The uniqueness of polar regions for conducting geospace research has been acknowledged for decades. This is because instrumentation located at high-latitudes allows access to a natural laboratory for studying the Earth’s atmosphere, its space environment, and solar-generated interplanetary structures. Many fundamental aspects of the plasma dynamics in the polar regions remain unsolved, including the origin of interhemispheric asymmetries, representing a barrier to understanding the thermosphere-ionosphere-magnetosphere system. These dynamics impact a number of important phenomena such as (and not only) auroral patterns, induced electrical currents, geomagnetic field geometry, ionospheric electrodynamics, ion-neutral coupling, temperature and winds in the neutral atmosphere. This session solicits papers on recent advances in space physics, aeronomy and space weather focusing on polar cap dynamics. Studies discussing observations or modeling results that place polar dynamics in global context are highly encouraged.
