A renormalization group approach to estimation of anomalous diffusion in the unstable equatorial F region
Resumen
An expression is derived for the anomalous diffusion coefficient associated with collisional interchange turbulence in the equatorial F region ionosphere. Waves with ω ≪ Vin ≪ Ωi are considered. The calculation makes use of the renormalization group method, following closely that of Kichatinov [1985]. The calculation is applied to the problem of plasma waves in the equatorial F region ionosphere generated by the ionospheric interchange instability. Approximations appropriate for the geometry of that problem are incorporated into the calculation. Using a model spectrum of the irregularities based on in situ satellite observations, we calculate that the anomalous diffusion seen by large‐scale plasma waves can be 5 orders of magnitude larger than the ambipolar diffusion coefficient.
