The level of geomagnetic activity is strongly linked to the parameters of the solar wind upstream of the Earth. The nature of the activity is also linked to the upstream solar wind: different regimes of solar-wind parameters result in different types of magnetospheric reaction. A common reaction has a 3-hr periodicity. This can take the form of periodic substorms for typical solar-wind parameters or global sawtooth oscillations for low-Mach number solar wind. The 3-hour length of the period is not a function of solar-wind parameters and the 3-hour length of the perio period is invariant to the level of geomagnetic activity driven by the solar wind. One of the outstanding questions in magnetospheric physics is why the magnetosphere displays a 3-hour periodicity (and sets the period at 3 hours).
