ECMWF AIFS · Run 18Z 14 Oct · +0 h · Valid Wed 18Z 14 Oct

One ECMWF AIFS run — issued 18Z 14 Oct — played forward 6 hours at a time, from its analysis to 360 hours out.

Methodology

Nights and days pass as you step this run: that motion is the weather the run forecasts, not the forecast changing. Forecast Evolution is the other film — it holds one moment still and steps the runs, so the only thing that moves there is the model's mind. The colour scale is fitted to the whole run at once, so the same moment reads with more bands here than on the static ECMWF AIFS map; the field is identical. Six-hourly to 360 hours. ECMWF AIFS forecasts out to 360 hours. The frames past the one shown load on demand.

This map is drawn from model output we store ourselves, not from anyone's picture of it, and is based on data and products of the European Centre for Medium-Range Weather Forecasts (ECMWF). The per-city read of the same day — which cities the models are fighting about, and what the discussion makes of it — is on the national page. Every model's full forecast for any of these cities, or anywhere else, is in the beta: request an invite; it's free during the beta.
