DIFFERENTIAL ADVECTION AS A FACTOR IN CLEAR-AIR TURBULENCE

Abstract

Clear-air turbulence observations made by accelerometer measurements have been correlated with six-hour forecasts of the change in vertical stability. The change in stability has been forecast by computing the six-hour horizontal temperature advection at two levels. By means of the Kolmogorov-Smirnov non-parametric test for cumulative distributions, a significant correlation has been shown to exist between the observations of turbulence and the forecast change in stability. However, no significance has been established regarding the magnitude of the turbulence.
