| 英文摘要 | The ionospheric conductivity is influenced by solar activities and geomagnetic conditions and has some changes. we calculated the conductivity and the collision frequency between the electrons and ions through models nrlmsise-00 ( neutral atmosphere empirical model-2000) and iri2001 (international reference ionosphere-2001). we discussed the seasonal change of the conductivities at 120 km and 300 km and their changes under different solar activities and geomagnetic conditions. the result shows that the conductivity distribution is affected by the sunlight, and changes with solar activities. the geomagnetic disturbance can affect the ionospheric conductivity, but the effect is smaller than that of solar variations. at 120 km, the geomagnetic disturbance leads to the opposite change between pedersen conductivity and hall conductivity at different latitudes. at 300 km, the geomagnetic disturbance makes the same trend for pedersen conductivity and hall conductivity, and the change extent is bigger than that at 120 km. but the change becomes larger in the direction of pole either at 120 km or 300 km. |
