Which type of precipitation is formed by convection in cumulonimbus clouds?
Cumulonimbus storm cells can produce torrential rain of a convective nature (often in the form of a rain shaft) and flash flooding, as well as straight-line winds. Most storm cells die after about 20 minutes, when the precipitation causes more downdraft than updraft, causing the energy to dissipate.
What could cause a cumulonimbus cloud to release rain?
How do cumulonimbus clouds form? Cumulonimbus clouds are born through convection, often growing from small cumulus clouds over a hot surface. They can also form along cold fronts as a result of forced convection, where milder air is forced to rise over the incoming cold air.
How does a cumulonimbus cloud form?
Like many clouds, the cumulonimbus develops when warm air rises from the surface of the earth. As the warm air rises, it cools, and water vapor condenses into minute cloud droplets. In a thunderstorm, the updraft of warm air is rapid, and the cloud builds up quickly.
What kind of rain does a cumulonimbus cloud produce?
The cumulonimbus cloud, or thunderstorm, is a convective cloud or cloud system that produces rainfall and lightning. It often produces large hail, severe wind gusts, tornadoes, and heavy rainfall. Many regions of the earth depend almost totally upon cumulonimbus clouds for rainfall.
How are droplets in a cloud related to precipitation?
One theory explaining how the behavior of individual droplets in a cloud leads to the formation of precipitation is the collision-coalescence process. Droplets suspended in the air will interact with each other, either by colliding and bouncing off each other or by combining to form a larger droplet.
How are the particles in a Cloud pulled down to Earth?
As tiny water particles that make up the cloud group together to form droplets of rain, they are pulled down to earth by the force of gravity. The droplets would normally evaporate below the condensation level, but strong updrafts buffer the falling droplets, and can keep them aloft much longer than they would otherwise.
How are cumulus clouds composed of liquid water?
Cumulus clouds are, with rare exceptions discussed below, composed solely of droplets. They have the highest liquid water concentrations of any clouds in their upper portions where the moist air has been lifted the highest. To be a purely cumulus cloud, very few precipitation-sized particles are in them, though they may be imminent.
