CE ÎNSEAMNĂ PRESSURE GRADIENT ÎN ENGLEZĂ?
Gradient de presiune
În științele atmosferice, gradientul de presiune este o cantitate fizică care descrie ce direcție și la ce rată se schimbă presiunea cea mai rapidă în jurul unei anumite locații. Gradientul de presiune este o cantitate dimensională exprimată în unități de presiune pe unitate de lungime. Unitatea SI este pascal pe metru. Matematic, este obținut prin aplicarea operatorului del la o funcție de presiune a poziției.
Definiția pressure gradient în dicționarul Engleză
Definiția gradientului de presiune în dicționar este scăderea presiunii atmosferice pe unitate de distanță orizontală, prezentată pe o diagramă sinoptică prin distanța dintre isobare.
