The term microphone-scale in Météorologie and Océanographie indicates what occurs on a scale the individual Nuage or the local Vortex in the Océan, that is to say less than 2 km of diameter. They are thus the studies of the phenomena of very small scales like the movements in a Orage, the formation of the droplets of Pluie or the formation of the Tornade S.

With this resolution, the Navier-Stokes equations of the movement of the Fluide S are only approximations for which it is necessary to add negligible nonlinear terms to more large scales. Moreover, it is necessary to add additional equations to take account of the Thermodynamique phase shifts of the matter, Chimie of the components of the fluids, etc
