Midlatitude postsunset plasma bubbles observed over Europe during intense storms in April 2000 and 2001 [PDF]
Plasma bubbles are prevalent features of the equatorial/low-latitude ionosphere which are seldom observed at middle and high latitudes. Understanding the influence of geomagnetic storms on plasma bubbles' migration to higher latitudes is an important ...

Vortex bubble formation in pair plasmas [PDF]
It is shown that delocalized vortex solitons in relativistic pair plasmas with small temperature asymmetries can be unstable for intermediate intensities of the background electromagnetic field. Instability leads to the generation of ever-expanding cavitating bubbles in which the electromagnetic fields are zero.

Shrinking equatorial plasma bubbles [PDF]
AbstractThe formation of equatorial plasma bubbles (EPBs) associated with spread F irregularities are fairly common phenomenon in the postsunset equatorial ionosphere. These bubbles grow as a result of eastward polarization electric field resulting in upward E × B drift over the dip equator.

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 ...

Ionospheric Turbulence and the Equatorial Plasma Density Irregularities: Scaling Features and RODI
In the framework of space weather, the understanding of the physical mechanisms responsible for the generation of ionospheric irregularities is particularly relevant for their effects on global positioning and communication systems.

This study, for the first time, reports the geomagnetically conjugate structure of a plasma bubble extending to the mid-latitudes and the asymmetrical structure of the decay of the plasma bubble during a geomagnetic storm.

Zonal velocity of the equatorial plasma bubbles over Kolhapur, India [PDF]
This paper presents the observations of zonal drift velocities of equatorial ionospheric plasma bubbles and their comparison with model values. These velocities are determined by nightglow OI 630.0 nm images.

Semimonthly oscillation observed in the start times of equatorial plasma bubbles [PDF]
Using airglow data from an all-sky imager deployed at São João do Cariri (7.4∘ S, 36.5∘ W), the start times of equatorial plasma bubbles was studied in order to investigate the day-to-day variability of this phenomenon.

The occurrence of plasma irregularities and ionospheric scintillation over the Caribbean region have been reported in previous studies, but a better understanding of the source and conditions leading to these events is still needed.

The Quest for the Most Spherical Bubble [PDF]
We describe a recently realized experiment producing the most spherical cavitation bubbles today. The bubbles grow inside a liquid from a point-plasma generated by a nanosecond laser pulse. Unlike in previous studies, the laser is focussed by a parabolic
