The Atmospheric Diffusion in the Horizontal Direction in Relation to Finite Sampling Period

[摘要] The average dispersion rate of atmospheric diffusion from a fixed point can be expressed as a function of the traveling time and the observation time using a spectral representation for the behavior on the smoke plume.A spectral form for the eddy diffusivity in the cross-wind direction leads to a conclusion of depending upon the traveling time and the sampling period for a time mean concentration.
