When the air reaches the mountain or escarpment slopes, it is forced to rise with the elevation of the physical terrain. The upward currents force the aircraft up its normal landing path, resulting in a touch beyond the desired point (overrun). Temperature inversions are zones with vertical wind shear potential. mountain from the leeward side, a pilot should gain enough altitude well Dependent upon the stability of the air mass, this may result in triggering convection, with its attendant turbulence; it also may generate gravity waves, referred to in that case as mountain waves, or may tend to return the airflow to its original level giving standing waves and rotors. Plateau. Those downdraughts usually are caused by cool air sinking in the surrounding rising warmer updraught air. Factors influencing climate.

Maintain, or increase, pitch attitude and accept the lower-than-normal airspeed indications. But a region's topography, like the orographic effect, also plays a large role. When the change in wind speed and direction is pronounced, quite severe turbulence can be expected. The terrain is key to the development of the downwind cirrus in that wave produced by the mountain range is transmitted to upper levels as shown in the diagram. Ordinarily, this can be avoided by flight at higher altitudes. The calculation algorithm represents the critical amplitude approach for gravity waves and allows identifying zones of mountain wave breaking that generate turbulence.
