ECMWF’s Integrated Forecasting System (IFS) was upgraded on 30 June 2020.

Cycle 47r1 improves global weather forecasts and substantially improves analyses and forecasts in the stratosphere. The upgrade brings many changes in data assimilation and Earth system modelling. It also introduces a new tropical cyclone wind radii product, which will facilitate the identification of wind-related hazards. 

Further information on IFS cycle 47r1 and its release can be found here.
