  A relation between intermittency and clustering phenomena in velocity field
has been revealed for homogeneous fluid turbulence. It is described how the
intermittency exponent can be split into sum of two other exponents. One of
these exponents (cluster-exponent) characterizes clustering of the
'zero'-crossing points in nearly Gaussian velocity field and another exponent
is related to the tails of the velocity probability distribution. The
cluster-exponent is uniquely determined by the energy spectrum of the nearly
Gaussian velocity field and entire dependence of the intermittency exponent on
Reynolds number is determined by the cluster-exponent.
