Boréales

[Elzéar]

Est-ce que les aurores boréales sont prévisibles et peuvent être signalées sur Windy (Nord comme Sud)?

Aurora events may be computed by taking into account different forecast model parameters and some extra-info, but not over long periods. They may be provided as nowcast only (i.e. next very short period say, 30 minutes), on very specialized sites, e.g. NOAA site.
Windy does not provide such a forecast, as Aurora parameter cannot is not (and cannot be) included in global weather hourly forecast grids it serves.
