N2 - Using velocity data obtained in the atmospheric surface layer, we examine Kolmogorovs refined hypotheses. In particular, we focus on the properties of the stochastic variable V=u(r)/(rr)1/3, where u(r) is the velocity increment over a distance r, and r is the dissipation rate averaged over linear intervals of size r. We show that V has an approximately universal probability density function for r in the inertial range and discuss its properties; we also examine the properties of V for r outside the inertial range.
