▪ Abstract Impulsive reconnection dynamics is characterized not only by fast growth but also
by a sudden change in the time derivative of the growth rate. I review recent developments …

Auroral substorms are often associated with optical ray or bead structures during initial
brightening (substorm auroral onset waves). Occurrence probabilities and properties of …

We present observations which provide strong support for a substorm expansion phase
onset scenario in which a localized inner magnetospheric instability developed first and was …

In this work, we analyze the ballooning stability of the near-Earth plasma sheet prior to the
initial expansion onset of the 23 March 2007 THEMIS substorm event. Using solar wind data …

This paper deals with ideal‐MHD stability of equilibrium configurations modeling the plasma
sheet of the Earth's magnetotail. The approach exploits the fact that in the absence of a cross …

Two‐dimensional initial value MHD simulations of the linear ideal MHD ballooning instability
in the near‐Earth magnetotail are presented. The configuration of the magnetotail is …

This paper investigates the conditions of the ballooning instability of the coupled Alfvén and
slow magnetoacoustic modes in the dipole model of Earth's magnetosphere taking into …

The westward propagation of wave disturbances associated with current disruption is
observed in the near‐Earth plasma sheet by the Wind satellite. By analyzing the time delay …

We report for the first time the intrinsically three-dimensional (3D) geometry of the magnetic
reconnection process induced by ballooning instability in a generalized Harris sheet. The …

The magnetohydrodynamic (MHD) plasma model, as modified by the Hall effect, is given a
Hamiltonian formulation and its stability properties are studied. It is found that, in most cases …
