European State of the Climate 2019: temperature anomaly chart

New report on European climate confirms 2019 as warmest year

A detailed report on the state of the European climate has confirmed that 2019 was the warmest year on record, continuing a trend that means 11 of the 12 warmest years in Europe have occurred since 2000. The report was released by the EU-funded Copernicus Climate Change Service implemented by ECMWF.
IFS Cycle 47r1 April 2020 webinar details

Webinars scheduled to explain upcoming changes in June’s forecasting system upgrade

ECMWF upgrades its forecasting system on a regular basis, and one such upgrade is planned for 30 June 2020. Director of Research Andy Brown will explain how the changes will improve forecasts in two webinars on 21 and 22 April 2020.
