Large‐scale structures in the equatorial ionosphere and their connection to the generalized Rayleigh‐Taylor instability
Abstract
For the first time, electric field and density fluctuations have been simultaneously measured on the Communications/Navigation Outage Forecasting System satellite at large scales (>300 km). The ratio of their spectral power rises as k2, unlike scales from 20 m to 300 km where the ratio is independent of k. We suggest that gravity waves dominate these large scales and mix with density gradients via self‐generated electric fields to form δn/n0.
