Prediction of clear-air turbulence induced by short gravity waves

Abstract

A new auxiliary clear-air turbulence (CAT) predictor based on a triggering mechanism for clear-air turbulence, namely short (500m-20000m) gravity waves excited by shallow convection is considered. Case studies are presented in which the predictor is compared with other widely used CAT indices. One case is based on NWP (numerical weather prediction) model and other on on real sounding. Also comparison of real life sounding results with model generated ones is performed.
