Abstract : Motion of a slightly ionized medium such as the earth's lower ionosphere through a magnetic field such as the earth's permanent magnetic field will result in systematic separation of electrical charges. This charge separation will result in development of an opposing electric field which will balance, in the average case, the force produced by the interaction of the motion and the magnetic field. The D-region fair-weather electric field is defined as the equilibrium field produced by the mean circulation. Asymmetries between the earth's geomagnetic and rotational axes and the structure of the stratospheric circulation are considered in determining global and annual structures of the D-region fair-weather electric field.
