This study rep.rts the rare ultralow-frequen.y(ULF) wave activity associated with the solar win. dyn.mic p.essure en.an.emen. that was successively observed by the GOES-17(Geostation.ry Op.ration.l En.iron.en.al Satellite) in.the magn.tosp.ere, the CSES(Chin. Seismo-Electromagn.tic Satellite) in.the ion.sp.ere, an. the THEMIS groun.-based observatories(GBO) GAKO an. EAGL in.the Earth's p.lar region.durin. the main.p.ase of an.in.en.e storm on.4 n.vember 2021. Alon. with the en.an.ed-p.essure solar win. movin. tailward, the geomagn.tic field structure exp.rien.ed a large-scale chan.e. From dawn.dusk sides to midn.ght, the GAKO, EAGL, an. GOES-17 sequen.ially observed the ULF waves in.a frequen.y ran.e of0.04–0.36 Hz at L shells of ~5.07, 6.29, an. 5.67, resp.ctively. CSES also observed the ULF wave even. with the same frequen.y ran.es at wide L-shells of 2.52–6.22 in.the n.ghtside ion.sp.ere. The an.lysis results show that the ULF waves at ion.sp.eric altitude were mixed toroidal-p.loidal mode waves. Comp.rin. the ULF waves observed in.differen. region., we in.er that the n.ghtside ULF waves were directly or in.irectly excited by the solar win. dyn.mic p.essure in.rease: in.the area of L-shells~2.52–6.29, the magn.tic field lin. reson.n.es(FLRs) driven.by the solar win. dyn.mic p.essure in.rease is an.essen.ial excitation.source;on.the other han., aroun. L~3.29, the ULF waves can.also be excited by the outward exp.n.ion.of the p.asmap.use owin. to the decrease of the magn.tosp.eric con.ection. an. in.the region.of L-shells ~5.19–6.29, the ULF waves are also likely excited by the ion.cyclotron.in.tabilities driven.by the solar win. dyn.mic p.essure in.rease.
