Solar wind magnetosphere coupling
WebFeb 1, 2024 · Abstract Solar wind-magnetosphere coupling functions have now been in use for almost 50 years. In that. time, a very large number of formulations hav e been proposed. As they become increasingly ... WebFeb 28, 2024 · On the other hand, the quasi-viscous interaction via Kelvin-Helmholtz waves/vortices was proposed to lead to the solar wind entry and magnetospheric convection. Since then, the two processes have been thought to regulate the solar wind and earth’s magnetosphere coupling.
