Context. Solar cycles vary in their amplitude and shape. There are several empirical
relations between various parameters that link the cycle's shape and amplitude, foremost …

Context. Solar activity cycles vary in amplitude and duration. The variations can be at least
partly explained by fluctuations in dynamo parameters. Aims. We want to restrict uncertainty …

By using the sunspot time series as a proxy, we have made a detailed analysis of the mean
solar magnetic field over the last two and half centuries, by means of a reconstruction of its …

Manifestations of the solar magnetic activity through periodicities of about 11 and 2 years
are now clearly seen in all solar activity indices. In this paper, we add information about the …

Solar activity has a cyclic nature with the≈ 11-year Schwabe cycle dominating its variability
on the interannual timescale. However, solar cycles are significantly modulated in length …

Aims. We aim to characterise the solar cycle progression simultaneously at different latitudes
in each solar hemisphere using solar magnetic field data provided by the Wilcox Solar …

The paper presents a study of a solar dynamo model operating in the bulk of the convection
zone with the toroidal magnetic field flux concentrated in the subsurface rotational shear …

In this work we present the possible variations that the meridional circulation of the Sun
might have undergone during the last 250 years. In order to do this, we reduce an\alpha …

Context. The hemispheric asymmetry of sunspot activity observed possesses a regular
component varying on a timescale of several solar cycles whose origin and properties are …

The evolution of solar activity comprises, apart from the well-known 11-year cycle, various
temporal scales ranging from months up to the secondary cycles known as mid-term …
