这个项目将利用动力学模拟来模拟极光电离层中的波动湍流。模拟是由Freja和FAST卫星的高分辨率观测以及探空火箭推动的。重点将放在两种最常见的波浪模式的非线性演化和饱和:低杂波和朗缪尔波。模拟和伴随的理论分析将处理湍流波的演化和饱和的所有阶段。为了实现这些目标,模拟将建立在现有的计算机代码在先前的NSF支持下开发。
英文摘要
This project will utilize kinetic simulations to model wave turbulence in the auroral ionosphere. The simulations are motivated by high resolution observations from the Freja and FAST satellites, as well as by sounding rockets. Emphasis will be placed on the nonlinear evolution and saturation of two of the most commonly occurring wave modes: lower-hybrid waves and Langmuir waves. The simulations and the accompanying theoretical analysis will treat all phases of the evolution and saturation of the turbulent waves. To accomplish these goals, the simulations will be built upon existing computer codes developed under prior NSF support.
