Scientific paper

Traveling Atmospheric Disturbances (TAD’s) are studied with a 3-D high-resolution (1°x3°) global thermosphere/ionosphere model to determine the importance of the high-latitude production mechanisms contained in the model. The possible production mechanisms are the oval size, the precipitating electron characteristic energy and energy flux, and the cross polar cap potential. The production mechanisms are pulsed at a one-hour period, as was observed in a recent long-duration geomagnetic storm. With auroral pulsation a TAD is generated that propagates equatorward away from the high-latitude auroral oval, depositing energy and transporting mass and momentum into the mid- and low-latitude thermosphere system. Depending on the amount of energy input into the high-latitude auroral zone, the TAD may travel to mid-latitudes, low-latitudes, or if sufficient energy is deposited, the TAD may even propagate across the opposite pole. These and other aspects of TAD generation will be shown.
