Skew-T Log-P diagrams(weather.rap.ucar.edu/upper). are not the most popular weather products perhaps since, at first glance, they appear confusing and hard to interpret. The diagrams are produced from atmospheric soundings, which are measurements of the vertical distribution of physical properties of the atmosphere.
As a pilot and not as a meteorologist, I find that these nomographs provide additional information about the state of the atmosphere by vertically slicing the atmosphere. Other than low-level obscuration such as fog, “nasty” weather manifests itself in the vertical. Of course, glider pilots use them extensively since an unstable atmosphere is a glider pilot’s dream. Let’s decipher these diagrams.
