Abstract

Both radar and lidar identified a 6-hour wave that was remarkably coherent during the November campaign. The vertical wavelength of the 6-hour wave estimated from the radar data was 8 to 9 km, the amplitude of the zonal wind component was 10 m s-1, and the amplitude of the meridional wind component was 4 m s-1. The vertical wavelength estiamted from the ground-based and airborne lidar data was 7.3 km, and the amplitude of the scalar horizontal wind ranged from 13 to 16 m s-1. The zonal wavelength of this wave was approximately 772 km, and the intrinsic zonal phase velocity was 35 m s-1 westward. The 6-hour wave was dominated in the height range of 80-90 km, which corresponds to the bottomside of the Na layer. -from Authors
