利用数值模拟的方法,研究了雷暴放电后,由雷暴电荷、感应电荷和晴天大气的背景电荷共同产生的准静电场(Quasi-electrostatic field,简称QEF)的时变过程,以及准静电场对中性大气的加热和电离.结果表明:在考虑电离层电势和晴天大气背景电场的影响后,时变的准三维的准静电场(QEF)模式能较好地解释"红闪"(Red sprites)的时空特征,特别是能模拟出"红闪"中的一种--"闪晕"(sprite halo)向上弯曲的空间结构. |

A quasi-three-dimensional, time-dependent quasi-static electric field (QEF) model ia developed and is applied to study the effects of QEF on the mesosphere and subionosphere. Using this model we simulate the evolution of QEF produced by thunderstorm source charges, induced charges and fair weather background charges, and investigate the heating and ionization of the neutral atmosphere by QEF. The results show that considering the influence of the ionosphere potential and fair weather background electric field, the quasi-three-dimensional, time-dependent QEF model is able to simulate the total temporal-space characteristics of Red sprites. Particularly, it can reproduce the upward concave shape of sprite halo. |
