Early Online ReleaseGraphical Abstract with highlights

Plain Language Summary: Aircrafts making landing and takeoff at Narita International Airport in Japan frequently report low-level wind shear (LLWS) with turbulence when the prevailing wind is southwesterly, which is crosswind to the runway direction. This study used observational data by a landing aircraft at the runway 16R and a single-Doppler lidar to demonstrate the existence and structure of horizontal roll vortices (HRVs) causing the LLWS encountered by the aircraft.
