Orographic gravity‐wave drag over multiple bell‐shaped mountains
Quarterly Journal of the Royal Meteorological Society, Volume 150, Issue 761, Page 2397-2417, April 2024 Part B.Mountains exert a drag on the atmospheric flow through breaking gravity waves, known as orographic gravity‐wave drag (OGWD). We derive OGWD analytically for multiple three‐dimensional bell‐shaped mountains, while previous studies have derived OGWD for a single mountain. We take into account the geometric overlap between the mountains, vertical shear of
