DESCRIPTION:\n\n\n\n\n\n\n#IFS47r1 \n\nECMWF upgrades its forecasting syst
 em on a regular basis\, and one such upgrade is currently planned for 30 
 June 2020. These upgrades enable the Centre to integrate the latest scient
 ific advances into its Integrated Forecasting System (IFS).\n\nAhead of th
 e implementation of IFS Cycle 47r1\, Director of Research Andy Brown expla
 ined the changes and how they will improve forecasts in a webinar on 21 A
 pril at 8:30 UTC and 22 April at 14:30 UTC.\n\nThe upgrade brings impro
 vements in data assimilation\, including developments to the weak-constrai
 nt 4D-Var and improvements to the initial balance of the analysis. In the 
 model\, more accurate vertical interpolation in the advection scheme signi
 ficantly improves stratospheric performance in a cost-effective manner\, a
 nd changes to surface drag over the ocean at high wind speeds improve the 
 wind–intensity relationship for tropical cyclones. These and other devel
 opments were described.\n\nFurther webinars are planned for 27 May at 8:30
  UTC and 28 May at 14:30 UTC with a focus on verification\, technical ac
 cess to the test data\, and new parameters and products.\nA list of what i
 s different in IFS Cycle 47r1 is provided on the implementation page for f
 orecast users\, where regular updates on this upgrade will be posted.\n\n\
