| description | 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 irregularities in the equatorial F-region. Such bubbles are seen as plasma depletion holes (in situ satellite
observations), vertical plumes (radar observations), and emission-depletion bands elongated in the north-south direction
(optical observations). However, no technique can observe the whole three-dimensional structure of a bubble. Various
aspects of bubbles identified using different techniques indicate that a bubble has a “shell” structure. This paper reviews
the development of the concepts of “bubble” and “shell” in this context. |
