Low clouds are clouds that form at altitudes below 2,000 meters (about 6,500 feet). They include types such as stratus, stratocumulus, and nimbostratus. These clouds often appear gray and can cover the sky, leading to overcast conditions. They are typically associated with light precipitation and can create fog when they touch the ground. Low clouds play a significant role in the Earth's weather system. They can trap heat, affecting local temperatures, and contribute to the water cycle by releasing moisture. Their presence can also influence visibility, making driving conditions more challenging in areas with dense fog or low cloud cover.
