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.
