Аннотация:This paper reviews individual cases of the relationships between variations of solar windparameters and variations of the DC vertical atmospheric electric field, Ez , and currentdensity, Jz , measured at ground level in the Arctic, at the S. Siedlecki Polish Polar StationHornsund, Spitsbergen (Svalbard, Norway), and at the mid-latitude S. Kalinowski GeophysicalObservatory in Swider (Poland). A considerable number of events from Hornsundconfirmed previous observations of regularity of effects related to the station’s positionagainst the location of the potential bays of ionospheric convection and polar electrojets,observed in other polar locations, as well as effects of other polar cap current systems.This allowed us to conclude that the physical dependence of ground-level Ez and Jz onsolar wind changes produce measurable effects which do not require statistical analysisto be observed. We can also expect that the dependence does exist, especially in stronglydisturbed circumstances, e.g., following solar flares and Earth-directed coronal mass ejections,at middle latitudes. However, further investigations of these physical relationshipsby this approach are practically almost impossible since a very large number of variableparameters simultaneously affect the recorded lower atmospheric variables. In addition,results of quantitative analysis of predicted and observed effects are not satisfactory. Futureresearch studies require more efficient ways of investigation by theoretical treatment andmodelling work using existing and novel observational data besides taking advantage ofscientific progress in magnetospheric physics.
