AbstractBased on modeling, we discuss some interactions between the middle atmosphere and thermosphere: (1) Upward propagating tides affect the wind field and the temperature (and density) variations of the thermosphere at higher altitudes. (2) The thermospheric circulations driven by radiative and auroral heating affect the O concentration and temperature of the upper mesosphere through the exchange of chemical energy. (3) Gravity waves excited by auroral processes are ducted through the lower atmosphere and leak back into the thermosphere, permitting them to propagate large distances away from the source.
