Impact Angle Control of Local Intense dB/dt Variations During Shock‐Induced Substorms

Impact Angle Control of Local Intense dB/dt Variations During Shock‐Induced Substorms

Abstract The impact of interplanetary shocks on the magnetosphere can trigger magnetic substorms that intensify auroral electrojet currents. These currents enhance ground magnetic field perturbations (dB/dt), which in turn generate geomagnetically induced currents (GICs) that can be detrimental to p...
