## Abstract

A simple formula for calculating dispersion from a

continuous finite line source, placed at right angles to the

mean wind direction, is derived on the basis of statistical

theory. Comparison is made with the virtual source concept

usually used and this is shown to be correct only in the limit

where the virtual time lag Tv is small compared to the timescale

of the turbulence t
