICON weather forecast system, e.g. data denial experiments
Exploring data driven methods
Extended analysis of events in reanalysis products reaching beyond the Arctic and the year of the MOSAiC expedition
Improvement and validation of remote-sensing ozone products
Analysis of interaction between stratosphere and troposphere
Development of diagnostics based on potential vorticity
Process-based analysis of the interaction between troposphere and stratosphere in a synoptic context
High resolution process studies with the ICON model in limited area mode
Attribution of forecast errors to potential model improvements
Sensitivity experiments with improved parametrizations in the ICON model
Assessment of improved forecast capabilities and their impact
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.
