This study documents decadal-scale changes in the Holton and Tan (HT) relationship, i.e., the influence of the lower stratospheric equatorial quasi-biennial oscillation (QBO) on the northern hemisphere (NH) extratropical circulation. […]
This study investigates if the descent of odd nitrogen, generated in the thermosphere and the upper mesosphere by energetic particle precipitation (EPP-NOx), has a detectable impact on stratospheric wind and […]
During the Halloween Storm period (October–November 2003), a new Van Allen belt electron population was powerfully accelerated. The inner belt of electrons formed in this process decayed over a period […]
The tilt and offset of the Earth’s magnetic field can significantly affect the longitudinal and seasonal distribution of electron density in the plasmasphere. Here we show that for the solar […]
The excitation of nightside whistler mode chorus emissions in the low-density region outside the plasmapause is investigated during an injection of plasma sheet electrons into the inner magnetosphere. CRRES data […]
In this paper, we focus on the modeling of radial transport in the Earth’s outer radiation belt. A historical overview of the first observations of the radiation belts is presented, […]
Fast magnetosonic waves can lead to the local acceleration of electrons from ∼10 keV up to a few MeV on a timescale of 1–2 d and may play an important […]
Nonadiabatic loss processes of radiation belt energetic electrons include precipitation loss to the atmosphere due to pitch-angle scattering by various magnetospheric plasma wave modes. Here we consider electron precipitation loss […]
The principal loss mechanism for electrons from the inner radiation belt (1.2 < L < 2.0) and slot region (2.0 < L < 3.0) is atmospheric precipitation driven by several […]
Plasmaspheric hiss1 is a type of electromagnetic wave found ubiquitously in the dense plasma region that encircles the Earth, known as the plasmasphere2. This important wave is known to remove3, […]
Energetic electrons (≥50 keV) are injected into the slot region (2 < L < 4) between the inner and outer radiation belts during the early recovery phase of geomagnetic storms. […]
Wave-particle interactions lead to the loss of relativistic electrons from the outer radiation belt on timescales ranging from hours to weeks. For a fixed value of chorus wave amplitudes pitch-angle […]
