What causes altostratus clouds?
Altostratus is formed by the lifting of a large mostly stable air mass that causes invisible water vapor to condense into cloud. It can produce light precipitation often in the form of virga. If the precipitation increases in persistence and intensity the altostratus cloud may thicken into nimbostratus.
How much water is in a cumulus cloud?
A typical cumulus cloud carries about half-a-gram of water in each cubic metre — that’s the weight of a big garden pea. A big fat dark cumulonimbus cloud could carry up to six times as much water (say three grams of water per cubic metre).
What is the rarest cloud?
Kelvin Helmholtz Waves are perhaps the rarest cloud formation of all. Rumored to be the inspiration for Van Gogh’s masterpiece “Starry Night” they are incredibly distinctive. They are mainly associated with cirrus altocumulus and stratus clouds over 5 000m.
Does cumulus clouds produce rain?
Normally cumulus clouds produce little or no precipitation but they can grow into the precipitation-bearing congests or cumulonimbus clouds. Cumulus clouds can be formed from water vapour supercooled water droplets or ice crystals depending upon the ambient temperature.
Where Are Cumulus Clouds Found?
Cumulus clouds are a genus of free-convective low-level cloud along with the related limited-convective cloud stratocumulus. These clouds form from ground level to 2 000 metres (6 600 ft) at all latitudes.Cumulus clouds are a genus of free-convective low-level cloud along with the related limited-convective cloud stratocumulus.

What weather does altostratus clouds bring?
What weather is associated with altostratus clouds? Altostratus clouds often form ahead of a warm or occluded front. As the front passes the altostratus layer deepens and bulks out to become nimbostratus which produces rain or snow. As a result sighting it can usually indicate a change in the weather is on the way.

What are the characteristics of cumulonimbus clouds?
Cumulonimbus clouds are one of the most recognisable cloud types characterised by their threatening anvil-shaped tops and the torrential rain hail thunder and lightning that they often produce. They are the tallest clouds we see and can extend through the entire height of the troposphere.
Where are the ice crystals in a cumulonimbus cloud?
When the fibrosity of the upper portion of the cloud is fully apparent the cumulonimbus cloud has transitioned to a cumulonimbus capillatus (‘hairy’) in which most or all of its upper portion consists of ice crystals and snowflakes.
