摘要
Recently a Three-dimensional EquatoriaL spread F (TELF) model using high-resolving power advection schemes has been developed at the University of Science and Technology of China (USTC). With the inclusion of the field-aligned plasma flow and realistic ionospheric conductivity configuration, the TELF model reproduced typical features of the observed ESF phenomena, including plasma depletions along flux tubes, geomagnetic conjugate irregularities, and ESF morphology as seen in ground optical and satellite observations. Through control simulations, the effects of field-aligned plasma flow and ionospheric conductivity on ESF are investigated. It is found that field-aligned plasma flow could inhibit the growth of bubbles by modulating the ionospheric conductivity distribution along field lines, and the plasma bubbles from TELF model behave more physically in the topside F-region than those from the 2D model due to the realistic ionospheric conductivity specification. Additionally, the simulations demonstrate that the amplitude and altitude of the initial perturbations can also affect the growth rate of ESF through modulating the polarization electric fields.
