Comparison of solar activity proxies: eigen vectors versus averaged sunspot numbers
V. V. Zharkova, I. Vasilieva, S. J. Shepherd +1
We attempt to establish links between a summary curve, or modulus summary curve, MSC, of the solar background magnetic field (SBMF) derived from Principal Component Analysis, with…

Oscillations of the baseline of solar magnetic field and solar irradiance on a millennial timescale
V. V. Zharkova, S. J. Shepherd, E. Popova
Recently discovered long-term oscillations of the solar background magnetic field associated with double dynamo waves generated in inner and outer layers of the Sun indicate that t…

Reinforcing the double dynamo model with solar-terrestrial activity in the past three millennia
V. V. Zharkova, S. J. Shepherd, E. Popova +1
Using a summary curve of two eigen vectors of solar magnetic field oscillations derived with Principal Components Analysis (PCA) from synoptic maps for solar cycles 21-24 as a prox…
