Abstract.In experiments on active influence on an ionosphere powerful short-wave complexes -heater stands are used. As a result of such influence the set of the physical processes [1] which studying represents scientific interest is formed. One of them is formation artificial fieldaligned irregularities. Studying properties natural field-aligned irregularities on Kamchatka [2], authors have come to a conclusion about possibility of realisation of the received approaches in their studying, on short-wave lines of the big extent. In work results of supervision on Kamchatka of displays of active influence on an ionosphere in Tromse (Norway) are resulted.

Abstract.Recently the significant increase in intensity of researches in the field of the fissile impact on geophysical processes in various environments is noted. Special attention is paid to a research of impact on an ionosphere of a potent short-wave radio emission of heating stands.
