What type of cloud is associated with hail?
cumulonimbus cloud
What causes ripples in clouds?
The ripples form when humid air at the far-flung edges of the storm system pushes past clear, cool air high in the sky. It’s the resistance of the cool air to this motion that causes the ripples. Ridges of cloud form where water vapour cools and condenses, while troughs of space form where it warms and re-evaporates.
What causes straight line clouds?
Rising warm air cools gradually as it ascends into the atmosphere. When moisture in the warm air mass cools and condenses, it forms clouds. Cloud streets typically form fairly straight lines over large flat areas such as the ocean.
What clouds are flat white and layered?
Cumulus clouds look like fluffy, white cotton balls in the sky. They are beautiful in sunsets, and their varying sizes and shapes can make them fun to observe! Stratus cloud often look like thin, white sheets covering the whole sky. Since they are so thin, they seldom produce much rain or snow.
How can you identify a cumulonimbus cloud?
Cumulonimbus clouds are menacing looking multi-level clouds, extending high into the sky in towers or plumes. More commonly known as thunderclouds, cumulonimbus is the only cloud type that can produce hail, thunder and lightning.
How do you identify a cumulonimbus cloud?
The character of the precipitation may help to distinguish Cumulonimbus from Nimbostratus. If the precipitation is of the showery type, or if it is accompanied by lightning, thunder or hail, the cloud is Cumulonimbus. Certain Cumulonimbus clouds appear nearly identical with Cumulus congestus.
What is the color of a cumulonimbus cloud?
They range in color from dark gray to light gray and can appear in rows, patches, or as rounded masses with breaks of clear sky in between. Rain or snow rarely fall from these clouds and they are different from altocumulus clouds since their individual elements are larger than those of their altocumulus counterparts.
How does a cirrus cloud look like?
Cirrus clouds are made of ice crystals and look like long, thin, wispy white streamers high in the sky. They are commonly known as “mare’s tails” because they are shaped like the tail of a horse. Cirrus clouds are often seen during fair weather.
Why are cirrus clouds so thin?
Cirrus are thin, whispy clouds composed of ice crystals that originate from the freezing of supercooled water droplets and exist where temperatures are below -38 degrees Celsius. The change in wind with height and how quickly these ice crystals actually fall determine the shapes and sizes the fall streaks attain.
What causes cirrus clouds to form?
Cirrus clouds form from the ascent of dry air, making the small quantity of water vapour in the air undergo deposition into ice (to change from a gas directly into a solid). Cirrus is made up completely of ice crystals, which provides their white colour and form in a wide range of shapes and sizes.
