Making a forecast with AI is very efficient.  It requires only a single Graphics Processing Unit (GPU), takes less than a minute to run, and consumes a tiny fraction of the energy required for an IFS forecast.  This brings the prospect of more frequent and/or quite large, ensembles of AI forecasts.

Fig5Fig2.1.6.2.1-1: Forecasting process using AI for forecasts to T+72.  The forecast proceeds in six hour time steps with the output from one step presented as data to the next step.  Forecast data is available for six hour intervals out to T+72. The output data at each six hour forecast intervals is "decoded" from the AI grid points back to IFS resolution and may then be used for constructing charts of the parameters.
