| 英文摘要 | The phenomena of localized plasma density enhancements are studied using the plasma density data from DMSP F15 satellite, ROCSAT-1 satellite and the dual-frequency GPS data from IGS receivers at low latitude. The observation of GPS-TEC can also reflect this kind of plasma density enhancement. The four case studies indicate that this kind of plasma density enhancements is mainly located at about +/- 10 degrees similar to +/- 20 degrees magnetic latitude region, while the plasma density enhancements can also occasionally occur at the topside ionosphere near the magnetic equator. Similar to plasma bubbles, the localized plasma density enhancement often occurred after 21 :00LT. It also can be observed at post-midnight. The observation indicates that plasma density enhancements occur when the vertical drift velocity has an upward perturbation at pre-midnight, or before the vertical downward drift velocity reversed at post-midnight. It is suggested the eastward electric field plays an important role in the production of the plasma density enhancements and plasma bubbles. |
