Geomagnetic storms and substorms are a natural hazard similar to hurricanes, floods etc. ... Solar and geomagnetic activity also probably influences the Earth's climate and human health. ... Under southward directed IMF the Earth's magnetosphere is open to input from the solar wind flow. ... Since practical importance of solar wind measurements was recognized, a number of approaches was developed for prediction of the geomagnetic activity basing on the solar wind data. ...
... Plasma sheet is the region of closed field lines in the equatorial magnetotail (however, see also plasmoids ). Plasma sheet is typically divided into plasma sheet proper, or central plasma sheet , and plasma sheet boundary layer (PSBL) , the latter being at higher latitudes adjacent to the tail lobes. ... This is evident both in storms time ring current and substorm time plasma sheet (including late growth and the expansion phases; see, e.g., Daglis et al., ... Res., ... J. Geophys. ...
