Pre-industrial forecasts of Storm Eunice (2022)

Title Pre-industrial forecasts of Storm Eunice (2022)
Description Forecasts using IFS EPS CY47R3 replicating operations (51 members, TCo639, ORCA025Z75). The ocean state has had a hydrostatically balanced estimate of anthropogenic influence (warming) since 1850-1900 removed. The CO2 concentration was set to 285 ppm. This experiment is part of a set of six experiments (each corresponding to a different initial climate state and initialisation date) that were used in "Event attribution of a midlatitude windstorm using ensemble weather forecasts", Ermis et al., 2024, https://doi.org/10.1088/2752-5295/ad4200. We acknowledge the use of ECMWF's computing and archive facilities in this research under the special project spgbleac, without which this work would not have been possible. If you are interested in using these data, please let us know by contacting nicholas.leach@physics.ox.ac.uk or shirin.ermis@physics.ox.ac.uk.
