Fig. 2From: Longitudinal structures of zonal wind in the thermosphere by the ICON/MIGHTI and the main wave sourcesThe altitude–month distribution of amplitude of WN1–WN4 in the altitude range of 100–300 km at three latitudes (\(15^\circ \, \text {N}\), \(25^\circ \, \text {N}\), and \(35^\circ \, \text {N}\)). The layout of each subplot is similar to Fig. 1. a–l Represent the altitude–month distribution of amplitude of WN1–WN4 at \(15^\circ \, \text {N}\), \(25^\circ \, \text {N}\) and \(35^\circ \, \text {N}\), respectivelyBack to article page
