Scientific paper

It is shown to what extent qualitative and quantitative deductions about solar-wind and interplanetary magnetic-field parameters can be made from existing geomagnetic records. Qualitative inferences are discussed which indicate significant long-term changes in the solar-wind velocity, the magnetic-field strength, the variability of the field, or some combination of these. A heliographic-latitude dependence is found for these three parameters whose amplitude depends on sunspot number. Little north-south asymmetry is observed in these parameters, and evidence is presented for a double sunspot-cycle modulation of geomagnetic activity. It is proposed that this modulation results from a modulation of the interplanetary magnetic-field polarity with solar latitude, which implies the existence of a solar polar magnetic dipole. Changes in the amplitude of the geomagnetic modulation are discussed, and it is concluded that quantitative inferences about interplanetary conditions cannot be made on the basis of geomagnetic records.
