Data plotted on the skew-T diagram comprise temperatures, dewpoints, and wind speed and direction. Once plotted on the skew-T diagram, other unreported meteorological quantities describing atmospheric moisture and thermodynamic properties, such as humidity, stability, and other temperature characteristics, can be determined using graphical techniques.

This section describes techniques for determining various calculated quantities or parameters from sounding data plotted on the skew-T diagram.
