“…Much work has been recently devoted to improving collision efficiencies and providing refined statistics that are of importance to the collisional processes. Many aspects have been covered, including the flow modifications due to the collected particles [14,15], the statistics of impact velocities [16], fluctuations in the particle concentration [17], the effect of a large Reynolds number of the collector [18], the presence of turbulent fluctuations in the surrounding fluid [19,20], the outcomes of elastic rebounds [21], and the fluid-structure interaction between the collector and the flow [22]. However an effect of particular importance to atmospheric applications has been neglected so far.…”
