Predictability and ensemble forecast systems

Dear participants,

Welcome to the e-learning section of the predictability and ensemble forecast systems course that will take place at the ECMWF headquarters in Reading.

This five-day course will tackle the challenge of making predictions from days to seasons ahead. The predictability of the atmosphere in the medium and extended range will be considered, including different aspects of the Earth system which give rise to predictability on longer time scales. Elements of a probabilistic forecast system as well as its calibration and verification will be presented.

The course itself is a combination of lectures, hands-on practicals and group discussion sessions, and suggested elements of pre-course study that will be presented and completed here on this e-learning platform.

Completion of these pre-learning activities recommended, since they will ensure you have the knowledge to get the most out of the practical parts of the course.

Please pay extra attention to the video tutorials that are needed for the preparation of the practical sessions.

Regarding your poster, please submit this via email to training@ecmwf.int

The final timetable of the course can be found here: https://events.ecmwf.int/event/545/timetable/


We look forward to welcoming you in Reading!

The ECMWF training team
