Abstract | Equatorial plasma depletions have signifcant impact on radio wave propagation in the upper atmosphere, causing rapid fuctuations in the power of radio signals used in telecommunication and GPS navigation, thus playing a crucial role in space weather impacts. Complex structuring and self-organization of equatorial plasma depletions involving bifurcation, connection, disconnection and reconnection are the signatures of nonlinear evolution of interchange instability and secondary instabilities, responsible for the generation of coherent structures and turbulence in the ionosphere. The aims of this work are three-fold: (1) to report the frst optical imaging of reconnection of equatorial plasma depletions in the South Atlantic Magnetic Anomaly, (2) to investigate the optical imaging of equatorial ionospheric intermittent turbulence, and (3) to compare nonlinear characteristics of optical imaging of equatorial plasma depletions for two diferent altitudes at same times. We show that the degree of spatiotemporal complexity of ionospheric intermittent turbulence can be quantifed by nonlinear studies of optical images, confrming the duality of amplitude-phase synchronization in multiscale interactions. By decomposing the analyses into North-South and East-West directions we show that the degree of non-Gaussianity, intermittency and multifractality is stronger in the North-South direction, confrming the anisotropic nature of the interchange instability. In particular, by using simultaneous observation of multi-spectral all-sky emissions (OI 630.0 nm and OI 777.4 nm emissions) from two diferent heights we show that the degree of non-Gaussianity and intermittency in the bottomside F-region ionosphere is stronger than the peak F-region ionosphere. Our results are confrmed by two sets of observations on different nights. |
