A simple and relatively general analytic expression for the distributed second central moments of scalar concentration is derived. The ‘fluctuations’ or mean‐square values are given in terms of the mean concentration field and apply in either an inertial or cloud centre‐of‐mass reference frame. Clouds in homogeneous grid turbulence, in the neutral atmospheric boundary layer, and in the inertial sub‐range are used as illustrative examples.
