Cloud physics Terrestrial clouds can be found throughout most of the homospherewhich includes the tropospherestratosphereand mesosphere. The cloud base takes on a darker grey coloration and the top commonly resembles a cauliflower.
Cumulonimbus clouds can form in unstable airmass conditions, but tend to be more concentrated and intense when they are associated with unstable cold fronts.
Subreddits Below is a table of subreddits that you might want to check out! They occur in highly unstable air  and often have fuzzy outlines at the upper parts of the clouds that sometimes include anvil tops.
Atmospheric convection Towering vertical cumulus congestus embedded within a layer of cumulus mediocris.
Within these layers of the atmosphereair can become saturated as a result of being cooled to its dew point or by having moisture added from an adjacent source.
Stratocumuliform and stratiform clouds in the high altitude range carry the prefix cirro- yielding the respective genus names cirrocumulus Cc and cirrostratus Cs.
Increasing airmass instability can cause free-convective cumulus to grow very tall to the extent that the vertical height from base to top is greater than the base-width of the cloud.
Lamarck had worked independently on cloud classification the same year and had come up with a different naming scheme that failed to make an impression even in his home country of France because it used unusual French names for cloud types.
Cirriform[ edit ] Cirriform clouds are generally of the genus cirrus and have the appearance of detached or semi-merged filaments. They often form along a high altitude jetstream  and at the very leading edge of a frontal or low-pressure disturbance where they may merge into cirrostratus.
These are small detached fair-weather cumuliform clouds that have nearly horizontal bases and flattened tops, and do not produce rain showers. When limited-resolution satellite images of high clouds are analysed without supporting data from direct human observations, it becomes impossible to distinguish between individual forms or genus types, which are then collectively identified as high-type or informally as cirrus-type even though not all high clouds are of the cirrus form or genus.

Time-lapse video of clouds at sunset in Japan Etymology and history of cloud science and nomenclature[ edit ] Etymology[ edit ] The origin of the term cloud can be found in the old English clud or clod, meaning a hill or a mass of rock. A license plate is not PI.
The stratiformis species normally occur in extensive sheets or in smaller patches where there is only minimal convective activity. Feel free to post your own, but please read the rules first see belowand note that we are not a catch-all for general images of screenshots, comics, etc.

Although genus types with vertical extent are often informally considered a single group,  the International Civil Aviation Organization ICAO distinguishes towering vertical clouds more formally as a separate group or sub-group. The sun and moon are visible in clear outline.

Granite Vanity Top in Blue Pearl with White Basin /8 Price: $ In meteorology, a cloud is an aerosol consisting of a visible mass of minute liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body.
Water or various other chemicals may compose the droplets and crystals. On Earth, clouds are formed as a result of saturation of the air when it is cooled to its dew point. A small thermal has popped off, creating the thermal cumulus, which are low level clouds.
Behind, way in the distance at high altitude is some cirrus, that due to the photo, looks like it's coming out of the cumulus.
