哨声模式合唱波散射的俯仰角和能量扩散率与波的磁场强度成正比，并且强烈依赖于波的频率分布以及电子等离子体频率（fpe）和电子回旋频率（fce）之间的比率。相对论电子最容易与低带合唱（0.1 300 nT）相互作用。在这些地区的增强波可以发挥重要作用，在电子加速到相对论能量在长期的亚暴活动期间。
Pitch angle and energy diffusion rates for scattering by whistler‐mode chorus waves are proportional to the wave magnetic field intensity and are strongly dependent on the frequency distribution of the waves and to the ratio between the electron plasma frequency (fpe) and the electron gyrofrequency (fce). Relativistic electrons interact most readily with lower‐band chorus (0.1 300 nT). Enhanced waves in these regions could play a major role in electron acceleration to relativistic energies during periods of prolonged substorm activity.
