✦ Synopsis

The wind-tunnel data of Hall and co-workers, who measured dense gas cloud concentrations at four sampling positions for a range of six release Richardson numbers, is analyzed to determine the frequency composition of concentration ¯uctuations. It appears, from the furthest and lowest sampling station result, that the spectra approach a self-similar form. Also, the relatively narrow peaks in the spectra are associated with the largest values of contaminant concentration.
