Hemispheric Helicity Trend for Solar Cycle 23 View all abstracts by submitter

Richard Canfield   Submitted: 2001-01-05 09:29

Applying the same methods we used in solar cycle 22, we study active-region vector magnetograms, full-disk X-ray images, and full disk line-of-sight magnetograms to derive the helicity of solar magnetic fields in the first four years of solar cycle 23. We find that these three datasets all exhibit the same two key tendencies - significant scatter and weak hemispheric asymmetry - as were observed in solar cycle 22. This supports the interpretation of these tendencies as signatures of the writhing of magnetic flux by turbulence in the convection zone.
