Morphology of equatorial plasma bubbles

Journal of Geophysical Research: Space Physics, 1997
Some occurrence characteristics of plasma bubbles based on data from the ion drift meter aboard the Atmosphere Explorer E satellite are presented. Of 5200 bubbles detected between 250 and 475 km altitude, 65% had ion density depletions of less than 1 order of magnitude below the ambient ion density, and the occurrence frequency decreased with ...

Downdrafting plasma flow in equatorial bubbles

Journal of Geophysical Research: Space Physics, 1994
The electric field experiment carried aboard the San Marco D equatorial ionospheric satellite regularly measured updrafting in plasma depletion channels or “equatorial bubbles” which form on the bottomside of the nightside equatorial F region. We report here observations of downdrafting vertical plasma velocities inside such depletion regions in the ...

Transequatorial VHF propagation through equatorial plasma bubbles

Radio Science, 1979
The support by the nighttime equatorial ionosphere of radio wave propagation at frequencies exceeding 50 MHz is explained in terms of guiding along field‐aligned tubes of depleted ionization resulting from the postsunset creation of equatorial plasma bubbles.

Equatorial Plasma Bubbles: Zonal Thermosphere Wind Influence

Geomagnetism and Aeronomy, 2023
There are a number of the theoretical studies pointing to the key role of the zonal thermosphere winds in the equatorial plasma bubble (EPB) generation and evolution. However, there are insufficient observational data to confirm the relationship between these phenomena.

Occurrence of equatorial plasma bubbles over Kolhapur

Advances in Space Research, 2014
Abstract This paper reports the nightglow observations of OI 630.0 nm emissions, made by using all sky imager operating at low latitude station Kolhapur (16.8°N, 74.2°E and dip lat. 10.6°N) during high sunspot number years of 24th solar cycle. The images are analyzed to study the nocturnal, seasonal and solar activity dependence occurrence of plasma ...

Equatorial F-Region Plasma Bubbles Studies

5th International Congress of the Brazilian Geophysical Society, 1997
Equatorial ionospheric plasma bubbles associated with equatorial range-type spread F, are regions where the plasma densities are much lower than the ambient plasma density and are aligned along the earth's magnetic field lines . The plasma bubbles can be observed by both the radio wave (e.g. ionosonde, radar, scintillation etc.) and optical techniques (
