Plasmoid-Induced-Reconnection and Fractal Reconnection [PDF]

Earth, Planets and Space, 2000
As a key to undertanding the basic mechanism for fast reconnection in solar flares, plasmoid-induced-reconnection and fractal reconnection are proposed and examined.

Magnetosphere-Ionosphere Coupling: Implications of Non-Equilibrium Conditions

Frontiers in Astronomy and Space Sciences, 2022
The response times of the coupled magnetosphere-ionosphere-thermosphere system are, on average, greater than the autocorrelation timescales of solar wind forcing. This means that the system is rarely, if ever, in equilibrium.

A Review of Studies of Geomagnetic Storms and Auroral/Magnetospheric Substorms Based on the Electric Current Approach

Frontiers in Astronomy and Space Sciences, 2021
The progress of space physics is reviewed from my personal point of view, particularly how I have reached my present understanding of auroral substorms and geomagnetic storms from the time of the earliest days of space physics.

Effects from dayside magnetosphere to distant tail unleashed by a bifurcated, non-reconnecting interplanetary current sheet

Frontiers in Physics, 2022
Global magnetospheric effects resulting from the passage at Earth of large-scale structures have been well studied. The effects of common and short-term features, such as discontinuities and current sheets (CSs), have not been studied in the same depth ...

Further investigation of the effect of upstream solar-wind fluctuations on solar-wind/magnetosphere coupling: Is the effect real?

Frontiers in Astronomy and Space Sciences, 2023
There is a general consensus that fluctuations in the solar wind magnetic field and/or the Alfvenicity of the solar wind drive a solar wind-magnetosphere interaction.

Reconnection in a pinch

Frontiers in Astronomy and Space Sciences, 2023
A recently published analysis of current sheets has updated the classic Harris 1D static solution by considering multiple classes of charged particle trajectories in a generalized and dynamic current sheet. It uses a 1D PIC simulation to describe dynamic

TR Jets above Magnetic X-Type Null Points [PDF]

Iranian Journal of Astronomy and Astrophysics, 2023
Various chromosphere and transition region jet-like structures abound playing an essential role in the dynamics and evolution therein. Tentatively identifying the wave characteristics and oscillatory behavior in the outer solar atmosphere helps to ...

Modeling the Effect of Enhanced Lateral Connectivity on Nutrient Retention Capacity in Large River Floodplains: How Much Connected Floodplain Do We Need?

Frontiers in Environmental Science, 2020
Floodplains have been degraded in Central Europe for centuries, resulting in less dynamic and less diverse ecosystems than in the past. They provide essential ecosystem services like nutrient retention to improve overall water quality and thus fulfill ...

Topside Reconnection

Frontiers in Physics, 2020
It is proposed that reconnection would be a main mechanism governing the plasma processes on auroral time scales in the topside ionosphere/high-latitude magnetosphere transition.

Waves Generated by Electron Beam in a Crater-Shaped Flux Rope

Frontiers in Physics, 2021
Understanding the nature and characteristics of high-frequency waves inside a flux rope may be important as the wave-particle interaction is important for charged-particle energization and the ensuing dissipation process. We analyze waves generated by an
