Magnetic fields and electric currents around the dayside magnetopause as inferred from data-constrained modeling

Frontiers in Astronomy and Space Sciences
Based on a new mathematical framework and large multi-year multi-mission data sets, we reconstruct electric currents and magnetic fields around the dayside magnetopause and their dependence on the incoming solar wind, IMF, and geodipole tilt.

Artificial Neural Network Model of High‐Latitude Ionospheric Electric Potential: Hemispheric and Equinoctial Asymmetries

Earth and Space Science, Volume 12, Issue 10, October 2025.
Abstract The high‐latitude ionospheric electric field plays a key role in ionospheric plasma dynamics and energetics. Various ground‐ and satellite‐based observations have been utilized to develop empirical models of the convection electric field. Empirical modeling typically relies on statistical regression techniques, where predefined functions are ...

Mini-magnetospheres and Moon-magnetosphere interactions: Overview Moon-magnetosphere Interactions

, 2019
"Moon-magnetosphere interaction" stands for the interaction of magnetospheric plasma with an orbiting moon. Observations and modeling of moon-magnetosphere interaction is a highly interesting area of space physics because it helps to better understand the basic physics of plasma flows in the universe and it provides geophysical information about the ...

Multiple‐Event Study of Substorm Electric Field Penetration Into Middle Latitudes Based on Simultaneous Observation of 630‐nm Airglow Enhancements at Three Stations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract It is known that convection electric fields develop in the polar region associated with substorm onset, and a westward electric field penetrates to lower latitudes on the night side. Two‐dimensional observations of 630‐nm airglow enhancements associated with the westward electric field can be conducted using all‐sky cameras at middle latitudes.

Exploring Localized Geomagnetic Disturbances in Global MHD: Physics and Numerics

Space Weather
One of the prominent effects of space weather is the formation of rapid geomagnetic field variations on Earth's surface driven by the magnetosphere‐ionosphere system.

Daytime Thermospheric Wind Transients and Circulation in May 2021

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Changes in the thermospheric wind originating in storm‐time transients in high‐latitude Joule heating and ion circulation are effective in modifying conditions throughout Earth's upper atmosphere and ionosphere. Among the effects these drivers can produce are large‐scale gravity waves (GWs), characterized by significant wind transients that ...

Scaling of Ion Outflow Speed and Ion Bulk Heating in Lobe Reconnection and Their Relations to Shear Flow

Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.
Abstract Magnetic reconnection at the high‐latitude magnetopause is accompanied by velocity shear due to the tailward flow of the magnetosheath. This study investigates 24 high‐latitude magnetopause reconnection events observed by the Cluster satellites and examines how ion outflow speed and ion bulk heating depend on the upstream Alfvénic parameters ...
