A wavelet analysis of solar mean magnetic field measurements
(2002) 2nd Solar Cycle and Space Weather Conference 477. p.79-82- Abstract
- Solar mean magnetic field (SMMF) measurements from the Wilcox SolarObservatory and with SOHO/MDI are analyzed using continuous wavelettransforms, SMMF variability is found at a number of temporal scales.Detected SMMF variations with a 1-2 year period is considered to belinked to long-term variations in the internal rotation of the Sun.Intermediate SMMF oscillations with a period of 80-200 days are probablyconnected to the evolution of large active regions. We also findevidence for 90 minute variations with coronal mass ejections as aprobable origin.
