API NOAA CFS Isentropic

Descrizione

CFS Isentropic espone campi su superfici isentropiche, cioè superfici di temperatura potenziale costante. È più specializzato dei normali livelli di pressione e serve a seguire trasporto e dinamica a grande scala.

Il dataset cfsipvf include variabili come vorticità potenziale, stream function (funzione di corrente) e lapse rate (gradiente termico verticale) quando disponibili nella fonte. Questi campi sono utili per analizzare masse d'aria, fronti, stabilità e flusso in quota.

In GribStream lo usi con gli stessi schemi API degli altri dataset: coordinate, griglie, intervalli temporali, /timeseries e /runs. La differenza è nel tipo di struttura atmosferica che scegli di interrogare.

Per campi atmosferici più generali su livelli standard, usa CFS Pressure. Per radiazione e superficie terrestre usa CFS Radiative Fluxes.

Caratteristiche principali:

Campi su superfici di temperatura potenziale costante per analisi del trasporto atmosferico.
Include vorticità potenziale, stream function (funzione di corrente) e lapse rate (gradiente termico verticale) per dinamica a grande scala.
Aiuta a seguire masse d'aria, struttura frontale, saccature in quota, stabilità e flusso del jet stream.
Completa CFS Pressure quando un prodotto richiede una vista dinamica più specializzata.

Risoluzione: Griglia globale da 1.0 grado.

Copertura temporale: Quattro run al giorno; previsioni fino a 5160 h, circa 215 giorni.

Usi principali: Dinamica dell'alta atmosfera, analisi del jet stream, trasporto di masse d'aria, aviazione, ricerca sulla vorticità potenziale, diagnostica frontale e contesto dinamico a orizzonte esteso.
