Weak magnetic storms can modulate ionosphere-plasmasphere interaction significantly: mechanisms and manifestations at mid-latitudes

A comprehensive study of the response of the ionosphere-plasmasphere system at mid-latitudes to weak (Dstmin > -50 nT) magnetic storms is presented. For the first time, it is shown that weak magnetic disturbances can lead to significant modulation of ionosphere-plasmasphere H+ ion fluxes. It is f...

For the first time, it is shown that weak magnetic disturbances can lead to significant modulation of ionosphere-plasmasphere H+ ion fluxes.
