The Effects of a Geomagnetic Storm on Thermospheric Circulation.
Abstract
The motions of the thermosphere and its interactions with the ionosphere during a geomagnetic storm are of current interest to space scientists. A two dimensional model was used to simulate the thermospheric response to the impulsive high-latitude heating associated with a geomagnetic storm. The storm-induced motions can be characterized by an initial period of transient waves followed by the development of a mean circulation. These motions generate an electrical current system that is on the same order of magnitude as, and in the opposite sense to the normal s sub q current system. Model-simulated winds and electrical currents were then compared to observations.
