Short summary
Radar observations of the E- and F-region ionosphere from the Arecibo Observatory made during moderately disturbed conditions are presented. Plasma irregularities in both ionospheric regions were observed. We investigate the role of neutral atmospheric dynamics and instabilities in causing the ionospheric disturbances. A number of viable instability mechanisms rooted in neutral dynamics are identified.
