On 11 June 2019, ECMWF implemented a substantial upgrade of its Integrated Forecasting System (IFS). IFS Cycle 46r1 includes changes in the model and in the data assimilation procedure used to generate the initial conditions for forecasts. The upgrade has had a very positive impact on the skill of medium-range and extended-range ensemble forecasts (ENS) and medium-range high-resolution deterministic forecasts (HRES). It follows the implementation of IFS Cycle 45r1 in June 2018, which brought coupling to all ECMWF forecasts, from one day to one year ahead, by including ocean and sea-ice models in the HRES configuration.</p>
