Abstract : The probability of Clear Air Turbulence (CAT) significantly increases during flights above frontal lines at the surface of earth and almost does not depend on the features of surface pressure field and barometric tendency. The probability of CAT depends on a change in the geopotential height at flight level. However, this dependence is ambiguous and is determined by the form of the synoptic model. (Author)
