    Mountain Waves - SKYbrary Aviation Safety

    An aircraft tracking perpendicularly across, or downwind of, a mountain range or a significant mountain ridge experiences a sudden loss of altitude followed by a significant and sudden reduction in airspeed during severe turbulence.

    Mountain wave turbulence - ATSB

    Mountain waves are the result of flowing air being forced to rise up the windward side of a mountain barrier, then as a result of certain atmospheric conditions, sinking down the leeward side.

    What causes turbulence in mountains?
    When a parcel of air within a stable air mass moves over a mountain, it undergoes wave motion, resulting in a gravity wave with up-and-down motions. Gravity waves can grow in amplitude until they break into turbulence. If the wind shear exceeds a critical value, turbulence will occur.

    Can parallel mountain wave forecasts predict turbulence?
    Comparison with pilot reports has shown that this parallel mountain wave forecast tends to over-predict turbulence. Specially in the light-to-moderate ranges. Over predicting turbulence is much better than under-predicting it, since it means that the data available to pilots will be on the safe side.

    Are gravity-shear waves associated with aircraft turbulence?
    Although gravity-shear waves are not typically associated with the magnitude of aircraft hazard represented by mountain waves, they are a frequent contributor to turbulence at altitude and are occasionally associated with aircraft reports of moderate-to-severe turbulence (Bedard et al., 1986).

    What type of wave does a mountain ridge create?
    A mountain ridge creates vertically propagating mountain waves and trapped lee waves. The passage goes on to explain that both types of waves can be hazardous to aviation operations in the AC 00-57 Hazardous Mountain Winds document by the Federal Aviation Administration.

    What is turbulence in aviation?
    Turbulence in aviation refers to relatively rapid onset turbulence associated with orographic winds that can be encountered by turbine-powered aircraft operating at cruise altitudes above flight level (FL) 180 in the vicinity of mountainous terrain. This type of turbulence can lead to structural damage or airframe failure.

    What happens when a mountain wave is formed?
    When a mountain wave is formed, lenticular clouds can appear at the mountain top and at the top of the waves. When spotting such pattern, pilots have a clear warning that mountain waves could be in the zone.

    Atmospheric Turbulence: Mountain Waves - turbli

    Mar 1, 2021 · Mountain wave turbulence can be found in many parts of the world: the Andes, Rockies, Antartic peninsula, Scandinavia, etc. The large turbulence in the rotors and wave breaking areas make it a hazard for planes.
