Prediction accuracy of the Analog Ensemble depends on the quality of analogs. Presumably, better analogs will generate better predictions. In an operational model, it is likely that the historical forecasts in the near past are the most similar to the current forecast. Therefore, in operational mode, as each day passes, it is added to the historical repository.
This article shows an example of how to use
RAnEn with an operational search. It is strongly suggested to go over the demo 1 prior to this tutorial.
