Model study of the earth’s ionosphere electric currents system at high latitudes [PDF]
E3S Web of ConferencesThis paper presents a numerical study of the response of high- latitudinal Earth’s ionosphere electric currents system to different magne- tospheric inputs. The ionosphere states were modeled using the Upper At- mosphere Model (UAM).

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Passive microwave radiances near 23.8 GHz constrain lower‐tropospheric water vapor, but this protected window lies adjacent to fifth‐generation (5G) telecommunications spectrum. We quantify how projected terrestrial 5G leakage propagates through county‐scale deployment projections, directional antenna geometry, synthetic contamination of AMSU ...

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Along the flank magnetopause, magnetosheath flow interfaced with the relatively stationary magnetosphere produces strong flow shears, and the Kelvin‐Helmholtz instability (KHI) occurs. When the interplanetary magnetic field (IMF) is southward, anti‐parallel day‐side reconnection and KHI can interact, which may enhance the reconnection rate as ...

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Quantifying energetic electron precipitation is essential for understanding ring current and radiation belt loss, as well as magnetosphere‐ionosphere‐atmosphere coupling. The count rate ratio between the 90° and 0° telescopes (CR90/CR0) on POES/MetOp satellites is a commonly used proxy for precipitation and pitch‐angle diffusion rates (DW ${D ...

Effect of the ring current on preconditioning the magnetosphere for steady magnetospheric convection
Geophysical Research Letters, 2013 Steady magnetospheric convection (SMC) occurs when reconnection rates on the dayside and in the distant tail are balanced. An enhanced ring current could support this, by stabilizing the tail against near‐Earth reconnection and by facilitating the prompt return of magnetic flux to the dayside.

Magnetospheric and Atmospheric Controls of Giant Planet Auroral Currents
, 2018 Planetary atmospheres and their surrounding plasma environments exchange energy and momentum through magnetosphere‐ionosphere‐thermosphere (MIT) coupling. This fundamental process is mediated by the planetary magnetic field, which connects the ionosphere,

ADJUSTMENT OF THE ELECTRIC CHARGE AND CURRENT IN PULSAR MAGNETOSPHERES [PDF]
The Astrophysical Journal, 2009 We present a simple numerical model of the plasma flow within the open field line tube in the pulsar magnetosphere. We study how the plasma screens the rotationally induced electric field and maintains the electric current demanded by the global structure of the magnetosphere. We show that even though bulk of the plasma moves outwards with relativistic

Processes in auroral oval and outer electron radiation belt
Earth, Planets and Space, 2018 We have analyzed the role of auroral processes in the formation of the outer radiation belt, considering that the main part of the auroral oval maps to the outer part of the ring current, instead of the plasma sheet as is commonly postulated.
