Skew-T Log-P Reader
Estimate atmospheric stability parameters from surface observations and upper-air data. Calculates CAPE, LCL, LFC, and Lifted Index using simplified thermodynamic profiles.
Inputs
Results
CAPE
1,121 J/kg
Stability Category
Extremely Unstable
How to Use This Calculator
- Enter Surface Temperature (°C), Surface Dewpoint (°C), and Surface Pressure (mb).
- Input 500 mb Temperature from a sounding dataset or model output.
- Review CAPE (J/kg), LCL Pressure (mb), and LFC Pressure to characterize atmospheric instability.
- Check Lifted Index: below -6 = extremely unstable, -3 to -6 = moderately unstable, above 0 = stable.
- Use Equilibrium Level and parcel temperatures to estimate storm-top height and convective potential.
