ifswave0p1 · Altezza significativa delle onde in metri. Esempio storico: ciclo del 20 ottobre 2026 alle 12 UTC; valido il 30 ottobre alle 12 UTC (+240 h). Rappresentazione con la cella più vicina sulla griglia da 0.1°. Fonte: ECMWF, CC BY 4.0; grafico: GribStream.

Informazioni sulla previsione

Onde globali ECMWF a 0.1°: altezza significativa, periodi e direzione dal componente ecWAM di IFS, fino a 15 giorni.

Che cos’è ECMWF IFS?

IFS significa Integrated Forecasting System, il sistema integrato di previsione. Il Centro europeo per le previsioni meteorologiche a medio termine (ECMWF) lo sviluppa in collaborazione con Météo-France. Assimila le osservazioni e calcola l’evoluzione del sistema Terra mediante equazioni fisiche, con scambi tra atmosfera, suolo, oceano e onde. Questi prodotti coprono il breve e medio termine, fino a 15 giorni; ECMWF sviluppa anche la famiglia AIFS, basata sull’apprendimento automatico. Documentazione ECMWF.

A cosa serve questo prodotto

Il controllo delle onde proviene da ecWAM, accoppiato a IFS. Simula crescita, propagazione e dissipazione dell’energia ondosa per frequenza e direzione. Descrive sia il mare generato dal vento locale sia le onde lunghe provenienti da tempeste lontane, con una traiettoria per la pianificazione marina. Documentazione ECMWF.
