Skew-t

About Skew-t Android App

Skew-T Log-P diagrams are commonly used for weather analysis and forecasting. They graph weather balloon data to show the vertical profile of the temperature and dew point through the atmosphere.

See the following Finger Lakes Soaring Club web link for a great article describing how glider pilots use skew-t graphs to predict weather for a days flight.
