Stratospheric turbulence and vertical effective diffusion coefficients
Abstract
Computations of the observed frequency distribution of the magnitudes of vertical shears of horizontal winds between 5 and 20 km altitude are reported. The probability distribution of turbulent layers for various values of vertical thickness is discussed. An effective verticaldiffusion coefficient, Ke, is estimated from a simple model using this empirical turbulence probability distribution. Specifically, the effect of clearair turbulence upon vertical transport is calculated, using a model consisting of a vertical column of thin, randomlyspaced mixing (turbulent) layers separated by thick nonmixing atmospheric layers.
