The wind velocities and eddy diffusion
coefficients are considered to be the realistic value.
The matters which are being a gaseous state are plated out as a result of eddy diffusion which one driving force is decreased by concentration of matters in a vertical direction because of fast occluding by a spreading surface.
Vedeneyev ([MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] 1977) had demonstrated, in particular, that calorific pressure bump of cooling towers at small speeds of a wind can render essential influencing on intensity of eddy diffusion that causes appreciable magnification of ground concentration of an admixture.
An eddy diffusion
coefficient in bulk air ranges from 100 to 10000 ([cm.sub.2]/s).
Sutton's theory of eddy diffusion
and the birth of atmospheric diffusion modeling as we know it today.
The discovery of the persistence of mating trails, necessary for the essential survival tactics of reproduction and the perpetuation of the species, further suggests that, to preserve mating signals, copepods may seek regions where turbulent eddy diffusion
is minimal and stability is high.
It can also be defined as the inverse of the dispersion number, which is dependent on the eddy diffusion
