“…These as well as more recent studies focus on such phenomena as lunar and solar tide‐driven variability [e.g., Lühr et al , ; Lühr and Manoj , ], the reverse electrojet [e.g., Vineeth et al , ], planetary wave signatures [e.g., Parish et al , ; Abdu et al , ], correlations with solar flux [e.g., Briggs , ], and relationships with sudden stratosphere warnings [e.g., Park et al , ]. In the most recent decade, space‐based observations of magnetic field variability have enabled studies that delineate the longitudinal variability of the electrojet [e.g., Lühr et al , ; Alken et al , ].…”
