Abstract. The wake of a single wind turbine in complex terrain is analysed usingmeasurements from lidars. A particular focus of this analysis is the wakedeficit and propagation. Six scanning lidars (three short-range and threelong-range WindScanners) were deployed during the Perdigão 2015measurement campaign, which took place at a double-ridge site in Portugal.Several scanning scenarios, including triple- and dual-Doppler scans, weredesigned to capture the wind turbine wake of a 2 MW turbine locatedon one of the ridges. Different wake displacements are categorized accordingto the time of the day. The results show a strong dependence of the verticalwake propagation on the atmospheric stability. When an atmospheric wave isobserved under stable conditions, the wake follows the terrain down the ridgewith a maximum inclination of -28∘. During unstable conditions, thewake is advected upwards by up to 29∘ above the horizontal plane.
