Calibrated hail probability (%).
GribStream
Código GribStream: grefs
Probabilidades calibradas de tornados, granizo y viento dañino, combinando las condiciones atmosféricas de GEFS con las características de las tormentas de REFS.
Guía paralela de SPC_POST v3. NOAA prevé su implementación a partir del ciclo de las 12 UTC del 14 de octubre de 2026, con posibilidad de aplazamiento. SCN26-77.
GREFS y REFSCT: ciclos 00, 06, 12 y 18 UTC hasta +60 h. Ventanas de 4 h: finales horarios +4…60 h; REFSCT también ofrece ventanas de 1 h con finales +1…60 h. Los períodos completos conservan su duración exacta. En REFSCT comienzan en +0…59 h y terminan en el límite del día convectivo, como máximo en +60 h. GEFSCT: 00 UTC, +36…204 h; 12 UTC, +24…192 h; pasos de 24 h, ocho períodos que terminan a las 12 UTC.

Los valores son porcentajes de 0 a 100. Seleccione exactamente name, level e info en el inventario; no hay miembros individuales. forecasted_time marca el final: reste la duración seleccionada para obtener el inicio. En GREFS, para un ciclo REFS de las 12 UTC, GEFS lag 0h usa el GEFS de las 12 UTC y GEFS lag 6h el de las 06 UTC. Ambos usan el mismo ciclo REFS; el desfase indica la antigüedad de la entrada GEFS, no desplaza el período ni representa un retraso de publicación. Los ciclos no indican la hora de publicación. prob >0 es metadato GRIB de origen, no un umbral elegido por el usuario.

Se conservan los ciclos inicializados en los últimos dos días, como en los productos SPC anteriores. El plazo limita el historial de ciclos, no su alcance futuro: GEFSCT conserva sus ocho períodos diarios. Los identificadores HREF siguen separados y sus datos caducan según su retención de dos días.
