A session description can be found below. The sessions will consist of invited scene setting talks, contributed lightening presentations, and a combined discussion. <b>We</b> <b>invite you to contribute lightening type presentations of your recent results focusing on IHA</b> caused by magnetosphere-ionosphere and/or lower atmosphere coupling and its IT impact. <u>For scheduling, we request that interested speakers contact one of the conveners by the end of May.</u> We encourage participation and contributions from students and early career scientists.<o:p></o:p></span></pre>

<p class="MsoNormal"><span style="font-size:12.0pt;line-height:106%">In the I-T system, interhemispheric Asymmetries (IHA) take many forms. Observations have revealed that IHA manifested via particle precipitation and conductivity, auroral patterns, substorm
occurrence and locations, field-aligned currents, ionospheric electric potentials, magnetic field geometries, ionospheric and thermospheric neutral and plasma characteristics, and atmospheric waves from the lower atmosphere. Understanding IHA is critical for
understanding the IT system to the forcing from both above and below.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;line-height:106%">Despite the now-known importance and ubiquity of IHA, their properties have not been thoroughly examined or documented. The lack of IHA input to models has prevented simulations from testing
their impact on the global I-T system. Also simulation capabilities for handling IHA are significantly limited. Furthermore, impacts of IHA have not been quantified or reproduced. This workshop focuses on quantifying interhemispheric differences observed in
the IT system and understanding their causes and importance for the upper atmosphere. With the available observations and sophisticated numerical modeling capabilities we are in a bette</span>r position now to study the IHA.<span style="font-size:12.0pt;line-height:106%"><o:p></o:p></span></p>
