magnetospheric convection
Quick Summary
Magnetospheric convection is the circulation of plasma within Earth's magnetosphere, driven by the transfer of momentum from the solar wind. This process involves plasma flowing parallel to the solar wind on the edges of the magnetosphere and returning towards Earth in its interior. This system acts as a secondary magnetohydrodynamic generator, producing significant electrical potential. This convection is crucial for phenomena like the auroral oval, where energetic particles precipitate into the atmosphere, creating the aurora. Magnetic reconnection is a primary driver of magnetospheric convection, more efficiently than viscous interactions.123

Consequently, all phenomena associated with convection are much enhanced over quiet times. Convecting particles approach closer to Earth before they are deflected by drift in the main field.
