A three dimensional linear model of orographically forced gravity waves (mountain waves) using realistic topography is used to simulate a high altitude (20 km) ER‐2 encounter with a large mountain wave over Alexander Island (72° W, 69° −72° S). Reasonable agreement between the linear model and observations is obtained if the effects of low‐level flow blocking are taken into account.
