Equatorial Plasma Bubble (EPB) to atmosphere relationship found from day-to-day variation of GPS scintillation and GAIA assimilation data

摘要

Equatorial plasma bubble (EPB) is one of intense ionospheric phenomena that occur in the low-latitude and equatorial ionosphere. EPB is the phenomenon in which depletion of ionospheric plasma at the bottom side F-region becomes unstable, and rapidly grows and upwells to an altitude of up to 1000 km. The growth mechanism of EPBs is understood via the Rayleigh-Taylor instability. However, studies of day-to-day variability in EPB activity are few.
