Several horizontal flight segments from SESAME and
ALPEX are studied using structure functions and specral
analysis methods. Theoretical analysis of the relative
errors in structure function and correlation function in
the presence of large scale wave activity is presented. The
effect of stratification and shear on the -5/3 inertial
subrange is noted. The expected ratio of horizontal
velocity components for spectra and structure functions
(4/3) is observed in the inertial subrange. The observed
changes in the aspect ratio (defined as the square root of
ratio of vertical velocity structure function to the mean
horizontal velocity structure function) with turbulence
strength and stratification are analysed. / Graduation date: 1986
