WG1 Initiatives



1. DynForMed initiative

The initiative is dedicated to the Dynamics and operational Forecasts of Mediterranean cyclones (DynForMed). Platon Patlakas has replaced the previous initiative leader Philipp Zschenderlein, and he is currently collecting operational forecasts from participants, starting with a case study (the recent Medicane Ianos) to test the technical side and develop diagnostics, with the later goal to setup an operational website with current forecasts.


Named storm “Ianos”, Mediterranean hurricane-like storm, known as a “medicane”, as it approached western Greece, on Sept 17, 2020 (NOAA-20 satellite; credits: NOAA).

If you run (or have access to) operational forecasts and want to contribute, please contact

2. Medicane definition (joint with WG2)

The purpose of this initiative is the definition of what exactly is a “Mediterranean tropical cyclone”, aka Medicane. In the literature, the term “Medicane” has been adopted in different ways, depending on the purpose of the study and the tool adopted for the analysis. Marcello Miglietta is currently gathering the interested community members to start a discussion on how best to combine meteorological and climate point of views to converge towards a shared definition of a medicane.

Here is the leaflet on Medicanes: Mediterranean Hurricanes. Feel free to disseminate it among your peers.

3. 3T: tracks task team (cross-WGs)

Cyclone tracks are the most fundamental tool we use across WGs in the action, and here Manos Flaounas aims to coordinate the best use of tracking tools, and produce a database for the tracks, including information on their reliability. Participants apply their own tracking algorithm to the same dataset (ERA5) at 2 different resolutions (0.25° and 0.5°), 4 frequencies (hourly, 2, 3, 6 h). Usually, tracking methods provide only part of the tracks (segments) and miss other parts especially the initial phase. Putting them together, hopefully the complete tracks will be captured.

4. Model Intercomparison

The aim of this initiative is to perform a model intercomparison for case studies of Mediterranean cyclones, in order to better understand their dynamics and predictability, which are often linked. The rationale behind the model intercomparison is to look for a systematic response of changes in the representation of physical processes (e.g. convection, cloud microphysics, air-sea interactions) among a range of models and configurations. This initiative will exploit results from the “DynForMed” and “3T” initiatives and it is open to all modelling systems, including high resolution and coupled systems that are not available for operational forecasts.
