SHOCK WAVE. “As the solar wind flow past the magnetosphere is both supersonic and super-Alfvénic, a bow shock is formed upstream of the magnetopause, and the flow is decelerated within the magnetosheath between the shock and the magnetopause.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

BOW SHOCK. “The low-density tail lobes in the nightside magnetotail connect magnetically to the high-latitude polar caps at one end and to the interplanetary field at the other end. The effects of the strong dipole are not seen tailward of about 20 RE. Beyond that distance, the fields in the northern and southern tail lobes are nearly antiparallel and have an almost constant intensity of about 20 nT over a long range of distances from the Earth.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

MAG FIELD SHAPE. “The plasma sheet separating the northern and southern lobes hosts densities of the order of 1 cm−3 and partially very low magnetic field values reaching only a few nT. Thus, while the plasma beta (ratio of plasma and magnetic pressures, β = 2 μ0p/B2) is very low in the tail lobes, it generally exceeds unity at the center of the field reversal region.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

CHAOTIC CORE. “The inner part of the plasma sheet with its weak field and at times intense cross-tail current sheet is highly variable with bursts of fast flows, magnetic reconnection, and large-scale reconfiguration events.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

TRAPPED PARTICLES. “In the inner magnetosphere, particles can become trapped on closed orbits drifting around the Earth guided by the quasi-dipolar intrinsic field. The ring current located roughly at 4–6 RE radial distance encircles the Earth with highly variable intensity also modulated by the level of geomagnetic activity.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn
