| Zusammenfassung |
| A fully time-dependent ionospheric convection
model, in which electric potentials are derived by an analytic solution of
Laplace's equation, is described. This model has been developed to replace the
empirically derived average convection patterns currently used routinely in the
Sheffield/SEL/UCL coupled thermosphere/ionosphere/plasmasphere model (CTIP) for
modelling disturbed periods. Illustrative studies of such periods indicate that,
for the electric field pulsation periods imposed, long-term averages of
parameters such as Joule heating and plasma density have significantly different
values in a time-dependent model compared to those derived under the same mean
conditions in a steady-state model. These differences are indicative of the
highly non-linear nature of the processes involved. |
