The ECMWF model has been upgraded to the version 49r1 with major changes among many others: - assimilation of 2m temperature observations,
- Land-surface model updates,
- increased resolution and soft-recentering of the ensemble of data assimilations (EDA) and
- activation of the stochastically perturbed parameterisations (SPP) model uncertainty scheme in all ensemble configurations.
The main changes to S2S contribution from ECMWF are: - The re-forecasts frequency changed to every two days: 1/3/5/7/9/11/13/15/17/19/21/23/25/27/29/31 (excluding 29 February)
- The parameter CAPE (59) was discontinued and replaced by MUCAPE (228235). For consistency (in S2S), that parameter is still encoded as before (paramId=59).
The first realtime forecasts and on-the-fly reforecasts runs with the new cycle were on 13/11/2024 More details can be found in ECMWF Model and Implementation of IFS Cycle 49r1 |
