Latest Results from JIM - the UCL Global Circulation Model of Jupiter's Ionosphere and Thermosphere

The UCL global circulation model of Jupiter's thermosphere and ionosphere, JIM, has run for several simulated jovian days. We present the latest outputs of the dynamic, chemical (neutral and ionized) and temperature distributions of our model. These are 3-D, time-dependent calculations and show many important features, including :

(i) The effects of local time, magnetic field orientation and dynamics on the asymmetric, global ionization patterns.

(ii) A transition between `electrodynamic flow' across the polar caps and gas dynamic flow in the equatorial regions.

(iii) The effects of energy transport from auroral to sub-auroral latitudes.
