“…However, the nearby radiosonde at 1200 utc showed a layer of low wind speed at a height of 900m, which would be a critical layer in terms of absorbing mountain waves (Worthington and Thomas, ). To explain the contradiction, Sinha suggested that friction and thermals from the windward bare rocky mountain slopes would increase the effective height of the mountain to ≈1km (Worthington, ).…”

Mountain waves are oscillations of stable airflow over mountains which remain roughly fixed relative to the ground as the airflows through them. They are significant to numerical weather models, ozone depletion, and aviation safety. Textbook descriptions of mountain waves assume laminar flow down to the mountain surface, following the classic theory of Scorer. However, there can be a region of non‐wavelike atmosphere under the mountain waves, such as convection, turbulent eddies and rotors in the boundary layer, implying a different paradigm to explain wave launching. This paper reviews how the existence of the atmosphere under the mountain waves was realised in Nazi Germany, where mountain waves were discovered using gliders in 1933 and studied in the run‐up to World War 2.1
