Cloud formation is the process by which water vapor in the atmosphere condenses into visible cloud droplets. This process is influenced by a variety of factors, including temperature, humidity, air pressure, and the presence of condensation nuclei. Cloud formation plays a crucial role in the Earth's climate system, as clouds affect the distribution of solar radiation, precipitation patterns, and atmospheric circulation. Research in this area seeks to understand the processes governing cloud formation, as well as the role of clouds in climate change and weather forecasting. This research involves a combination of field observations, laboratory experiments, and computer modeling.
