Almost 40 years ago the concept of the substorm current wedge was developed to explain
the magnetic signatures observed on the ground and in geosynchronous orbit during …

Dawn–dusk asymmetries are ubiquitous features of the coupled solar-wind–magnetosphere–
ionosphere system. During the last decades, increasing availability of satellite and ground …

We report THEMIS observations of a dipolarization front, a sharp, large‐amplitude increase
in the Z‐component of the magnetic field. The front was detected in the central plasma sheet …

Using Time History of Events and Macroscale Interactions during Substorms observations
from four tail seasons, we study the three‐dimensional structure of the dipolarization front …

In a two‐fluid picture of magnetic reconnection, inflow electrons flow with the magnetic field
line to the diffusion region, whereas inflow ions cannot reach the diffusion region and rest …

Earthward flow bursts associated with small auroral expansions, including pseudobreakups,
and auroral streamers are studied by using Geotail plasma and magnetic field data and …

In particular during the descending phase of the solar cycle, Alfvén waves in the high-speed
solar wind streams are a major form of interplanetary disturbances. The fluctuating …

The occurrence rate of earthward‐propagating dipolarization fronts (DFs) is investigated in
this paper based on the 9 years (2001–2009) of Cluster 1 data. For the first time, we select …

Using the electromagnetic fields of a recent MHD simulation of magnetotail reconnection,
flow bursts and dipolarization, we investigate the acceleration of test particles (protons and …

Using the observations of three satellites of Cluster (C1, C3, and C4) during the periods July
to October 2001 and July to October 2002, we study 209 active time bursty bulk flows …
