Intermittency

In dynamical systems, intermittency is the alternation of phases of apparently periodic and chaotic dynamics.

In the apparently periodic phases the behaviour is not quite, but only nearly periodic. Thus, rather than a (truly periodic) series of values such as 2, 4, 2, 4, ... one might have something like 2.0001, 4.0003, 2.0002, 4.0001, 2.0003, 3.9999, 1.8715, 6.7486, ... where the first six values are apparently periodic but where the actually chaotic nature of the system becomes apparent after the value 3.9999 is reached.

Intermittency factor is the fraction of time that motion is turbulent, denoted $mu$.
