Occurrence of Equatorial Plasma Bubbles during Intense Magnetic Storms [PDF]

International Journal of Geophysics, 2011
An important issue in low-latitude ionospheric space weather is how magnetic storms affect the generation of equatorial plasma bubbles. In this study, we present the measurements of the ion density and velocity in the evening equatorial ionosphere by the

Generation of enigmatic equatorial ionospheric plasma blobs during the 17 March 2015 super geomagnetic storm period over the Indian region [PDF]

Scientific Reports
In general, during geomagnetic storm times, equatorial ionospheric plasma bubbles (equivalently plasma depletions) will be generated due to the effect of prompt penetration of magnetosphere-associated disturbed electric fields to the magnetic equatorial ...

Magnetic Field and Electron Density Scaling Properties in the Equatorial Plasma Bubbles

Remote Sensing, 2022
The ionospheric plasma density irregularities are known to play a role in the propagation of electromagnetic signals and to be one of the most important sources of disturbance for the Global Navigation Satellite System, being responsible for degradation ...

Correlative X‐ray imaging and fluorescence microscopy in hydrated environments [PDF]

Journal of Synchrotron Radiation, Volume 33, Issue 6, Page 1779-1793, November 2026.
We present a combined imaging platform that integrates beamline‐compatible fluorescence microscopy with scanning small‐angle X‐ray scattering to enable sequential multimodal investigations of hydrated cells under near‐native conditions. We apply our method to ordered cytoskeletal structures in different cell types and demonstrate the direct correlation

A review on the numerical simulation of equatorial plasma bubbles toward scintillation evaluation and forecasting

Progress in Earth and Planetary Science, 2017
Equatorial plasma bubbles (EPBs) have been a longstanding and increasingly important subject because they cause severe scintillations in radio waves from Global Navigation Satellite System satellites.

The Impact of Vertical Plasma Motion on the Evolution of Predawn Equatorial Plasma Bubbles on the Dayside

Geophysical Research Letters
This study investigates the impact of vertical ionospheric drift during daytime on the evolution of predawn equatorial plasma bubbles by conducting model simulations using “Sami3 is Another Model of the Ionosphere.” The upward drift of the ionosphere ...

F-Region electron density irregularities during the development of equatorial plasma bubbles [PDF]

Geofísica Internacional, 2000
The height variation of the ionospheric electron density was measured with rocket-borne electron density probes in two campaigns conducted from Alcantara (2.31°S; 35.2°W), Brazil. A Black Brant X sounding rocket was launched on 14 October 1994 at 1955hrs

On the Seeding of Equatorial Plasma Bubbles by Longitudinal Variations in the Meridional Wind

Geophysical Research Letters
We report results from SAMI3/WACCM‐X simulations that small‐scale (∼few 100 km) longitudinal variations in the meridional wind provide seeds to initiate equatorial plasma bubbles (EPBs).

A system science perspective of the drivers of equatorial plasma bubbles

Frontiers in Astronomy and Space Sciences, 2023
The complex drivers of equatorial plasma bubbles and resulting scintillation requires a system science approach spanning the Magnetosphere-Ionosphere-Thermosphere-Mesosphere disciplines.
