It is noted that the midlatitude winds at F-region altitudes measured by Hernandez and Roble (HR, 1978) near Boulder, Colo., during a magnetic substorm are a clear indication of energy input into the thermosphere associated with development of the ring current. This paper demonstrates that the specific ring-current decay mechanism invoked by HR to explain the association fails because a correlation of energy input to the atmosphere, or of wind velocity, with positive values of d(Dst)/dt is needed to support it, but HR found a correlation of wind velocity with negative values of d(Dst)/dt. The basic idea that energy associated with the ring current is an important component of mid- and low-latitude thermospheric heating is shown to be supported by other data, including the apparent divergence of the winds observed above Boulder. It is suggested that an energy-input mechanism involving energetic neutral-atom precipitation arising from charge-exchange neutralization could be more energetic than hitherto inferred, and, in combination with auroral-zone heating and one or more other heating mechanisms, could explain the observations.
