| Zusammenfassung |
| This letter presents a study of equatorial F region irregularities using the
NRL SAMI3/ESF model, comparing results using a two-dimensional (2-D) and a
three-dimensional (3-D) electrostatic potential solution. For the 3-D
potential solution, two cases are considered for parallel plasma transport:
(1) transport based on the parallel ambipolar field, and (2) transport based
on the parallel electric field. The results show that the growth rate of the
generalized Rayleigh–Taylor instability is not affected by the choice of the
potential solution. However, differences are observed in the structures of
the irregularities between the 2-D and 3-D solutions. Additionally, the
plasma velocity along the geomagnetic field computed using the full 3-D
solution shows complex structures that are not captured by the simplified
model. This points out that only the full 3-D model is able to fully capture
the complex physics of the equatorial F region. |
