Using SAMI3 to self-consistently model MSTIDs
Abstract
Recent optical observations (Miller et al., 2009; Makela et al., 2010) have suggested that electrified, nighttime medium-scale traveling ionospheric disturbances (MSTIDs) can propagate to low latitudes, where they can potentially act as a seed mechanism for the development of equatorial plasma bubbles. Using the SAMI3 model, Krall et al (2011) demonstrated that this was, indeed, a plausible seeding mechanism. However, this initial modeling study used an imposed electric field that was consistent with previous MSTID observations. Here, we develop a self-consistent description of MSTIDs within the SAMI3 framework which can be used to study the propagation of MSTIDs to low latitudes and their potential for seeding EPB development.
