Skew-T Procedure
In the absence of significant air mass changes during the warm season, a single-sounding method may be employed to infer turbulence in convective clouds. The so-called Eastern Airlines Method is an empirical method developed from pilot reports of turbulence and analyzed soundings.
Procedure:
Delta-T (°C) Turbulence Intensity 0 - 3 Light 4 - 6 Moderate 7 - 9 Severe >9 Extreme
