This proposal aims to develop theories for a better understanding of the observational results of the ionospheric HF heating experiments, and thus for leading a better planning of future heating experiments. The work will focus on: (1) the role of secondary parametric instability processes together with nonlinear scattering processes on the generation of secondary stimulated EM emissions (SEEs), (2) generation of ELF/VLF waves by thermal instabilities excited in heater-modulated electrojet, (3) new spectral features of plasma lines enhanced by obliquely incident HF heater, and (4) physical process responsible for the generation of energetic electrons in the context of weak turbulence theory.***

本研究旨在为更好地理解电离层高频加热实验的观测结果，从而更好地规划未来的加热实验提供理论依据。工作重点是：(1)二次参数不稳定性过程和非线性散射过程对二次受激电磁发射（SEEs）产生的作用；(2)加热调制电射流中激发热不稳定性产生ELF/VLF波；(3)斜入射HF加热器增强等离子体谱线的新光谱特征；(4)弱湍流理论背景下高能电子产生的物理过程
