The global interactions with, and (in some cases) resultant escape from various planetary bodies are studied by numerical simulations.
We also include a detailed examination of the code's performance on planetary disk planet interactions.
There are in addition day-to-day changes in tides resulting from variations in forcing, changes in zonal mean propagation conditions, and planetary wave interactions that further add to tidal variability.
Major inconsistencies are revealed, motivating the need for models that realistically address troposphere heating and nonlinear tide-planetary wave interactions as tidal sources.
As a linear tidal mode, the GSWM cannot account for nonlinear processes, such as planetary wave/migrating tidal interaction forcing.
Several mechanisms can cause the longitudinal variations in EEJ strength: tidal effects in the ionosphere, low-latitude signatures of magnetic activity, planetary wave oscillations, interaction of gravity waves and non-migrating tides and day to day variability of zonal winds.
In addition, for rapidly rotating systems such as planetary bodies, the interaction of magnetic fields with convection can result in the possibility of distinct weak- and strong-field regimes (see, e.g., section 2.3.3 of Rüdiger and Hollerbach 2004), possibly of relevance to the dynamics of the geodynamo and of other planetary dynamos.

Integrated models are important tools to investigate the interactions between planetary processes and the growing impacts of human populations – in short: global change.
The 12-h wave showed stronger variability during the 1995/1996 winter season, which may be related to nonlinear interactions with planetary waves.
