F-region drift current distribution by X wave ionospheric heating

Yong Li, Hui Li, Jian Wu, Xingbao Lv, Chengxun Yuan, Ce Li, and Zhongxiang Zhou

Abstract. We present a theoretical and numerical study of drift current model in the ionosphere by incorporating the ohmic heating model and the magnetohydrodynamic (MHD) momentum equation. Based on these equations, the ionospheric electron temperature and drift current are investigated. The results indicate that the maximum change of electron temperature ΔTe is about 570 K, and the ratio is ΔTe / Te ~48 %. The maximum drift current density is 8 × 10−10 A ⋅ m−2, and its surface integral is 5.76 A. Diamagnetic drift current is the main form of current. The low collision frequency between charged particles and neutral particles has little effect on the current, and the collision frequency of electrons and ions is independent of the drift current. The current density profile is a flow ring. We present the effective conductivity as a function of the angle between the geomagnetic field and the radio wave; the model explains why the radiation efficiency in Kotik's experiment was strongest when the X wave is heating along the magnetic dip angle.

Short summary
According to the plasma drift theory, charged particles will drift when they are subjected to external forces, thus generating a drift current. In this paper, we give the formula of drift current in F and analyze the properties of drift current such as magnitude and distribution, and explains the effect of the heating wave and magnetic field angle on the drift current. This work establishes the basis for the excitation and propagation of ELF waves in the ionosphere.
