大功率高频泵波加热电离层中,泵波反射高度区域是除了D,E层外的另一个主加热区.文中将在磁子午面内建立中低纬度地区泵波加热电离层中泵波反射高度处的二维模型,分别给出早晚两个时间模拟加热结果.根据模拟结果可知,整个泵波反射高度区域电子温度强烈上升,而泵波反射点周围电子浓度反而下降,该电子浓度空洞沿磁力线上下区域内电子浓度小幅上升,呈现出明显的场向特征.夜间模拟加热效应比早上更加明显,夜间、早上模拟平面内最大电子浓度变化率分别为-13%和-3.6%,电子温度变化率分别为88%和22%.另外在早晚的模拟加热中,电子浓度稠团和空洞随时间的变化也有明显的不同.由此可见,在高频泵波加热电离层中,加热结果随电离层初始条件的不同而明显不同.
High-power high-frequency pump wave heating ionosphere, the pump wave reflection height area is in addition to the D, E layer outside of the other main heating zone.This paper will establish a mid-low temperature region of the mid-low temperature region of the pump wave heating ionosphere pump According to the simulation results, the electron temperature rises sharply in the reflection height region of the pump wave, and the electron concentration around the reflection point of the pump wave drops instead. The electron concentration is hollow The electron concentration in the upper and lower regions along the magnetic line increased slightly, showing obvious field characteristics. The nighttime simulated heating effect was more obvious than that in the morning, and the rate of change of the maximum electron concentration in the simulated plane at night and morning was -13% and -3.6% respectively. The rate of change was 88% and 22% respectively.In addition, in the morning and evening simulated heating, the electronic concentration of dense groups and voids also significantly different with time.Thus, in the high frequency pump heating ionosphere, the heating results with The initial conditions of the ionosphere are distinctly different.
