Which effect does increased aerosol concentration have on regional cloud formation?

💡 Explanation

When aerosol concentrations increase, cloud condensation nuclei increase, leading to smaller and more numerous cloud droplets because available water is distributed across more particles, reducing collision-coalescence efficiency. Therefore drop in collision rates occurs, rather than higher ice precipitation, radiative cooling, or droplet uniformity requiring lower particle counts.
