Scaling exponents of the moments of the instantaneous velocity vector fluctuation increment, and its components and are compared with those of the temperature fluctuation increment, in the self-preserving region of a cylinder wake. Across the wake, scaling exponents compare more favorably to those of than do with mainly because is interdependent on and The agreement between scaling exponents of or with those of do not seem to depend on either the local mean shear or although the individual magnitudes of these exponents increase with and decrease with the local mean shear.
