Book Description
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.

Atmospheric Mesostructure and Clear Air Turbulence
Author: Gary J. Thompson
Publisher:
ISBN:
Category : Atmospheric models
Languages : en
Pages : 32
Book Description
The mesoscale atmospheric structure in and around regions of clear air turbulence (CAT) is investigated. It is shown that the formation and dissipation of clear air turbulence at several different altitudes is closely related to changes in the atmospheric mesostructure. The turbulence is located in the region of two sloping boroclinic zones and can be attributed to Kelvin-Helmholtz instability resulting from strong wind directional oscillations between these two stable layers. The meteorological sounding data reveal that the lower stable layer and the layer of strong directional oscillations undergo significant upward vertical displacement. The change in turbulence activity can be directly correlated with this motion, and the breakdown of the turbulence and the double stability structure occur almost simultaneously. (Author).

The Nature of the Mesoscale Wind and Temperature Structure During a Case of CAT

ISBN:
Category : Atmospheric temperature
Languages : en
Pages : 28
Book Description
An examination of the atmospheric mesostructure in regions of clear air turbulence by means of a special network of radiosondes revealed further evidence that Kelvin-Helmholtz (K-H) instabilities may be responsible for the formation of CAT. Significant CAT was encountered in the region of a relatively weak jet maximum. Rapid shear intensification occurred in this region, however, as the result of the development of large wind direction oscillations. A baroclinic zone was observed to form prior to and at the same level as the strongest turbulence. (Author).
