The University of Wyoming has gained notable recognition in the field of atmospheric sciences due in large part to its contribution through the Skew T-Log P diagrams, commonly known as Skew T plots. These charts are an essential tool for meteorologists and atmospheric researchers, as they offer a graphical representation of temperature, pressure, and moisture profiles in the atmosphere. The university’s online Skew T data access service is widely used by weather analysts, students, researchers, and professionals around the world. Understanding how this system works and its importance can offer valuable insight into meteorological research and weather forecasting accuracy.
Understanding the Skew T-Log P Diagram
Definition and Purpose
The Skew T-Log P diagram is a thermodynamic chart used to plot vertical profiles of atmospheric data obtained from radiosonde observations. It is called Skew T” because the temperature lines on the chart are skewed rather than vertical, and “Log P” refers to the logarithmic scale used for atmospheric pressure on the vertical axis. This structure allows meteorologists to analyze the stability of the atmosphere, identify cloud layers, and assess the potential for severe weather.
Why It Matters
These diagrams are crucial in forecasting thunderstorms, turbulence, freezing levels, and jet streams. By examining temperature and dew point profiles, forecasters can estimate levels such as the lifting condensation level (LCL), level of free convection (LFC), and equilibrium level (EL). The visualization helps interpret atmospheric processes more clearly than numerical values alone.

Meteorologists, educators, students, pilots, and weather enthusiasts around the world rely on this platform for its reliability and comprehensiveness. It supports various meteorological models and assists in comparing observational data with forecast output.
Key Features of the Skew T Charts
Visual Components
The standard University of Wyoming Skew T chart includes multiple critical lines and values that help interpret atmospheric profiles
- IsobarsHorizontal lines indicating constant pressure
- IsothermsDiagonal lines representing constant temperature
- Dry adiabatsIndicate the path of unsaturated air parcels
- Moist adiabatsShow the temperature change for saturated parcels
- Mixing ratio linesRepresent constant water vapor mixing ratios
Data Plotted
The Skew T includes actual observations such as
- Temperature and dew point
- Wind barbs at each pressure level
- Altitude in kilometers or feet
- Surface pressure and inversion layers
This information is essential for weather prediction, aviation safety, and climate studies.
