Short summary
Short summary
It has been shown that guide fields substantially modify the structure of reconnection layers. In this paper, we studied the electric field structures in magnetic reconnection under different initial guide fields (Bg). Once the amplitude of a guide field exceeds 0.3 times the asymptotic magnetic field B0, the traditional bipolar Hall electric field is clearly replaced by a tripolar electric field, which consists of a newly emerged electric field and the bipolar Hall electric field.

Electron energization is an outstanding issue in magnetic reconnection, which is a hot topic in plasma physics and astrophysics. Four different structures have been proposed for electron energization during reconnection. We find that there is no specific sequence of electron energization through the four structures; there is no specific order of electron acceleration efficiency among the four structures, and electron energization occurs in a wide region around X-line.

Short summary
From the statistical analysis of potential plasmaspheric plume, we find that there is almost no correlation between plume width and the level of geomagnetic storm intensity. However, for plumes in the recovery phase after improved sifting, there is a negative correlation between the plume width and absolute value of minimum Dst during the storm. We suggest that the plasmaspheric particles may escape quickly during intense storms, causing plume to be relatively narrow during the recovery phase.

Short summary
The plasmaspheric plume is an important region of detached plasma elements and provides an effective coupling channel of energy/mass between the inner magnetospheric plasmasphere and outer magnetosphere. In this study, using Van Allen Probe data, we present a statistical result of plasmaspheric plumes in the inner magnetosphere, which implies that the plumes tend to occur during the recovery phase of geomagnetic storms, and the occurrence rate is larger during stronger geomagnetic activity.

Short summary
We report an event where hiss wave intensity decreased, associated with the enhanced convection and a substorm. We suggest that the enhanced magnetospheric electric field causes the outward and sunward motion of energetic electrons. This leads to the decrease of energetic electron fluxes on the duskside, which provide free energy for hiss amplification. The study reveals the important role of magnetospheric electric field in the variation of the energetic electron flux and hiss wave intensity.

Short summary
Oxygen ions are an important element in the mass and energy transport in the magnetospheric dynamic process during intense substorms (AE > 500 nT). We did this work to better understand the O+ at the dusk flank magnetopause varying with solar wind conditions and AE index during intense substorms. The results show the O+ abundance at the duskside magnetopause has a corresponding relation to that in the duskside near-Earth plasma sheet.

The Kelvin–Helmholtz waves are believed to be an effective way to transport solar wind mass and energy into Earth's magnetosphere. In this study, we show that the ion-scale flux rope generated at the trailing edge of Kelvin–Helmholtz waves by multiple X-line reconnection could be directly related to this transfer process. The lower hybrid drift waves detected at the edges of the flux rope can also contribute to this process and then affect the revolution of the flux rope.

With observations of the Cluster spacecraft, we report in situ evidence of energetic ions scattered into the loss cone during the inbound pass from the plasma sheet into the plasmasphere. Our results suggest that energetic ions scattering into the loss cone in the central plasma sheet and the outer boundary of the plasmaspheric plume are attributed to the field line curvature scattering mechanism and EMIC wave scattering mechanism, respectively.

The solar wind magnetic field drapes around the active nucleus of comet 67P/CG, creating a magnetosphere. The solar wind density increases and with that the pressure, which compresses the magnetosphere, increasing the magnetic field strength near Rosetta. The higher solar wind density also creates more ionization through collisions with the gas from the comet. The new ions are picked-up by the magnetic field and generate mirror-mode waves, creating low-field high-density "bottles" near 67P/CG.

We use THEMIS large data set of dipolarization front events to build a 2-D pressure distribution in XZ plane, and thus derive the current system around the dipolarization front. Our results show that a banana current loop is formed around the dipolarization front. This current is also suggested to be the reason for the magnetic dip observed ahead of the dipolarization front. In addition, the current density is too small to contribute a substorm current wedge.

We present a first report on magnetic field measurements made in the coma of comet 67P/C-G in its low-activity state. The plasma environment is dominated by quasi-coherent, large-amplitude, compressional magnetic field oscillations around 40mHz, differing from the observations at strongly active comets where waves at the cometary ion gyro-frequencies are the main feature. We propose a cross-field current instability associated with the newborn cometary ions as a possible source mechanism.

Short summary
Magnetic reconnection is one of the main processes for energy conversion and plasma transport in space plasma physics, associated with plasma entry into the magnetosphere of Earth and Earth’s substorm cycle. Global modelling of these plasma processes enables us to understand the magnetospheric system in detail. However, finding sites of active reconnection from large simulation datasets can be challenging, and this paper develops tools to find magnetic topologies related to reconnection.
