Title

Modeling the development of an equatorial plasma bubble during a midnight temperature maximum with SAMI3/WACCM-X

Abstract

We report results from a self-consistent global simulation model in which a large-scale equatorial plasma bubble (EPB) forms during a midnight temperature maximum (MTM). The global model comprises the ionospheric code SAMI3 and the atmosphere/thermosphere code WACCM-X. We consider solar minimum conditions for the month of August. We show that an EPB forms during an MTM in the Pacific sector and is caused by equatorward neutral wind flows. Although this is consistent with the theoretical result that a meridional neutral wind (V) with a negative gradient ( partial differential V/ partial differential theta; 0) is a destabilizing influence [Huba Krall, 2013, ] (where a northward meridional neutral wind V is positive and theta; is the latitude and increases in the northward direction), we find that the primary cause of the EPB is the large decrease in the Pedersen conductance caused by the equatorward winds.
