NOAA GEFS Wave Prob API

Beschreibung

GEFS Wave Prob verwandelt Ensemble-Spread in Seegangswahrscheinlichkeiten. Statt nur eine vorhergesagte Wellenhöhe zu betrachten, können Sie fragen, wie wahrscheinlich konkrete operative Schwellen überschritten werden.

Dieser Ansatz ist für maritime Entscheidungen wichtig, weil die Kosten einer Unterschätzung von Seegang oft asymmetrisch sind. Schon eine moderate Wahrscheinlichkeit gefährlicher Bedingungen kann Routen, Arbeitsfenster oder Sicherheitsmargen verändern.

Das Produkt konzentriert sich auf Seegangsvariablen, einschließlich signifikanter Wellenhöhe, mit Wahrscheinlichkeitsvarianten nach Schwelle. Katalogwerte in info, etwa prob >3, bleiben exakt erhalten, weil sie Teil des API-Selektors sind.

In GribStream ergänzt gefswaveprob GEFS Atmos, wenn Ihr Produkt probabilistisches maritimes Risiko benötigt und nicht nur globale atmosphärische Bedingungen.

Wichtigste Merkmale:

Schätzt die Wahrscheinlichkeit, dass signifikante Wellenhöhe bestimmte Schwellen überschreitet.
Nutzt Ensemble-Spread, um maritimes Risiko zu quantifizieren, statt nur ein einzelnes Szenario zu liefern.
Läufe um 00, 06, 12 und 18 UTC mit Horizonten von 0 bis 384 h.
Ausgerichtet auf Seerouten, Offshore-Operationen, Küstenplanung und Analyse gefährlicher Seebedingungen.

Auflösung: Globales 0.25-Grad-Grid.

Zeitliche Abdeckung: Vier Läufe pro Tag, mit Horizonten von 0 bis 384 h.

Hauptanwendungen: Planung von Seerouten, Offshore-Operationen, Küstenmanagement, Hafenplanung, Wassersport, Seeversicherung und Warnungen auf Basis der Wahrscheinlichkeit, dass Seegang operative Schwellen überschreitet.
