In the solar and geodynamo so that resistive effects on the transport coefficients appear negligible altogether, regardless of the mean flow. 4. The role of higher spatial derivatives From a mathematical point of view the above treatment is unsatisfactory. The transport coefficients were found to diverge for spatial scales ᐉ smaller than (ητc)1/2, and these—although usually much smaller than the correlation length λc—are always present at some level. A physicist would argue that these scales are ‘irrelevant’ as we are not interested in the behaviour of the mean on very small scales.
