Although interesting in its own right, due to the ever-increasing use of satellites for
communication and navigation, weather in the ionosphere is of great concern. Every such …

The physical significance of recent radar studies of auroral irregularities at different
frequency bands in the VHF and UHF range is discussed, with emphasis on Doppler …

The geomagnetic storm of 17–18 March 2015 was caused by the impacts of a coronal mass
ejection and a high‐speed plasma stream from a coronal hole. The high‐latitude ionosphere …

A plasma wave can be described by its frequency and wave vector, while a nonlinear
plasma structure such as a solitary wave can be described by its temporal signature and …

We have extended the linear fluid theory of electrojet plasma waves to the region where ion
magnetization effects are important. Our general dispersion relation includes the effect of …

The storm onset on 7 September 2017, triggered several variations in the ionospheric
electron density, causing severe phase fluctuations at polar latitudes in both hemispheres. In …

Both primary and secondary two‐stream (Farley‐Buneman) waves have been detected by in
situ electric field and plasma density probes in the strongly driven daytime equatorial …

A new self-consistent non-linear theory of radar auroral backscatter is presented. An
important feature of this theory is a novel treatment of wave heating as an electron-plasmon …

Numerous radar observations demonstrate anomalously strong electron heating in polar
electrojets during magnetic storms. The effect often correlates with the onset of the Farley …

The principles of coherent backscatter from irregularities created by plasma instabilities in
the ionospheric E-region are described in this paper. It is intended as an introduction for …
