Magnetotail Transport and Substorms
Magnetospheric convection is driven by solar wind.
In inner magnetosphere quasi-static convection:
Tail observations with IMP show:
curv B = (b.grad)b
Ion diffusion region
Flow braking and flow shear generate:
Spatial scale of flows
Small expansion, pseudo-breakup 1.4 MLT (4-5 RE)
Auroral streamer (N-S aurora) 0.7 MLT (3-4 RE)
Fast flows transport dipolar field inward:
near-Earth reconnection stops
