Dynamo currents, winds, and electric fields
Listed in National Center for Atmospheric Research
After a brief presentation of Sq and L electric current systems deduced from geomagnetic data, electric conductivities and wind models in the dynamo region are discussed.
Description
It is then shown that the solar negative-mode thermal diurnal tide and the lunar semidiurnal gravitational tide having a phase shift with altitudes produce the best fit Sq and L current systems, respectively. Distributions of electrostatic fields are computed, and electromagnetic drift speeds in the ionospheric F region are also examined.
These calculated values agree well with observed results.
