title02-12-2021 ECCC forecast system change

The ECCC Global ensemble prediction system (GEPS) has been upgraded to the version 7  since 0Z run on with the main changes:

  • The version of the GEM model is upgraded to 5.1 with more advanced physics.
  • The number of vertical levels is increased from 81 to 85 for the data assimilation and from 45 to 85 for the forecast.
  • A Stochastic Parameter Perturbation (SPP) method is introduced to replace the Physics Tendency Perturbation (PTP).
  • 20 years hindcast period changed from 1997-2017 to 2001 to 2020 from

title13-10-2021 ECMWF forecast system change

New version of ECMWF IFS model (cycle 47r3) has been introduced at ECMWF since 6Z run on 2021-10-12. 

Cycle upgrade 47r3 will bring improvements to the assimilation and observations usage and a significantly improved physical basis for moist processes, necessary to facilitate further development of the Integrated Forecasting System (IFS) and future application at convection-permitting resolutions.
