Mountain waves are formed when four requirements are met. When these factors coincide with jet streams, CAT can occur: A mountain range, not an isolated mountain Strong perpendicular wind Wind direction maintained with altitude Temperature inversion at the top of the mountain range Se mer In meteorology, clear-air turbulence (CAT) is the turbulent movement of air masses in the absence of any visual clues, such as clouds, and is caused when bodies of air moving at widely different speeds meet. The atmospheric … Se mer In meteorology, clear-air turbulence (CAT) is the turbulent movement of air masses in the absence of any visual clues, such as clouds, and is caused when bodies of air moving at widely … Se mer At typical heights where it occurs, the intensity and location cannot be determined precisely.
