Variations in the polar cap area during intervals of substorm activity on 20-21 March 1990 deduced from AMIE convection patterns
The dynamic behaviour of the northern polar cap area is studied employing Northern Hemisphere electric potential patterns derived by the Assimilative Mapping of Ionospheric Electrodynamics (AMIE) procedure. The rate of change in area of the polar cap, which can be defined as the region of magnetosph...
