Meteorological analyses from synoptic to mesoscales are combined with wind and cloud observations from the new French‐German airborne Doppler lidar WIND to analyse the dynamics of an upper‐tropospheric jet‐streak. The results show the impact of ageostrophic circulations on mesoscale structure as observed by the lidar. Lidar data also reveal fine scale heterogeneities (horizontal wind shear over <40 km) at the edge of the jet streak associated to a structural modification of cirrus clouds.
