Fundamental to the understanding of high-latitude ionospheric behaviour is an appreciation of the convection electric field and its consequences. This electric field drives a number of processes which directly influence the plasma, including vertical ion drifts, Joule heating and enhanced neutral air velocities. Particle precipitation regions are closely connected with convection boundaries. Universal time variations can, in many cases, be directly related to the diurnal variation of the convection electric field in the geographical frame. Convection also has a profound influence on the interpretation of observations, because understanding why plasma densities have their observed characteristics requires knowledge of the past history of the observed plasma. This past history is determined by the convection electric field, as it transports plasma between regions of differing dominant plasma processes. Where reasonable estimates of the convection electric field exist, numerical models of the ionosphere seem capable of reproducing the characteristics of observed plasma behaviour. This is demonstrated by using the European incoherent-scatter facility’s observations for days for which such estimates are available.

The network for monitoring the high-latitude ionosphere by the method of oblique ionospheric sounding deployed in the Russian Arctic region is considered. The study describes the main results of operational data processing for studying the high-latitude ionosphere and determining the conditions for the optimum operation of radio communication systems and over-the-horizon radars in this region. The study demonstrates the potential of the network as a tool for the remote diagnostics of parameters of small-scale artificial ionospheric irregularities induced by powerful HF radio waves in the mid-latitude ionospheric F-region.
