Abstract:

Mead has derived the diurnal magnetic-field variations caused by the solar plasma wind under the assumption of a resting magnetosphere Corotation of the magnetosphere with the earth and deformation by the solar plasma wind lead to hydromagnetic processes in the magnetosphere. The accompanying electric field strength causes earth currents, which enhance the variations of the diurnal magnetic field and make them better agreeing with observed variations. Land-sea effects are briefly discussed. Author
