Cairngorm Mountain El Niño rank & forecast
Cairngorm Mountain ranks Under review SnowSure resorts — Tier A, +15% in strong El Niño winters.
Tier A — Prime El Niño terrain: Historically snowed much more than normal in strong El Niño winters (≥ +8% vs this resort’s own 30-year average).
Strong-event signal: +15% vs this resort's 30-yr avg
This resort carries no separate rank: its 30-year record is identical to Cairngorm, which is the ranked entry for this measurement. At ~31km resolution the reanalysis cannot resolve them as different mountains, so publishing both would be publishing one number twice.
