👉 Precipitation fluids, also known as cloud droplets or fog droplets, are tiny water droplets that form within clouds through the condensation of water vapor. These droplets typically range in size from 0.1 to 10 micrometers and are created when water vapor in the atmosphere cools and condenses around aerosol particles, like dust or salt. The growth of these droplets occurs as more water vapor condenses onto existing droplets, eventually leading to the formation of larger droplets that can become heavy enough to fall as precipitation, such as rain, snow, sleet, or hail, depending on atmospheric conditions.
