DESCRIPTION:\n\n\n\n\n\n\n\n\n#IFS47r1 \n\nThe new IFS Cycle 47r1 will be 
 implemented on 30 June 2020.  \n\nThis cycle includes changes in the tr
 eatment of observations\, improvements in the data assimilation and to th
 e model. Quintic vertical interpolation in the semi-Lagrangian advection 
 scheme has been introduced as well as the inclusion of a better surface a
 lbedo climatology making use of more data from the MODIS instrument. Furt
 her information on this new cycle is available at Implementation of IFS 
 Cycle 47r1.  \n\nPlease 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 thei
 r decoding software. For technical information see New Tropical Cyclone Wi
 nd Radii product.   \n\nAhead of the implementation of IFS Cycle 47r1\, 
 Director of Forecasts Florian Pappenberger explained the changes and how t
 hey will improve forecasts in a webinar on 27 May 2020 at 8.30 UTC and 28 
 May 2020 at 14.30 UTC. The webinars focused on verification\, technical ac
 cess to the test data and new parameters and products.\n\nThe upgrade bri
 ngs improvements in data assimilation\, including developments to the weak
  constraint 4D-Var and improvements to the initial balance of the analysis
 . In the model\, more accurate vertical interpolation is the advection sch
 eme significantly improves stratospheric performance in a cost-effective m
 anner\, and changes to surface drag over the ocean at high wind speeds imp
 rove the wind-intensity relationship for tropical cyclones. These and othe
 r developments were described.\n\n\n\n\n\n\n\n\nhttps://events.ecmwf.int/e
