Parametric Study on Interaction between Superluminous L-O Mode Waves and Radiation Belt Electrons

  • 摘要: 参数化研究了在L=4.5外辐射带区域左旋寻常(Left-hand Ordinary mode, L-O模)的极光千米波与高能电子的相互作用,定量计算了左旋寻常的极光千米波在不同峰值频率、传播角分布和纬度分布条件下的弹跳平均投掷角扩散系数、动量扩散系数和投掷角–动量交叉扩散系数。计算结果表明,动量扩散系数一般比投掷角扩散系数大100倍左右,说明动量扩散在L-O模与电子间的相互作用中起主导作用。随着传播角范围的改变,扩散系数均未发生明显变化,这说明L-O模与电子相互作用的扩散系数对传播角范围的依赖性很小。此外,扩散系数会因为L-O模纬度分布的改变而发生剧烈变化,该结果与之前得到的纬度分布对右旋奇异的极光千米波的影响是一致的。通过参数化研究结果表明,适当条件下,L-O模可能会显著影响外辐射带高能电子的动力学过程。
