Thermosphere Semi-annual Variation WACCM MSIS 1.73E-5Pa ~250 km 120km Compare 250km results Compare 120km Thermospheric variability 120 km (Courtesy Fuller-Rowell, 1998)

Short-term Variability Why is MLT an interesting region: interface between the lower atmosphere and thermosphere. Complex variability from both regions.

Summary and Future Studies The extended WACCM reproduces salient features of Atmospheric composition, temperature and wind of the whole atmosphere. Semi-annual variation in the thermosphere. Tides Migrating components: weaker than observed. Test with higher vertical resolution (.25 scale height) yields results in good agreement with observations. E3 diurnal--comparable to observed. Further analysis of thermospheric variability as related to the coupling with the lower atmosphere. Further development to include ionospheric electrodynamics. We would like to report that the extended WACCM is up and running now. What’s being planed?
