  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.
