Scales of atmospheric motion
WebMar 2, 2024 · atmospheric turbulence, small-scale, irregular air motions characterized by winds that vary in speed and direction. Turbulence is important because it mixes and churns the atmosphere and causes water vapour, smoke, and other substances, as well as energy, to become distributed both vertically and horizontally. Atmospheric turbulence near the … WebJan 26, 2001 · The prevailing understanding was that atmospheric circulation variability in the form of the NAO arises from processes internal to the atmosphere, in which various scales of atmospheric motion interact with one another to produce chaotic, large-scale perturbations. Recently there has been renewed interest in the NAO, primarily for three …
