Ionosphere-Magnetosphere Waves
Abstract
Feedback between the coupled ionosphere and low-altitude magnetosphere gives rise to 'ionosphere-magnetosphere' waves. Understanding these waves and their properties is extremely valuable for interpretation of coupled magnetosphere-ionosphere dynamics, and provides insight, for example, into widening of downward current channels via E-region depletion and the origin of small-scale Alfven waves in large-scale current systems. Here, we present simulations that show the properties of these waves, and analytic results that describe them.
