| 7 | Interaction between Equatorial Plasma Bubbles and a Medium-Scale Traveling Ionospheric Disturbance,observed by OI 630 nm airglow imaging at Bom Jesus de Lapa,Brazil显示文摘OI 630.0 nm airglow observations,from a new observatory at Bom Jesus de Lapa,were used to study the interaction between EPBs(Equatorial Plasma Bubbles)and the MSTID(Medium-Scale Traveling Ionospheric Disturbance)over the Northeast region in Brazil.On the night of September 16 to 17,2020,an EPB was observed propagating eastward,in an apparent fossil stage,until it interacted with a dark band electrified MSTID(e MSTID).After the interaction,four EPBs merged,followed by an abrupt southward development and bifurcations.Analysis of the data suggests that an eastward polarization electric field,induced by the dark band e MSTID,forced the EPB into an upward drift,growing latitudinally along the magnetic field lines and then bifurcating. | Cristiano Max Wrasse Cosme Alexandre Oliveira Barros Figueiredo Diego Barros Hisao Takahashi Alexander JoséCarrasco Luiz Fillip Rodrigues Vital Láysa Cristina Araujo Resende Fábio Egito Geângelo de Matos Rosa Antonio Hélder Rodrigues Sampaio | 2021 | Earth and Planetary Physics2021，5，5： | 0 |
