AN IN-FLIGHT STUDY OF THE RELATION BETWEEN JET STREAMS, CIRRUS, AND WIND SHEAR TURBULENCE.

Abstract

An analysis of data from 414 weather research flights indicates a relationship between cirrus clouds associated with jet streams and the oc currence of wind shear turbulence. These data were obtained while flying as a crew member on Eastern Air Lines jet aircraft from December 1960 to May 1963. Detailed horizontal and vertical cross-sections for each flight and colored slides of cirrus cloud formations together with the corresponding surface and upper air data were analyzed. Four cloud pattern models have been developed to describe the areas of occurrence, thickness and horizontal extent of cirrus that have been found to produce significant turbu lence. The polar and subtropical jet streams have been classified by type and configuration to aid in determining the areas and intensity of turbulence in the cirrus. A fifth jet stream model indicates those situations in which cirrus does not form. (Author)
