Q:

What are dark rain clouds called?

A:

Dark rain clouds are called stratus clouds. They are rainy, dense, dark or snowy clouds that sometimes appear as white cottony clumps surrounded by blue sky.

Full Answer

The word stratus is derived from a Latin word meaning “layers.” These are low clouds that look like shapeless gray sheets extending in every direction. Stratus clouds are approximately 1,093.6 yards thick and can spread to over 621.5 miles wide. These rain clouds build when moist, warm air rises above colder air; they are gloomy and dark and related to drizzle and rain. When stratus clouds rest on the sea or the ground, they are known as fog.

  • Q:

    How can cumulonimbus clouds produce rain and hail?

    A:

    Cumulonimbus clouds, also known as thunderheads, release hail and rain in conjunction with updrafts. Ice crystals ride such updrafts into the air and then fall through the clouds, collecting water droplets as they drop. Once water droplets freeze onto ice crystals, hailstones are created. Cumulonimbus clouds release rain when they have reached their moisture saturation point.

  • Q:

    How clouds are made?

    A:

    Clouds form when warm, moist air rises into the upper atmosphere, where the cooler temperatures cause the water to condense. Depending on the altitude, clouds may be made up of water droplets or ice crystals, and these often form around floating motes of dust or other particles. When too much moisture condenses, the droplets or crystals become too heavy to stay aloft, falling as snow or rain.

  • Q:

    How do clouds float?

    A:

    Clouds float because the water droplets that comprise them are so incredibly tiny that they do not fall very fast. As clouds frequently occur in places that are experiencing updrafts, the force of the air pushing them up offsets the weight of the water droplets. In a cloud of typical size, the water droplets often weigh approximately 1/1000th as much as the air that containing them does.

  • Q:

    How much do clouds weigh?

    A:

    Cumulus clouds, which are generally the largest, can weigh in excess of 1 million pounds. This figure comes from a relatively simple density calculation involving the average volume of the cloud times the known density of water within it.
