Transverse velocities, intermittency and asymmetry in fully developed   turbulence
  Using experimental transverse velocities data for very high Reynolds number turbulence, we suggest a model describing both formation of intermittency and asymmetry of turbulence. The model, called "bump-model" is a modification of ramp-model suggested earlier, S.I. Vainshtein and K.R. Sreenivasan, Phys. Rev. Lett., 73, 3085 (1994). The connection between asymmetry and intermittency makes it possible to study the latter with relatively low moments.
