Study of the solar wind coupling to the time difference horizontal geomagnetic field

The local ground geomagnetic field fluctuations (Δ <i>B</i>) are dominated by high frequencies and 83% of the power is located at periods of 32 min or less. By forming 10-min root-mean-square (RMS) of Δ <i>B</i> a major part of this variation is captured. Using measured ge...
