Causal Link of Longitudinal Plasma Density Structure to Vertical Plasma Drift and Atmospheric Tides \textendash A Review

This chapter reviews recent advances in our understanding of the characteristics and driving mechanisms of the longitudinal plasma density structure in the low-latitude F region. Various ionospheric observations have shown the development of a longitudinal wave-like pattern in plasma density. Typically, the wave number-4 (wave-4) pattern is pronounced during July\textendashSeptember, and the wave-3 pattern is pronounced during December\textendashJanuary. Variation of the longitudinal plasma density pattern with local time and season is causally linked to vertical plasma drift in the F region (or E-region dynamo electric fields). The wave-4 pattern is of special interest to the ionosphere-thermosphere community because this phenomenon is closely associated with the diurnal eastward propagating zonal wave number 3 tide (DE3). This idea is supported by observations of annual variation of the DE3 amplitude and diurnal variation of the DE3 phase that are consistent with the annual and diurnal variations of the wave-4 patterns in plasma density and dynamo electric fields. The connection of the ionospheric wave-3 pattern presumably to the diurnal eastward propagating zonal wave number 2 tide (DE2) further demonstrates the significant role of atmospheric tides in the formation of large-scale ionospheric structures. Formation of the large-scale longitudinal structures of the ionosphere is attributed to the modulation of the E-region dynamo electric fields by atmospheric tides, but recent studies indicate that the ionosphere and thermosphere can be directly modulated by the penetration of atmospheric tides into the F-region height.

The temporal evolution of the large equatorial plasma depletions observed during the 29--30 October 2003 storm

This study investigates the temporal evolution of the large plasma depletions observed by ROCSAT-1 and DMSP near 295°E during the 29–30 October 2003 storm. The presence of a penetration electric field around the detection time of the large plasma depletions is supported by the observation of high upward ion drift velocity and formation of an intense equatorial ionization anomaly in the American sector. However, these ionospheric disturbances occur in broad longitude regions; a short-range polarization electric field may adequately explain the creation of the large plasma depletions. The penetration electric field may trigger the Rayleigh–Taylor instability and produce abnormally large plasma depletions during the storm. The TIMED/GUVI and CHAMP observations provide an insight for the evolution of the large depletions several hours after their formation. The large depletions appear as arch-shaped emission depletions in the TIMED/GUVI image and as symmetric depletions paired in the magnetic north and south in the CHAMP observation. These characteristics can be explained by the “plasma depletion shell” phenomenon (Kil et al., 2009) produced by the westward shear flow of the ionosphere during the storm.
