ECMWF runs workshops and seminars as part of its core activities. These typically last a few days, and provide the opportunity to hear expert speakers at seminars, and collaborate with colleagues during workshops. Most events are for our Member and Co-operating States, however some are open to broader audiences. 

Workshops and Annual Seminar

Annual seminar

The annual seminar looks at progress in a particular area of numerical weather forecasting. A new focus is chosen each year. The event runs over the course of a week in early September and is broken down into a series of lectures, given by ECMWF staff and independent experts.

September 10-13 2018 Annual Seminar: Earth system assimilation
September 2-6 2019 Annual Seminar: Subseasonal and seasonal forecasting: recent progress and future prospects


Workshops cover a variety of aspects of the ECMWF operational and research activities. The discussions during these workshops have a substantial effect on the activity of ECMWF in many of the areas which have been taken as topics.

The workshops focus on specialist subjects related to climate monitoring, weather prediction and computing, and vary in length.
