Planned IFS upgrade - extended-range forecasts

Extended-range forecasts to be recast in next model upgrade

In the next upgrade of ECMWF’s Integrated Forecasting System, extended-range forecasts will have 101 instead of 51 ensemble members and will run more frequently than before, at a consistent horizontal resolution of 36 km.
