Abstract
Distributions of the velocity-field helicity in the atmospheric boundary layer have been obtained from acoustic sounding data. The helicity of large-scale motions (0.3–0.6 m/s2) exceeds (by an order of magnitude) its independently measured turbulent values, which are close to helicity averaged over the layer (0.02–0.12 m/s2). In the absence of strong convection, there is good correlation between helicity and wind velocity squared at upper sounding levels of 400 to 600 m.
