Plasmaspheric hiss plays an important role in the electron precipitation and the slot formation in radiation belts. Recent studies show the whistler-mode waves can be guided in the density irregularities, performing parallel propagation. Therefore, the resonance between ducted waves and energetic electrons can expand to higher latitudes, and then drive strong energetic electron scattering. In this study, we report a conjugate observation using data from Van Allen Probe A and POES. Through the analysis of observation and the quantification of quasi-linear diffusion coefficients, the results show the ducted hiss can effectively scatter the energetic electrons and drive enhanced electron flux at low altitude region. We suggest the ducted hiss is important for electron loss process in radiation belts.

高密度不规则区域导管嘶嘶声波驱动的高能电子扩散和沉淀


等离子体层嘶嘶声在电子沉淀和辐射带中的槽形成中起着重要作用。最近的研究表明，惠斯勒模式波可以在密度不规则性中被引导，进行平行传播。因此，导管波和高能电子之间的共振可以扩展到更高的纬度地区，进而驱动强高能电子散射。在这项研究中，我们使用来自 Van Allen 探针 A 和 POES 的数据报告了偶联物观察结果。通过观测分析和准线性扩散系数的量化，结果表明，导管嘶嘶声可以有效地散射高能电子，并在低空区域驱动增强的电子通量。我们认为导管嘶嘶声对于辐射带中的电子损失过程很重要。
