MESOSCALE STRUCTURE OF THE ATMOSPHERE IN REGIONS OF CLEAR-AIR TURBULENCE. VOLUME 1

Abstract

The mesoscale structure of the atmosphere in regions of Clear-Air Turbulence (CAT) is investigated by means of aircraft observations of wind, temperature, and ozone obtained in the upper troposphere and in the lower stratosphere. Analysis from five CAT missions are shown, including vertical cross sections normal to flow patterns and also detailed vertical 'soundings' of wind, temperature, and the Richardson number. A verification is obtained at intervals of 1000 ft between the occurrence of CAT and a Richardson criterion of 0.5. Over 70 percent of the 149 CAT cases are correctly specified by the criterion.
