Large-ensemble pre-industrial forecasts of the 2021 Pacific Northwest Heatwave

Title Large-ensemble pre-industrial forecasts of the 2021 Pacific Northwest Heatwave
Description Forecasts using IFS EPS CY47R2 replicating operations (TCo639, ORCA025Z75). In this experiment, 251 members are forecast, rather than the usual 51. 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.
