Turbulence in the Ionosphere with Application to Meteor Trails, Ra¬dio Star Scintillation, Auroral Radar Echoes, and other Phenomena

摘要

The irregularities in electron density responsible for incoherent scattering of radio waves in the ionosphere are discussed on the assumption of isotropic turbulence in the neutral molecules, with allowance made for the effect of the earth's magnetic field on the associated irregularities in the density of the charged particles. The atmospheric model used is based on rocket observations, extrapolated upwards in height where necessary. Tentative formulas are deduced for the large eddies based on a nonstandard application of the Richardson number. For the small eddies the standard formulas of turbulence theory are used.
