NOAA Global Ensemble Forecast System - Atmospheric Mean (GEFS Atmos Mean)

GribStream-Code: gefsatmosmean

Beschreibung

GEFS Atmos Mean fasst das atmosphärische NOAA-Ensemble in mittleren Feldern zusammen. Statt ein einzelnes Mitglied zu wählen, liefert es eine zentrale Referenz aus dem Ensemble, nützlich wenn Sie eine stabilere globale Vorhersage benötigen.

Das Ensemble-Mittel ersetzt keine vollständige probabilistische Analyse. Nutzen Sie GEFS Atmos, wenn Sie einzelne Mitglieder, Perzentile, Spannen oder Überschreitungswahrscheinlichkeiten benötigen. Nutzen Sie gefsatmosmean, wenn Ihr Produkt eine stabilere Referenz für Temperatur, Wind, Niederschlag, Druck, geopotentielle Höhe und andere atmosphärische Felder benötigt.

In operativen Produkten kann diese Ausgabe als Referenz für vorhersageabhängige Entscheidungen dienen: Energie, Landwirtschaft, Logistik, Versicherungen, Hydrologie, Notfallmanagement und Risikomonitoring auf kontinentaler oder globaler Skala.

In GribStream behält gefsatmosmean die exakten Selektoren aus dem Katalog bei und kann mit denselben Punkt-, Grid-, /timeseries- und /runs-Mustern abgefragt werden wie die anderen GEFS-Datasets.

CAPE –Convective Available Potential Energy (J/kg)
2 variants
NOAA GRIB2

Convective Available Potential Energy (CAPE) quantifies buoyant energy available to rising air parcels. Larger values generally imply stronger potential updrafts and greater convective intensity.

  • Units: J/kg.
  • Often used with CIN and lifting mechanisms to assess thunderstorm potential.

CIN –Convective Inhibition (J/kg)
2 variants
NOAA GRIB2

Convective Inhibition (CIN) measures the energy barrier that must be overcome to initiate convection. More negative values indicate a stronger cap that can suppress storms.

  • Units: J/kg.
  • When CIN is weak and CAPE is high, convection is more likely.
