Planetary Wave Modulation of Gravity Waves Over the Andes in 2016 Open
The Andes account for the largest source of orographic gravity waves (GWs) in the middle atmosphere. This results from persistent, strong zonal winds at the surface encountering the north‐south mountain chain, producing strong orographic l…
