Stratus clouds are low-level, grey, fog-like clouds that often encompass the entire sky. They are uniform, often forming low-hanging shelves which lead to overcast days with little to no precipitation. Stratus clouds do ... More » Science Weather & Tides Clouds

Cirrocumulus clouds are composed of supercooled water droplets and form through shallow convection within thin labile layers of air. These high-altitude clouds form between 16,600 and 30,000 feet. More » Science Weather & Tides Clouds

Cumulonimbus clouds form when warm, moisture-laden air travels upward and is cooled, condensing into a tall body of water droplets. Cumulonimbus clouds can reach up to 10 kilometers in height and take on a flat-topped ap... More » Science Weather & Tides Clouds

According to Met Office, clouds form when water vapor in the air condenses into tiny drops of water or ice crystals that then settle on dust particles in the atmosphere. Condensation happens when the air is saturated and... More » Science Weather & Tides Clouds
