Bonjour,
je donne l'explication en Français ;)

GFS c'est le modèle de prévision

ensuite la première ligne d'entete donne les date et heures des prévisions météo utilisées pour le calcul.
Donc la 1ère colonne donne l'heure de départ UTC (z = heure zoulou ou UTC).
Et il faut lire la ligne, en me basant sur les prévision meteo du jj.m hhz (colonne) en partant à la date et heure de cette ligne jj.m hh:mm, je fais le parcours en x heures, et ainsi de suite pour chaque colonne.

Je ne sais pas si ma formulation est bien claire ?

Bons vents avec zezo ;)
Eldian

GFS is the name of the computational forecast model.

12z means "weaher forecast with starting conditions based on observations at 12 hours UTC (noon) that day", data is ready few hours later.

There are other forecasts besides GFS, but they are either not global or very expensive.

"z" mean zoulou. zoulou is UTC. In France the summer time is in "bravo" (UTC+2), and the winter time is in "alpha" (UTC+1)
