Abstract:

ECOM5468atmospheric motion, diffusion, wind, turbulence, equations of motion, stabilityatmospheric density, diffusionThe objective of this study was to demonstrate the extent to which a difference in temperature delta T between two levels near the ground static atmospheric stability and the ratio zL dynamic atmospheric stability is related to other parameters indicative of turbulence and diffusion. The data show, assuming that the rate of diffusion is determined by the intensity of turbulence, that delta T measured through a shallow layer near the ground is not a good indicator of diffusion rates, particularly when the atmosphere is statically unstable. The ratio zL does not appear to be a significantly better indicator for defining atmospheric stability than delta T during highly unstable conditions.
