Query: On different cascade-speeds for longitudinal and transverse velocity
  increments   We address the problem of differences between longitudinal and transverse
velocity increments in isotropic small scale turbulence. The relationship of
these two quantities is analyzed experimentally by means of stochastic
Markovian processes leading to a phenomenological Fokker- Planck equation from
which a generalization of the Karman equation is derived. From these results, a
simple relationship between longitudinal and transverse structure functions is
found which explains the difference in the scaling properties of these two
structure functions.
