One of the definitions of space weather describes it as the time-varying space environment
that may be hazardous to technological systems in space and/or on the ground and/or …

We discuss results of a superposed epoch analysis of dipolarization fronts, rapid (δt< 30 s),
high‐amplitude (δBz> 10 nT) increases in the northward magnetic field component …

Energetic particle injections are critical for supplying particles and energy to the inner
magnetosphere. Recent case studies have demonstrated a good correlation between …

Dipolarization fronts (DFs), characterized by a strong and steep increase of the tail magnetic
field component Bz normal to the neutral plane and preceded by a much less negative dip of …

We study energetic electron injections by using an analytical model that self‐consistently
describes electric and magnetic field perturbations of a transient, localized dipolarizing flux …

Motivated by recent observations of intense electric fields and elevated energetic particle
fluxes within flow bursts beyond geosynchronous altitude (Runov et al., 2009, 2011), we …

In this paper, we investigate the role of plasma sheet bubbles in the ion flux variations at
geosynchronous orbit during substorm injections by using the Rice Convection Model with …

Using an analytical model of multiple dipolarizing flux bundles (DFBs) embedded in
earthward traveling bursty bulk flows, we demonstrate how equatorially mirroring electrons …

Substorms generally inject tens to hundreds of keV electrons, but intense substorm electric
fields have been shown to inject MeV electrons as well. An intriguing question is whether …

Taking advantage of multipoint observations from a Cluster‐like Time History of Events and
Macroscale Interactions during Substorms (THEMIS) probe configuration repeated in three …
