Auroral currents have been recognized in the past both theoretically and observationally, as a probable source of atmospheric gravity waves and of associated travelling ionospheric disturbances (TID's). A model calculation is performed here, by which the magnitude and form of the anticipated atmospheric wave train may be assessed. Both are found to be consistent with observations already recorded. The question, as to whether the Lorentz force or the Joule dissipation is the more important exciting agency provided by the current, is left unanswered because of present uncertainties connected with the nature of the current itself.
