¿Qué es ECMWF IFS?

IFS significa Integrated Forecasting System, o Sistema Integrado de Predicción. Lo desarrolla el Centro Europeo de Predicción Meteorológica a Plazo Medio (ECMWF) en colaboración con Météo-France. Integra observaciones mediante asimilación de datos y calcula la evolución del sistema terrestre con ecuaciones físicas. Sus componentes de atmósfera, suelo, océano y oleaje intercambian información. Estos productos cubren el corto y medio plazo, hasta 15 días; ECMWF también desarrolla la familia AIFS, basada en aprendizaje automático. Documentación de ECMWF.

Para qué sirve este producto

El ensemble de oleaje traslada los escenarios meteorológicos alternativos de IFS al modelo acoplado ecWAM. Permite evaluar cómo la incertidumbre de las tormentas cambia el estado del mar. GribStream ofrece los miembros 1–50 y mantiene el control de oleaje en otro dataset. Compara las trayectorias para estudiar el inicio y la duración de condiciones operativas favorables.
