Research Overview

Magnetospheric dynamics at Earth are primarily driven by coupling between the magnetised solar wind and the magnetospheric magnetic field and plasma. This coupling is highly variable and strongly controlled by the relative orientation of the interplanetary and magnetospheric magnetic fields.Many studies have revealed that the magnetosphere has a non-linear response to solar wind drivers. During periods of enhanced solar wind driving, magnetospheric activity ceases to increase in line with increasing driving conditions, an effect known as “saturation”. No consensus has been reached over the cause. I will be analysing measurements made by the ESA Cluster spacecraft to confirm or discount the non-linear response of the system to interplanetary drivers.
