Abstract
MEAD1 calculated the diurnal magnetic-field variations caused by the impingement of the solar plasma wind on the terrestrial magnetosphere. The current sheet produced at the magnetospheric boundary leads to a perturbation of the dipole field throughout the magnetosphere and on the ground. A surprising result is that the computed field variations, in fact, all three components, qualitatively follow the observed diurnal variations, which are commonly ascribed to dynamo-electric effects in the ionosphere. The computed magnitude, however, is too small for an identification with the observed variations.
