Turbulent convection between a warm bottom surface and a cold top surface leads to a supersaturated environment when those surfaces are wet. A cloud forms when aerosol particles are injected. Here the turbulent cloud is visualized with a green laser light sheet. (The red beams are for measuring droplet diameter and number density.)
