Summary

The equatorial electrojet is considered as a possible source of low frequency TID's. Calculations are made to investigate the shape and strength of such disturbances which may be launched through the Lorentz coupling of the electrojet to the neutral atmosphere. It is concluded that such coupling is very much weaker in the equatorial region than is the case at auroral latitudes. An order of magnitude comparison of the Lorentz, and Joule heating, coupling strengths indicates that the former dominates the TID generation except perhaps in the most severe storms.
