Weather-Disruption-Risk index at a point or airport (Sugra derived)
Conditions-based Weather-Disruption-Risk index (0-100 with a band) for any coordinate worldwide or any reporting airport, computed by Sugra from sovereign weather, aviation, wave and hazard surfaces. Glass-box: every factor returns its own sub-score, the dominant driver is named, and the full published threshold set is echoed so the number can be reproduced. This is NOT a delay probability - it scores how hostile the observed environment is to transport operations, and models no airline, air-traffic-control, mechanical or staffing cause.
