Low-level 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 are very low to the ground. These clouds play a crucial role in the Earth's weather system. They help regulate temperature by trapping heat and can influence local climates. Low-level clouds are also important for the water cycle, as they contribute to rainfall and provide moisture to the atmosphere.
