Atmospheric Science Clouds And Precipitation (1986)

Discusses the various forms of water in the atmosphere, emphasizing the processes of evaporation, condensation, and cloud formation. Water vapor primarily originates from warm tropical oceans, where higher temperatures increase evaporation rates. The formation of clouds and fog occurs when moist air cools, reaching the dew point temperature, which is influenced by the amount of water vapor present. Cloud droplets are tiny spheres of water that can form and disappear quickly, aided by condensation nuclei like dust and salt particles. The interaction of cloud droplets leads to raindrop formation, which can occur through collision and coalescence or through ice crystal processes in colder conditions. Mountains can significantly affect precipitation patterns, leading to rain on one side and clear conditions on the other. Additionally, cumulonimbus clouds, or thunderheads, are formed through convection processes and can produce severe weather. Atmospheric scientists study these clouds using specialized equipment to understand their dynamics better. We digitized and uploaded this film from the A/V Geeks 16mm Archive.
