GribStream

NOAA AI Global Ensemble Forecast System Surface (AIGEFS Surface)

Codice GribStream: aigefssfc

Global native-grid GFS 2 meter temperature map with country boundaries
Representative global coverage: GFS 2 m temperature at its native 0.25 degree output spacing, with country boundaries overlaid. This coverage reference was generated from gfs for the aigefssfc page; available variables may differ.

Descrizione

AIGEFS Surface è l'ensemble globale NOAA/NCEP basato su IA per campi vicino alla superficie. Aggiunge incertezza probabilistica alla famiglia AIGFS.

In GribStream aigefssfc espone membri ensemble con variabili superficiali come vento, temperatura, umidità, punto di rugiada, pressione e precipitazione. È pensato per scenari, spread e probabilità, non solo per una singola traiettoria.

È utile per energia, rotte, logistica, gestione rischio e confronto con ensemble fisici come GEFS o IFS ENS.

Per struttura verticale usa AIGEFS Pressure. Per previsione IA deterministica usa AIGFS Surface.

APCP –Accumulated Precipitation (kg/m^2)
1 variant
NOAA GRIB2 Table 4.2-0-1

Accumulated precipitation represents the total water-equivalent amount of rain and snow during the output period. It is a primary field for hydrologic impacts and event totals.

  • Units: kg/m^2.
  • Use with the model time interval to interpret totals and compare to gauges.

DPT –Dew Point Temperature (K)
1 variant
NOAA GRIB2 Table 4.2-0-0

Dew point temperature is the temperature at which the air becomes saturated. It is a direct measure of moisture content.

  • Units: K.
  • When dew point is close to air temperature, fog or low cloud potential increases.

PRES –Pressure (Pa)
1 variant
NOAA GRIB2 Table 4.2-0-3

Pressure is the atmospheric pressure at the specified level. It is a fundamental mass-field variable for dynamics and thermodynamics.

  • Units: Pa.

PRMSL –Pressure Reduced to Mean Sea Level (Pa)
1 variant
NOAA GRIB2 Table 4.2-0-3

Pressure reduced to mean sea level is MSLP computed from surface pressure and temperature. It is used to locate highs and lows.

  • Units: Pa.

SPFH –Specific Humidity (kg/kg)
1 variant
NOAA GRIB2 Table 4.2-0-1

Specific humidity is the mass of water vapor per mass of air at the specified level. It is central to moisture transport.

  • Units: kg/kg.
  • Higher values indicate more atmospheric moisture and greater cloud or precip potential.

TMP –Temperature (K)
2 variants
NOAA GRIB2 Table 4.2-0-0

Air temperature is the thermal state of the atmosphere at the specified level. It influences density, stability, and energy exchange.

  • Units: K.

UGRD –U-Component of Wind (m/s)
2 variants
NOAA GRIB2 Table 4.2-0-2

U‑component of wind is the east‑west component of the horizontal wind. Combine with v for speed and direction.

  • Units: m/s.
  • Combine u and v components to compute speed and direction.
