Examples of outstanding challenges include the variable responses to solar wind driving in the auroral zones, polar cap and cusp, each of which has been shown to exhibit phenomenology not captured in the established paradigm of solar wind-MIT coupling. Recent observations of energy deposition and dissipation have raised new challenges in understanding coupling and energy transport across multi-scales. The impact of these observations has not been explored but they can potentially bring a paradigm change to our understanding of the high-latitude dynamics and MIT coupling, and modeling efforts are currently under way. The focus of the Workshop will be on dynamic and cross-scale processes at transition regions of the MIT in a system-wide approach. We invite discussions on satellite, rocket and ground-based observations, and innovative modeling of the coupling processes in the high-latitude regions.<o:p></o:p></span></p><p class=Textbody><span style='font-family:"Calibri",sans-serif'>Cheryl Huang, AFRL (<a href="mailto:huangcyh@gmail.com">huangcyh@gmail.com</a>)<o:p></o:p></span></p><p class=Textbody><span style='font-family:"Calibri",sans-serif'>Olga Verghoglyadova, JPL (<a href="mailto:Olga.Verkhoglyadova@jpl.nasa.gov">Olga.Verkhoglyadova@jpl.nasa.gov</a>)<o:p></o:p></span></p><p class=Textbody><span style='font-family:"Calibri",sans-serif'>Kristina Lynch, Dartmouth (<a href="mailto:Kristina.A.Lynch@dartmouth.edu">Kristina.A.Lynch@dartmouth.edu</a>)<o:p></o:p></span></p><p class=Textbody><span style='font-family:"Calibri",sans-serif'>Robert Gillies, U.
