What are cloud droplets?

Cloud droplets are tiny water droplets that form in the atmosphere when water vapor condenses around small particles, such as dust or salt, known as cloud condensation nuclei. These droplets are typically about 10 to 15 micrometers in diameter and can coalesce to form larger droplets, eventually leading to precipitation. They play a crucial role in the Earth's weather and climate systems by influencing cloud formation, reflectivity, and the hydrological cycle.
