Pasquill' s stability classification scheme was developed to describe dispersion conditions using routinely-available, surfaced-based measurements of wind speed, cloud cover and insolation, and more practically to specify the diffusion parameters [sigma] y and [sigma] z(standard deviations of horizontal and vertical pollutant spread) used in the Gaussian plume model. 1, record 1, English, - Pasquill%27s%20stability%20classification%20scheme

In inversion layers, both vertical and horizontal diffusion is inhibited and pollutants become trapped, sometimes for long periods. Low-level discharges of pollutants are more readily trapped by inversions than high-level discharges; furthermore, high-level discharges into an inversion tend to remain at a high level because of the absence of vertical mixing. 2, record 6, English, - vertical%20mixing
