Unraveling mesoscale auroral dynamics.

A primary question of the Sun-Earth interaction is how the magnetosphere interacts with the ionosphere and the atmosphere. A key tracer of this interaction is the beautiful aurora. Over the last few years we have moved beyond large-scale average understanding of the M-I system into the regime of the mesoscales. In this seminar we present new results addressing unanswered questions in M-I coupling at the mesoscale scale lengths in the context of auroral dynamics.
