A general formula for the intermittency exponent fJ. is proposed to explore various normal cascades in a unified manner. The mean vorticity amplitude w ( l) of eddies of length scale l oheys an inverse-power law w(l) ~ l-a with 1> a;;;;0. The mean square L.'(t) of the relative distance of a pair of particles at time t is asymptotically given by L. 2 ( t) ~ t ¢ with </J = 2 / (a- fJ.) for L.(t)}> L(O). It is shown that Fujisaka and Mori's variational principle of maximizing an information entropy of intermittency leads to /1 + a = logz (2"ao_lJ with ao=a{fJ.=O). For the three-dimensional energy cascade for which a=(2+f1)/3, this leads to fJ. 0.341' " 1 / 3 and </J 4.56 in accordance with the previous resu...
