Sobre este pronóstico

Oleaje global de ECMWF a 0.1°: altura significativa, períodos y dirección del componente ecWAM de IFS, hasta 15 días.

¿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 control de oleaje procede de ecWAM, el componente de ondas acoplado a IFS. Simula cómo crece, se propaga y se disipa la energía del oleaje según frecuencia y dirección. Describe tanto el mar de viento local como el mar de fondo procedente de tormentas lejanas, con una trayectoria para la planificación marina. Documentación de ECMWF.
