A Combined Analysis of the Observational Aspects of the Quasi-biennial Oscillation in Solar Magnetic Activity (2014, background): “It has been proposed that such a quadropole-like dynamo may explain the behaviour whereby active longitudes can suddenly shift by 180◦ (Tuominen et al. 2002; Berdyugina and Usoskin 2003; Moss 2004).”
Long-Term Solar Cycle Evolution: Review of Recent Developments (2003, background): “Berdyugina and Usoskin (2003) have shown that migrating active longitudes of sunspot formation are not related to the memory of the dynamo but to an intrinsic feature of the spatial distribution of new sunspots which is persistent throughout the last 130 years.”
Starspots: A Key to the Stellar Dynamo (2005, background): “Shortly after the variability of the Sun in the visual continuum (total irradiance) was established during the Solar Maximum Mission (Willson et al., 1981), evidence for continuum variability among single solartype stars was also revealed (Radick et al., 1982, 1983a,b).”
The Solar Cycle (2007, background): “Bogart (1982) found that this results in a periodic signal that is evident in the sunspot number record.”
What the Sunspot Record Tells Us About Space Climate (2004, background): “Berdyugina and Usoskin (2003) find that the effect is more noticeable with hemispheric data.”

Active longitudes and short-term spot cycle in (2008, result): “The possibility of using active longitudes as tracers for the surface differential rotation is supported by the recent results of Berdyugina & Usoskin (2003) in the case of the Sun, although the properties of solar active longitudes are still object of debate (see, e.g., Usoskin et al. 2007, for…”
