title17-08-2011 ECCC

The ECCC global ensemble prediction system was upgraded to version 2.0.2 on 17 August 2011.

The main changes included in this upgrade are:

  • The number of members in the ensemble Kalman filter is doubled from 96 to 192.
  • The resolution of the medium-range forecasts is changed from 100 to 66 km.
  • The model top is raised from 10 hPa to 2 hPa.
  • A new dynamical model, with a Charney-Phillips vertical grid, is used.

Further documentation of the operational upgrade can be found at http://collaboration.cmc.ec.gc.ca/cmc/CMOI/product_guide/docs/changes_e.html

title13-10-2021 ECMWF

The ECMWF forecast system IFS was upgraded to the version 47r3.

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.

title30-06-2020 ECMWF

The ECMWF forecast system IFS was upgraded to the version 47r1.

This cycle includes changes in the treatment of observations and 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.

New Metrics of Tropical Cyclone (TC) “size” will supplement the existing forecasts of TC track and intensity.

Full details can be found in Implementation of IFS Cycle 47r1 page.
