dark clouds

Dark clouds are dense collections of water droplets or ice crystals suspended in the atmosphere, appearing black or gray because they block sunlight from passing through. They often form when warm, moist air rises and cools, causing water vapor to condense. These clouds are commonly associated with weather changes like rain, storms, or snow, as they indicate a large amount of moisture and unstable atmospheric conditions. Their darkness is due to their thickness and the amount of light they absorb and block, signaling that precipitation may be imminent.
