The new IFS Cycle 47r1 will be implemented on 30 June 2020.
This cycle includes changes in the treatment of observations, improvements in the data assimilation and to the model. Quintic vertical interpolation in the semi-Lagrangian advection scheme has been introduced as well as the inclusion of a better surface albedo climatology making use of more data from the MODIS instrument. Further information on this new cycle is available at Implementation of IFS Cycle 47r1.
Please note that new metrics of Tropical Cyclone (TC) “size” will be made available to supplement the existing forecasts of TC track and intensity. We encourage users of these BUFR data to test their decoding software. For technical information see New Tropical Cyclone Wind Radii product.
Two webinars to introduce the model cycle have been organised:
Two additional webinars will take place at the end of May.
