Description
Evaporation of cloud droplets accelerates when turbulence mixes dry air into the cloud, affecting droplet-size distributions in atmospheric clouds. The challenge is to model local correlations between droplet numbers, sizes, and supersaturation. These correlations are important because they determine supersaturation fluctuations along droplet paths, which in turn affect how droplets grow or shrink. We derived a statistical model that accounts for these correlations. Its predictions are in quantitative agreement with results of direct numerical simulations, and it explains the key mechanisms at play.
