Über diese Vorhersage

50 ECMWF-Wellenmitglieder mit 0.1° zur Untersuchung unsicherer Wellenhöhen, Perioden und Richtungen bis 15 Tage.

Was ist ECMWF IFS?

IFS steht für Integrated Forecasting System. Das Europäische Zentrum für mittelfristige Wettervorhersage (EZMW, englisch ECMWF) entwickelt es in Zusammenarbeit mit Météo-France. Datenassimilation verbindet Beobachtungen mit dem Modellzustand; physikalische Gleichungen beschreiben die weitere Entwicklung des Erdsystems. Atmosphäre, Land, Ozean und Wellen tauschen dabei Informationen aus. Diese Produkte gehören zur kurz- und mittelfristigen Vorhersage bis 15 Tage. Daneben entwickelt das EZMW die auf maschinellem Lernen basierende AIFS-Familie. ECMWF-Dokumentation.

Wofür sich dieses Produkt eignet

Das Wellenensemble überträgt alternative IFS-Wetterszenarien in das gekoppelte ecWAM-Modell. Es zeigt, wie Unsicherheit in der Sturmentwicklung den Seegang verändert. Verfügbar sind Mitglieder 1–50; der Wellenkontrolllauf ist separat. Vergleichen Sie Verläufe, um Beginn und Dauer geeigneter Einsatzbedingungen zu beurteilen. ECMWF-Dokumentation.
