A Peculiar Discontinuous Ionospheric Latitudinal Variation Over the East Asia Region During the Recovery Phase of the November 2003 Super Magnetic Storm: A Hint From May 2024 Superstorm
Abstract In this study, we analyze a discontinuous negative storm evolution process in the ionosphere over the East Asian region during the recovery phase of the geomagnetic storms on 20 and 21 November 2003, using data from the Global Ultraviolet Imager (GUVI) for [O] and [N2] column density ratio...

| description | Abstract In this study, we analyze a discontinuous negative storm evolution process in the ionosphere over the East Asian region during the recovery phase of the geomagnetic storms on 20 and 21 November 2003, using data from the Global Ultraviolet Imager (GUVI) for [O] and [N2] column density ratio (Σ[O]/[N2]), Total Electron Content (TEC), as well as ionospheric parameters, namely, the ionospheric peak height (hmF2) and peak electron density (NmF2), supplemented by Thermosphere Ionosphere Electrodynamics General Circulation Model (TIEGCM) simulations. The event lasted 3–4 hr and may represent the first simultaneous observation of vortex‐like structures in both the thermosphere and ionosphere since Solar Cycle 23. Our research findings suggest that this structure is most probably related to the vortex‐like structure of thermospheric composition caused by thermospheric winds blowing from the Southern Hemisphere under the influence of pressure gradient force and Coriolis force. |
