ABSTRACT=Solar wind (SW) quantities, referred to as coupling parameters (CPs), are often used in statistical3
studies devoted to the analysis of SW-magnetosphere-ionosphere couplings. Here the CPs and4
their limitations in describing the magnetospheric response are shortly reviewed. We argue that a5
better understanding of SW magnetospheric interactions could be achieved through estimations6
of the energy budget in the magnetosheath (MS), which is the interface region between the7
SW and magnetosphere. The energy budget involves the energy transfer between scales,8
energy transport between locations and energy conversions between electromagnetic, kinetic9
and thermal energy channels. To reach consistency with the known multi-scale complexity10
in the MS, the energy terms have to be complemented with kinetic measures describing11
some aspects of ion- electron-scale physics.
