(a) Latitude-vertical cross-section of the GW meridional wind perturbation along 95°W from the surface to 300 km at the same time as in Figures 1 and 2. (b, c) Same as (a) but for the southward and northward propagating GW perturbations, respectively. (d) Vertical velocity at 500 hPa (~5 km) in pressure coordinates (Pa/s) along 95°W at the same time as (a–c). See Movie 2 of the GW meridional winds along 95°W at 16.33–22.33 UT for supporting information.
