Formation of rain in warm ice-free clouds involves diffusional and collisional growth of cloud droplets and drizzle/rain drops. These processes are traditionally referred to as the warm-rain processes (in contrast to precipitation formation processes involving ice phase). Turbulence is often argued to play a significant role in warm-rain processes through affecting the diffusional growth of cloud droplets (and thus leading to the broadening of the droplet spectrum, an aspectimportant for the onset of gravitational collisions) or growth through the collision/coalescence. This presentation will introduce the cloud physics context for the particle in turbulence problem and provide a brief overview of recent observational and modeling studies concerning the role of turbulence in warm-rain processes.
