The effect of perturbation re-centring on ensemble forecasts At the European Centre for Medium-Range Weather Forecasts (ECMWF), perturbations from an ensemble of data assimilations (EDA) are re-centred on the deterministic high- resolution analysis to generate the initial conditions for the ECMWF ensemble. This study assesses how the perturbation re-centring affects the ensemble forecasts and what benefits starting directly from the perturbed EDA members may bring. |
