Formation of Droplets in a Marine Stratocumulus Layer Containing a Ship-Plume
AbstractA one-dimensional, adiabatic parcel model was used to calculate cloud droplet spectra from airborne measurements made beneath and within a marine stratocumulus layer that contained ship-produced cloud condensation nuclei (CCN). The calculated droplet mean diameters and concentrations matched the measurements but the width of the droplet spectrum was underestimated. New droplet activation, droplet coalescence and mixing should be included to properly simulate the width of the spectrum. The results of the calculations were consistent with the measurements and satellite imagery which suggests the ship-produced CCN were too small and the ambient CCN were too numerous for the ship-produced CCN to affect the stratocumulus layer. Had fewer ambient CCN existed, the ship-produced CCN likely would have increased droplet concentrations and decreased droplet sizes and generated a "ship-track".
