| 英文摘要 | With a theoretic ionospheric model, we simulate semiannual variations of the ionospheric F2 region peak electron density (NmF2) at mid- and low latitudes under the low solar activity and quiet geomagnetic conditions, and focus on how electric fields modify the semiannual component of NmF2. The result indicates that when the input electric fields have no semiannual variation, the NmF2 at the geomagnetic equator still exhibits some semiannual component, and the amplitudes of the semiannual component. become smaller as the latitude increase. When the input electric fields have a semiannual component to some extent, the amplitudes of the NmF2 semiannual component is strongly modified, and this influence seems to be much different at different magnetic latitudes. It is also found that the modification of electric fields on the NmF2 may have a close relationship with the 'fountain effect' in the equatorial ionosphere. |
