Analysis of the seasonal variations of equatorial plasma bubble occurrence observed from Haleakala, Hawaii [PDF]

Annales Geophysicae, 2004
Over 300 nights of airglow and GPS scintillation data collected between January 2002 and August 2003 (a period near solar maximum) from the Haleakala Volcano, Hawaii are analyzed to obtain the seasonal trends for the occurrence of equatorial plasma ...

Equatorial Plasma Bubbles: A Review

Atmosphere, 2022
The equatorial plasma bubble (EPB) phenomenon is an important component of space weather as the ionospheric irregularities that develop within EPBs can have major detrimental effects on the operation of satellite-based communication and navigation ...

Equatorial plasma bubble seeding by MSTIDs in the ionosphere

Progress in Earth and Planetary Science, 2018
Occurrences of equatorial plasma bubbles (EPBs) and medium-scale traveling ionospheric disturbances (MSTIDs) were studied using GPS satellite data-based total electron content mapping, ionograms, and 630 nm all-sky airglow images observed over the South ...

The study of equatorial plasma bubble during January to April 2012 over Kolhapur (India) [PDF]

Annals of Geophysics, 2016
Over 53 nights of all sky airglow imager data collected during January-April 2012 from the low latitude station Kolhapur (16.68°N, 74.26°E; 10.6°N dip latitude) have been analyzed to study the F-region dynamics through the imaging of OI 630 nm emission ...

Effects of the postsunset vertical plasma drift on the generation of equatorial spread F

Progress in Earth and Planetary Science, 2018
Equatorial spread F (ESF) irregularities are caused by plasma instability processes in the equatorial ionosphere and especially related to plasma bubble phenomena in the topside F region.

Cluster and Double Star multipoint observations of a plasma bubble [PDF]

, 2009
Depleted flux tubes, or plasma bubbles, are one possible explanation of bursty bulk flows, which are transient high speed flows thought to be responsible for a large proportion of flux transport in the magnetotail. Here we report observations of one such

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

J Synchrotron Radiat
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

The impact of gravity waves rising from convection in the lower atmosphere on the generation and nonlinear evolution of equatorial bubble [PDF]

Annales Geophysicae, 2009
The nonlinear evolution of equatorial F-region plasma bubbles under varying ambient ionospheric conditions and gravity wave seeding perturbations in the bottomside F-layer is studied.

Occurrence characteristics of branching structures in equatorial plasma bubbles: a statistical study based on all-sky imagers in China

Earth and Planetary Physics, 2021
Branching structure (BS) is a very important phenomenon in the evolution of equatorial plasma bubbles (EPBs), the mechanism of which is widely studied from observation and from simulation.
