Solar Activity, Geomagnetic Field and Terrestrial Weather.
Abstract
There is strong evidence for a casual connection between the interplanetary magnetic field and geomagnetic activity, and some evidence for a connection (possibly indirect) between the interplanetary magnetic field structure and atmospheric vorticity. The interplanetary magnetic field originates in the sun and exhibits long-lived sector structure with a fairly well defined synodic rotation period of approximately 27.1 days. It would therefore appear that an independent test of these associations could be obtained by means of spectral analysis. A comparison of least-squares spectra reveals a feature, with period of order 27.1 days, common to both the geomagnetic activity index and the vorticity area index, lending support to the hypothesis that the sun can affect day-by-day terrestrial weather.
