Maeda, H., and H. Murata, 1968: Electric currents induced by nonperiodic winds in the ionosphere, 1. J. Geophys. Res., 73, 1077-1092, doi:10.1029/JA073i003p01077.

Electric currents induced by nonperiodic winds in the ionosphere are calculated for the case of incoincidence of the earth's rotational and magnetic axes, based on a realistic model of the upper atmosphere. Main results obtained are as follows: (1) Sq-like current systems changing with universal time are produced, and the intensity of main vortices is about one-tenth of that of the Sq field for a typical wind velocity of 10 m/sec. (2) Of the two components of nonperiodic winds, the meridional component is more effective in producing current systems. (3) The position of main current vortices is controlled by the distributions of ionospheric conductivity and of wind velocity and the degree of influence of these two is different for different profiles of winds. (4) The intensity of main vortices changes with longitude in such a manner that the maximum intensity occurs in the North and South American zone and the minimum in the Asian and Oceanian zone, being in agreement with that of the Sq field. (5) No remarkable difference can be seen in the results obtained by using different coordinate systems.
