Skew-T Diagram Basic Guide: Temperature, Dew Point, Wind, CAPE, and Layers
A beginner explanation of skew-T diagrams and how meteorologists use them to assess moisture, instability, wind, and storm potential.
Quick answer: A skew-T diagram shows a vertical profile of the atmosphere, including temperature, dew point, wind, and stability.
Vertical profile
Instead of showing a map, a skew-T shows how conditions change with height above one location.
That helps reveal layers that surface observations cannot show.
Storm ingredients
Meteorologists use skew-Ts to evaluate moisture, instability, capping, wind shear, freezing levels, and cloud layers.
These ingredients affect severe storms, snow, fog, and fire weather.
Beginner focus
Start by comparing temperature and dew point lines, then look at winds with height.
Advanced parameters should be read in context.
