• Sq and EEJ—A Review on the Daily Variation of the Geomagnetic Field Caused by Ionospheric Dynamo Currents (2017, methodology): “Cnossen and Richmond (2013), using the Coupled Magnetosphere-IonosphereThermosphere (CMIT) model (Wiltberger et al.”
• Dst model for 1995–2002 (2006, background): “This angle determines, in part, the seasonal dependence of magnetic activity and of the Dst index [Cliver et al., 2000; Li et al., 2001a].”
• Major geomagnetic storms (Dst<=-100~nT) generated by corotating interaction regions in 1996--2004 (2006, result): “Such a pattern is consistent with the expectations of the Russell and McPherron [1973] effect, to which other factors also contribute [e.g., Cliver et al., 2000; O’Brien and McPherron, 2000].”
• The Geomagnetic Kp Index and Derived Indices of Geomagnetic Activity (2021, background): “Thus, Kp contains information both on the solar wind as well as on the coupling between the solar wind and the magnetosphere-ionosphere system (Cliver et  al.,  2000; Russell & McPherron,  1973; Siebert & Meyer, 1996).”
• A comprehensive high‐throughput analysis of substorms observed by IMAGE magnetometer network: Years 1993–2003 examined (2009, background): “Furthermore, the substorm number and peak amplitude show much larger values for winter than for summer, which may be partly due to the fact that themaximum southward component of the interplanetary magnetic field (Bsouth) occurs in February and the minimum occurs in June.”
• A new model for the prediction of Dst on the basis of the solar wind (2002, methodology): “3) The seasonal behavior of the magnetosphere (stronger activity during the equinoxes) is strongly influenced by the angle of the dipole with respect to the solar wind velocity as has also recently been argued [Cliver et al., 2000].”
• Flux Transfer Events: 1. generation mechanism for strong southward IMF (2006, unknown): “The seasonal and diurnal modulation of geomagnetic activity is a well known effect (Russell and McPherron, 1973; Cliver et al., 2000; Hakkinen et al., 2003) and usually attributed to three effects: Changes in heliographic latitude during the year; variations of the solar wind flow direction with…”
• Space weather conditions and spacecraft anomalies in different orbits (2005, background): “Recent statistical studies by Cliver et al. [2000] , Ahn et al. [2000], and Lyatsky and Tan [2003] demonstrated strong differences in the seasonal variations of various geomagnetic activity indices.”
• The Maunder minimum (1645–1715) was indeed a grand minimum: A reassessment of multiple datasets (2015, background): “…semi-annual variation in ge-omagnetic activity (Sabine 1852; Cortie 1912) is mainly caused by the e ff ect of solar illumination of the nightside auroral current electrojets (Cliver et al. 2000; Lyatsky et al. 2001; Newell et al. 2002), leading to equinoctial maxima in geomagnetic activity.”
