Asymmetric distributions of auroral kilometric radiation in Earth's northern and southern hemispheres observed by the Arase satellite

F Xiao, J Tang, S Zhang, Q Zhou, S Liu… - Geophysical …, 2022 - Wiley Online Library
Auroral kilometric radiation (AKR) is generated at high latitudes and can propagate down to
low latitudes. Due to the lack of direct observations, the characteristics of AKR in the middle …

Substorm simulation: Formation of westward traveling surge

Y Ebihara, T Tanaka - Journal of Geophysical Research: Space …, 2015 - Wiley Online Library
Auroral substorm expansion is characterized by initial brightening of aurora, followed by a
bulge expanding in all directions, and a westward traveling surge (WTS). On the basis of the …

Simulation study of near-Earth space disturbances: 2. Auroral substorms

Y Ebihara - Progress in Earth and Planetary Science, 2019 - Springer
A substorm is a transient phenomenon that lasts for only 1–2 h. One significant manifestation
of the substorm is a sudden brightening of the aurora on the nightside. Simultaneously, the …

Evolution of IMF By Induced Asymmetries: The Role of Tail Reconnection

A Ohma, N Østgaard, KM Laundal… - Journal of …, 2021 - Wiley Online Library
North‐south asymmetries arise in the magnetosphere‐ionosphere system when a significant
east‐west (By) component is present in the interplanetary magnetic field (IMF). During such …

Time‐dependence of dawn‐dusk asymmetries in the terrestrial ionospheric convection pattern

A Grocott - Dawn‐dusk asymmetries in planetary plasma …, 2017 - Wiley Online Library
In this chapter we consider the nature and origin of dawn‐dusk asymmetries in the
ionospheric convection pattern. We focus on asymmetries that are introduced via solar wind …

Evolution of IMF B y induced asymmetries during substorms: Superposed epoch analysis at geosynchronous orbit

A Ohma, KM Laundal, JP Reistad… - Frontiers in Astronomy …, 2022 - frontiersin.org
The B y component of the magnetic field inside the magnetosphere is positively correlated
with the B y component of the Interplanetary Magnetic Field (IMF). This leads to asymmetries …

Interhemispheric magnetic conjugacy

NY Ganushkina, MV Kubyshkina… - Journal of …, 2013 - Wiley Online Library
The concept of the inter‐hemispheric magnetic conjugacy was investigated by comparing
the conjugate points in the northern and southern hemispheres using the Tsyganenko T02 …

Asymmetric development of auroral surges in the northern and southern hemispheres

HA Uchida, R Kataoka, A Kadokura… - Geophysical …, 2020 - Wiley Online Library
Simultaneous eastward and westward traveling surges were observed at Tjörnes, Iceland,
and Syowa station, Antarctica, respectively. Several remarkable differences were …

Simulation of substorm‐time acceleration of oxygen ions on azimuthally directed magnetic field lines in the near‐Earth plasma sheet

Y Nakayama, Y Ebihara… - Journal of Geophysical …, 2014 - Wiley Online Library
Acceleration of energetic ions is one of the drastic and common phenomena in the near‐
Earth plasma sheet during the expansion phase of substorms. When a magnetic field line is …
