[1]等离子体层嘶嘶声是一种电磁波发射负责电子损失的辐射带，特别是在槽区域（2 - 2 kHz，增加与闪光率，是更强的夜面，并在北方夏季达到峰值。波的强度增加与磁活动的所有频率的日侧，但独立的磁活动的夜侧。这些数据表明，在现场放大的波湍流在空间中的波功率低于1 kHz的主要来源，而波功率高于2 kHz的是更相关的闪电产生的哨声。结果表明，自然等离子体湍流应占主导地位的相对论性（约MeV）的电子在槽区2 < L < 3的损失。
[1] Plasmaspheric hiss is an electromagnetic wave emission responsible for electron loss from the radiation belts, particularly in the slot region (2 2 kHz, increase with flash rate, are stronger on the nightside, and peak during the boreal summer. The wave intensities increase with magnetic activity for all frequencies on the dayside but are independent of magnetic activity on the nightside. The data suggest that in situ amplification of wave turbulence in space is the main source of wave power below 1 kHz, whereas wave power above 2 kHz is more related to lightning-generated whistlers. The results suggest that natural plasma turbulence should dominate the loss of relativistic (approximately MeV) electrons in the slot region 2 < L < 3.
