ENERGY FLUX. “In a quiescent situation, energy inflow is gradual, the energy is dissipated in the ionosphere, and magnetic flux opened at the dayside reconnection process is closed by a quasistatic reconnection process in the distant magnetotail at about 100–200 RE from the Earth.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

ENERGY SHEETS. “Energy transfer is most efficient when the reconnection process takes place at the dayside magnetopause, which occurs during periods when the interplanetary field points southward and is thus antiparallel to the intrinsic geomagnetic field.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

ENERGY VENTING. “Variability in the north-south orientation of the interplanetary magnetic field causes episodic energy loading-dissipation cycles termed magnetospheric substorms.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

VIOLENT OUTPUT. “Substorms typically occur at a rate of four to five per day, each lasting typically two to three hours. They are initiated by enhanced dayside reconnection and hence increased energy input to the magnetosphere. This causes a configuration change in the magnetosphere including enhancement of the magnetospheric current systems and formation of a thin and intense current sheet from near-geostationary distance outward.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

MAGNETOSPHERE SHAPE. “The current sheet at the tail center has a thickness of only a few hundred kilometers (comparable to the thermal ion gyroradius), and the magnetic field component normal to the current sheet becomes very small, only a few nanotesla.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

ENORMOUS SCALE. “As this thin current sheet grows unstable, a rapid dissipation process quickly expands to a large-scale reconnection event whose effects are observable over a large portion of the coupled magnetosphere-ionosphere system.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn
