Generation of equatorial plasma bubble after the 2022 Tonga volcanic eruption. [PDF]
Sci Rep, 2023 Equatorial plasma bubbles are a phenomenon of plasma density depletion with small-scale density irregularities, normally observed in the equatorial ionosphere.

The Morphology of Equatorial Plasma Bubbles - A Review [PDF]
Journal of Astronomy and Space Sciences, 2015 Plasma bubbles that occur in the equatorial F-region make up one of the most distinguishing phenomena in the ionosphere. Bubbles represent plasma depletions with respect to the background ionosphere, and are the major source of electron density ...

Frontiers in Astronomy and Space Sciences, 2023 A wide variety of small-amplitude waves widely exist in the ionosphere and have significant effects on the evolution of equatorial plasma bubbles. In this paper, we simulated equatorial plasma bubbles (EPB) seeded by vertical neutral wind perturbations ...

Effect of magnetic activity on plasma bubbles over equatorial and low-latitude regions in East Asia [PDF]
Annales Geophysicae, 2009 The dependence of plasma bubble occurrence in the eveningside ionosphere, with magnetic activity during the period years 2001–2004, is studied here based on the TEC observations gathered by ground-based GPS receivers which are located in the ...

Concurrent study of bottomside spread F and plasma bubble events in the equatorial ionosphere during solar maximum using digisonde and ROCSAT-1 [PDF]
Annales Geophysicae, 2005 Data from the Jicamarca digisonde and the ROCSAT-1 satellite are employed to study the equatorial ionosphere on the west side of South America during April 1999-March 2000 for the concurrent bottomside spread F (BSSF) and plasma bubble events.

Earth, Planets and Space, 2023 Ionospheric structure is characterized by the space–time variation of electron density. However, our understanding of the physical processes that initiate and sustain intermediate-scale structure development does not relate directly to statistical ...

Filamentary Alfvénic structures excited at the edges of equatorial plasma bubbles [PDF]
Annales Geophysicae, 2007 Recent observations performed by the French DEMETER satellite at altitudes of about 710 km suggest that the generation of equatorial plasma bubbles correlates with the presence of filamentary structures of field aligned currents carried by Alfvén ...

Relationship between ionospheric plasma bubble occurrence and lightning strikes over the Amazon region [PDF]
Annales Geophysicae, 2018 The vertical coupling between the troposphere and the ionosphere presents some remarkable features. Under intense tropospheric convection, gravity waves may be generated, and once they reach the ionosphere, these waves may seed instabilities and ...
