The size of the magnetosphere is controlled by the solar wind dynamic pressure. When the dynamic pressure increases the magnetosphere is compressed and the magnetic field strength in the equatorial regions is enhanced proportionally to the change in the square root of the dynamic pressure. However, Polar observes either an enhancement or depression in the total geomagnetic field depending on where the in situ measurement is made. The most common cause of such changes in the dynamic pressure is interplanetary shocks, and the rise time of Sudden Impulses (SIs) is related to the speed of the shock. We find that the rise time of the SI is dependent on both the propagation speed of the pressure pulse in the solar wind as well as the propagation speed of the compressional front within the magnetosphere. Furthermore, we find that the onset of a substorm can counter the amplification of the magnetic fields and thereby shorten the SI rise time.
