THE ASSOCIATION OF RICHARDSON'S CRITERION WITH HIGH LEVEL TURBULENCE

Abstract

Investigations have shown various meteorological parameters which could be associated with high level turbulence. Two of these parameters are strong vertical wind shear and low stability. These and the Richardson Number are analyzed with respect to geographical location, proximity to the level of maximum wind, proximity to the tropopause, and seasons. The purpose of this study is to find out under what conditions the correlation between high level turbulence and low Richardson Number was good and under what conditions the correlation was poor. It is found for the most part that using the Richardson Number as a predictor of high level turbulence appears to be more successful in the eastern half of the country.
