An example case from 12 August 2015. Panel (a) shows a time-height profile of reflectivity from the radar, while (b) presents the atmospheric vertical motion, w a , measured by the Doppler lidar. Panel (c) shows the vertical motion recorded by the radar, w r . For panels (b) and (c) blue colours represent downward motion and red upward motion. The dashed vertical lines in panels (a)–(c) indicate local sunrise and sunset while the solid vertical lines show the cessation and onset of civil twilight. The lower two panels (d) and (e) present a magnified view of the reflectivity and vertical air motion fields outlined by the white boxes in (a) and (b).
