[Toshi Nishimura]

Dear colleagues,

We solicit abstract submissions to the EGU session ST2.6: Multiscale Solar
Wind-Magnetosphere-Ionosphere Interactions: Insights from Observations and
Simulations. The abstract submission deadline is Wednesday, 15 January
2025, at 13:00 CET.

Session Abstract
The solar wind interacts with Earth's magnetosphere-ionosphere system,
driving processes at kinetic, fluid, and global scales. Understanding these
multiscale processes is crucial for a comprehensive grasp of
solar-wind-magnetosphere interactions. This session focuses on studies
using observational data and simulations to explore these interactions
across various scales. At the global scale, we examine characteristics of
geomagnetic storms and substorms as system responses to solar wind
conditions. At the intermediate scale, we investigate phenomena such as
convective flows, convective electric fields, electric current systems,
Kelvin-Helmholtz (KH) instability in boundary layers, flux transfer events,
high-speed jets, ULF waves, and auroral arcs. These phenomena are explored
as consequences of various solar wind drivers and cross-region coupling,
providing insights into the physical links within global processes. At the
kinetic scale, we study kinetic processes and plasma waves to gain insights
into energy dissipation mechanisms. We invite contributions that aim to
elucidate multiscale dynamic processes governing energy transfer, particle
acceleration, energy dissipation, and magnetosphere-ionosphere
disturbances. By integrating data from space missions, ground-based
observatories, and advanced numerical models, our approach will deepen the
understanding of the magnetosphere-ionosphere system's responses to the
solar wind, enhancing our ability to predict space weather.
