À propos de cette prévision

Probabilités ECMWF à 0.1° de pluie et de rafales sur 24 heures et d’anomalies thermiques à 850 hPa, jusqu’à 15 jours.

Qu’est-ce que l’IFS du CEPMMT ?

IFS signifie Integrated Forecasting System, ou système intégré de prévision. Développé par le Centre européen pour les prévisions météorologiques à moyen terme (CEPMMT, ECMWF en anglais) en coopération avec Météo-France, il assimile les observations et simule l’évolution du système Terre à l’aide d’équations physiques. Ses composantes atmosphère, sol, océan et vagues échangent des informations. Ces produits couvrent le court et le moyen terme, jusqu’à 15 jours ; le CEPMMT développe aussi la famille AIFS, fondée sur l’apprentissage automatique. Documentation du CEPMMT.

À quoi sert ce produit ?

Ce produit exprime l’ensemble IFS en probabilités d’événements définis, par exemple au moins 25 mm de pluie en 24 heures. Les anomalies de température à 850 hPa décrivent un écart à la climatologie du modèle et repèrent les masses d’air inhabituellement chaudes ou froides. Documentation du CEPMMT.

10fgg10 –Probability of 24-hour maximum 10 m wind gust at least 10 m/s (%)
1 variant

Parameter ID 131100

ECMWF param DB

Percentage of the ensemble reaching the stated gust threshold over the preceding 24 hours.

  • Values are percentages (0–100). Daily event selectors use info=24h and are timestamped at the end of a rolling 24-hour window; consecutive windows overlap by 12 hours. Instantaneous anomaly selectors use empty info.
