A TRANSIENT PROCESS IN THE AURORAL ELECTROJET
-
摘要: 本义分析了极光电激流建立阶段的物理过程,认为在此期间存在着一个正反馈,从而导致一种暂态过程的产生。使用一种简化的物理模型,模拟了极光电激流在建立阶段的物理过程,计算结果表明,极光电激流中的暂态过程确实存在,电流、净电荷和电导率在治极光电激流的方向上均存在着传播的阶跃结构.计算结果与有关观测资料符合得很好.Abstract: In this paper, the building prare of the auroral electrojet was analytal and it was consided that there is a posihve feedback, therefore a transient process during the building pedod' To probe the physics mecanism, a simple model was utal in this paper to sdriulate the building of the auroral electrojet. The results show that there does be a transient process in the auroral electrojet. The structure along the eleCtrojet of curmt, net charge or conductivity is a propagahng jump, whereas the elecric field kaps neariy invariable.The calculatal results agree to the observahons rather well.
