Field-aligned E -region irregularities identified with acoustic plasma waves
Journal Article

· Journal of Geophysical Research
Measurements related to the nature of field-aligned irregularities in the ionosphere E region are presented. The measurements were performed near the magnetic equator, and the irregularities are attributed to the equatorial electrojet. It is shown that the irregularities are most likely to consist of plane acoustic waves generated by an instability resulting from the flow of current in the electrojet. Reference is made to a recent theory in which the existence of such waves is predicted. The characteristics of auroral radar echoes are shown to be similar to those of the equatorial echoes. It is inferred that the auroral field-aligned irregularities are also caused by the flow of electrojets. (auth)
