DESCRIPTION:ECMWF upgrades its Integrated Forecasting System (IFS) on a re
 gular basis\, and one such upgrade\, to IFS Cycle 46r1\, was planned for 1
 1 June 2019. These upgrades enable the Centre to integrate the latest scie
 ntific advances into the IFS and to introduce new products.\n\nAhead of th
 e implementation of IFS Cycle 46r1\, Director of Forecasts Florian Pappenb
 erger gave two webinars\, on 15 and 16 May 2019\, to explain how the chang
 es will improve forecasts. He also presented new data and graphical produc
 ts to be made available\, including some case studies.\n\nThe upgrade brin
 gs major improvements in data assimilation – the combination of Earth sy
 stem observations with model information to define the initial conditions 
 for forecasts – as well as in modelling and the range of observations us
 ed. Together the changes result in substantially better forecasts across t
 he range of predicted values\, including near-surface weather variables su
 ch as wind and temperature. Product innovations include making the Extreme
  Forecast Index and Shift of Tails for weekly mean 2-metre temperature and
  one-week total precipitation available in the extended range.\n\nhttps://
