Theoretical Studies on Ionospheric Irregularities, Plasma Turbulence and Electron Acceleration

点击翻译按钮获取中文摘要

This program on ionospheric density irregularities will focus on the fundamental quantitative understanding of the characteristics of plasma turbulence in the E and F regions of the Earth's ionosphere. The main objective will be to develop a self- consistent theory of plasma turbulence driven by the Farley-Buneman instability, which occurs when the cross-field drift velocity of the electrons exceeds the sound velocity. In addition to the main objective, the PIs will investigate the intermittent acceleration of electrons in current sheets that develop because of magnetohydrodynamic activity in the medium.***
