Summary
| Description |
English: The readings received by the rawinsonde are plotted for a meteorologist to examine. These vertical cross sections are plotted on what is referred to as Skew-T Log-P diagram. Among the many uses that meteorologists have for the Skew-T Log-P is the determination of the stability of the atmosphere and the potential for severe weather.
The Pink area represent the potential energy available for convection (CAPE). On top of the SKW_T, this images shows and hodograph of winds in the upper part and the wind direction are plotted on the right.
Français : Exemple d'utilisation du Skew-T pour pointer les données d'un radio-sondage de l'atmosphère. Le Skew-T est l'un des quatre diagrammes thermodynamiques utilisés pour analyser la structure thermique de l'atmosphère. Il utilise comme axes la température (T) versus le logarithme de la pression (P) dans un repère semi-logarithmique. Le nom vient l'aspect biaisé (skewed en anglais) de l'axe des températures. Il est utilisé pour pointer la température et le point de rosée provenant d'un sondage aérologique par radiosondes, d'un avion ou extrapolées par satellite.
Dnas cette image, en rose on voit l'Energie potentielle de convection disponible. ON y retrouve également un Hodographe des vents dans la partie supérieure et le pointage de la force et de la direction des vents à droite |
