[45.17U] Ion-Drag Effects of Gravity-Wave Heating and Cooling in Jupiter's Thermosphere

D. A. Lamb (Drake University), M. P. Hickey (Embry-Riddle Aeronautical University)

We present preliminary results of a study on the effects of an ionosphere on two propagating gravity waves in Jupiterís thermosphere. A full-wave numerical model is used with two additions: 1) terms to the energy and momentum equations to account for Joule heating, and 2) a realistic, simple electron density profile. We determine that although the effect on one wave is negligible, the heating and cooling rates of the other are increased significantly. This leads to a more substantial contribution of gravity waves to the observed temperature profile than previously determined. This work was funded by the NSF through the Southeastern Association for Research in Astronomy (SARA) REU program.
