Abstract The authors have carried out an extensive series of computations using the Coupled Thermosphere-Ionosphere-Plasmasphere model (CTIP), and from this work are able to simulate features of the semiannual variations in the noontime electron density peaking observed in the southern hemisphere at mid latatiudes. When they look at the model in detail they find that the large offset of the geomagnetic axis from the earth`s rotational axis in the southern hemisphere is a major factor in this effect. This offset places South America at close to the geomagnetic equator, and in particular, far from the auroral regions which can provide energy inputs.
