These clouds exhibit less strato (flat and uniform) characteristics and more cumulo (this means fluffier). They usually indicate localized areas of rising, moist air with clear areas between them of sinking, drier air. In the morning especially, these clouds indicate instability in the air, whic...
Humid air rising in the cores of cumulus clouds cools as it rises. The cooling causes the condensation and growth of water droplets to form the cloud, and the droplets supercool when the temperature falls below the freezing point. These water droplets are very small, and rise in the updraft...
They usually indicate localized areas of rising, moist air with clear areas between them of sinking, drier air. In the morning especially, these clouds indicate instability in the air, which could then be released into deep convection by the afternoon or evening. Photo: Wikimedia Commons CC-BY...
If the upward motions in the eddies result in the top of the eddy rising above the lifting condensation level, then small cloud elements form. Cloud-top radiative cooling then promotes further turbulent mixing and condensation. The depth of the stratocumulus cloud-top mixed layer is typically ...
They are at least as tall as they are wide and form on sunny days from pockets of rising air. Their constantly changing outlines are fun to watch because they can take the shapes of almost anything, including animals and faces. Cumulus clouds usually signal fair weather. If they build into...
Now imagine the ball is on top of a hill. Even a little push will make it roll down the hill. A pocket of air pushed up in an unstable atmosphere keeps rising. Here's when clouds can form and storms can happen. The ball will stay where you push it if it's on flat ground. Like...
A wall cloud is a cloud that islowered from a thunderstorm, forming when rapidly rising air causes lower pressure below the storm's main updraft. ... Wall clouds that rotate are a warning sign of very violent thunderstorms. They can be an indication that a tornado will touch down within ...
Thunderstorms can also form along the boundary, or front, between air masses of different temperatures. In this case, the denser cool air displaces the warmer and forces it to rise. The greater the contrast in temperature and moisture across the frontal boundary, the greater the instability of...
And lastly, clouds will form where air masses collide; two different air masses can’t mix unless they are very similar in temperature and moisture content. If a cold, dry air mass pushes into an air mass that is warm and moist, the warmer air is forced upward, rapidly producing clouds ...
(redirected fromCumulus Clouds) Dictionary Thesaurus [′kyü·myə·ləs ‚klau̇d] (meteorology) A principal type of cloud in the form of individual, detached elements which are generally dense and possess sharp nonfibrous outlines; these elements develop vertically, appearing as rising moun...
