The effect of magnetic substorms on near-ground atmospheric current [PDF]
Annales Geophysicae, 2000 Ionosphere-magnetosphere disturbances at high latitudes, e.g. magnetic substorms, are accompanied by energetic particle precipitation and strong variations of the ionospheric electric fields and currents.

Polar Mesospheric Summer Echo Characteristics in Magnetic Local Time and Height Profiles
Journal of Astronomy and Space Sciences, 2023 We conducted a statistical study of polar mesospheric summer echoes (PMSEs) in relation to magnetic local time (MLT), considering the geomagnetic conditions using the K-index (or K).

Are Dawn Storms Jupiter's Auroral Substorms?
AGU Advances, 2021 Dawn storms are among the brightest events in the Jovian aurorae. Up to now, they had only been observed from Earth‐based observatories, only showing the Sun‐facing side of the planet. Here, we show for the first time global views of the phenomenon, from

Space Weather: From solar origins to risks and hazards evolving in time
Frontiers in Astronomy and Space Sciences, 2022 Space Weather is the portion of space physics that has a direct effect on humankind. Space Weather is an old branch of space physics that originates back to 1808 with the publication of a paper by the great naturalist Alexander von Humboldt (Von Humboldt,

Electron Energization Signatures in Traveling Kinetic Alfvén Waves at Storm Time Injection Fronts
Geophysical Research Letters, 2022 The properties of traveling kinetic Alfvén waves (KAWs) and their role in energizing electrons in the inner magnetosphere during a geomagnetic storm are examined using measurements from the Van Allen Probes and Gyrofluid‐Kinetic Electron (GKE) model ...

Lessons from a career in space physics
Frontiers in Astronomy and Space Sciences, 2022 Frameworks for describing magnetospheric substorms are as good as the data on which they are based. While disturbances in the ionosphere are well described by existing data bases, the plasma and field data acquired by satellites in the magnetosphere are ...

Toward the Reconstruction of Substorm‐Related Dynamical Pattern of the Radiowave Auroral Absorption
Space Weather, 2020 In addition to existing empirical models describing the average distributions of energetic electron precipitation into the auroral ionosphere at different activity levels, we develop and test a semiempirical approach to construct dynamical models ...
