<p class="MsoNormal"><span style="font-size:11.0pt">Mesoscale processes in various space plasma systems are increasingly recognized as a key element affecting dynamics at both global and micro-scales, and mediating cross-scale coupling. Terrestrial ionosphere
and magnetosphere, planetary magnetospheres, solar wind and solar corona, all exhibit dynamical processes that occur at scales significantly smaller than the system size but larger than (although often overlapping with) kinetic scales, which we refer to as
mesoscales. Often, but not always, such mesoscale processes are associated with magnetic reconnection. Examples include bursty bulk flows and dipolarization fronts in the magnetotail, flux-transfer events at the magnetopause, supra-arcade downflows in the
corona or plasma blobs in the heliospheric current sheets, as well as Kelvin-Helmholtz vortices at planetary magnetospheres’ boundaries or in the solar corona, hot flow anomalies or foreshock bubbles upstream of the Earth’s magnetosphere, or plasma patches
in the polar ionosphere. The importance of mesoscales processes stems from their ability to accumulate energy leading to emergent global system responses, but also from their importance in cascading energy from global to micro-scales where it dissipates. A
unifying theme in the study of mesoscale phenomena is that they are equally challenging for numerical modeling and observations; by definition, such studies must be multi-scale and capture global, meso-, and sometimes microscales. This session solicits contributions
that serve to highlight mesoscale phenomena as an intrinsically important element of cross-scale interaction in space or laboratory plasma systems. Presentations resulting from numerical simulations, observations and experiment are all encouraged, including
those that emphasize novel methods of dealing with the above challenges such as data assimilation and machine learning.<o:p></o:p></span></p>
