ionosphere-thermosphere (IT) is hardly ever a mirror image of the other hemisphere even when considering differences due to season and Earth’s magnetic field. Among others, neutral density and plasma distribution, exhibit interhemispheric asymmetries (IHA)
on temporal scales from hours to seasonal. Forcing from both magnetosphere-ionosphere (MI) coupling and lower atmosphere can contribute to IHA but it is still not well understood. The effect of the strong high latitude energy deposition on the IT system can
be modulated by the background atmospheric state which is strongly affected by the vertical coupling to the lower atmosphere. Meanwhile, during meteorological disturbed conditions, strong variations in the wave spectrum and the background conditions lead to
significant changes in the mesosphere-lower thermosphere (MLT) and IT system. In this workshop we solicit studies based on observations and/or models to improve our understanding of the generation (from both above and below) and impacts of IHA.</span></span><span style="font-family:"Times New Roman",serif;color:black"><o:p></o:p></span></p>
