Welcome to CWG


After 10 years of MSG operations, a number of applications in the area of severe convective storm detection and nowcasting have been developed by various users. The focus of this working group is to have a comprehensive inventory of the available applications in this field, with the aim to get deeper insight into the differences and commonalities of the available techniques and products, and their specific area of application.

The Convection Working Group is an initiative of ESSL, EUMETSAT and its member states.

Golden Case - 15 August 2010


The storms, which occurred on the 15th August 2010 in parts of central and eastern Europe, were interesting from many aspects, some of which are described in this test case.

Given the highly variable appearance and characteristics of these storms, this date was selected as the second CWG golden case, to be examined in detail, as well as used to test various convection-related algorithms.

Best Practise Document


John Mecikalski and Kristohper Bedka have made a big effort to write and compile the "Best Practice" document, describing relevant convection nowcasting methods.

Download this PDF and take note of the methods they describe! The intention is that this document is a living document and you are strongly encouraged to add sections to it, describing alternative nowcasting methods.

25 Oct 2011 - Overshooting Tops

Supported by the international training project EUMeTrain, young researcher Petra Mikus (DHMZ) did an impressive research on a satellite based method to detect overshooting tops and the impact this can have for nowcasting. Her research was presented at the Convection Week, at the EUMETSAT conference and the ECSS conference.

You are welcomed to take note of this research in this PDF.

20 Oct 2011 - Final Minutes - Mallorca Meeting

The final minutes to the CWG meeting in Palma de Mallorca are now available. Thank you for the comments and suggestions.

30 Jun 2011 - Best Practise Document

John Mecikalski and Kristohper Bedka have made a big effort to write and compile the “Best Practice” document, describing relevant convection nowcasting methods.

Download and take note of the methods they describe! The intention is that this document is a “living” document and you are strongly encouraged to add sections to it, describing alternative nowcasting methods. The "Best Practice document" and your contributions will be a topic at the next CWG meeting during the ECSS Conference in Mallorca.
