the Clouds Wind

Definition

A tag is a hydrometeor consisting and in a visible mass of crystals formed snow or microscopic water droplets suspended s spades in the atmosphere. The n UBEs scatter all visible light and therefore appear white. However, sometimes d emasiado ensas od thick as to light the cross, and onces ent look gray or even black. Clouds are water droplets on co atmospheric dust. Then depending on some factors TAS their goti can become rain, hail or snow.

How is formed?

Clouds man for the air cooling. This causes the condensation tion of water vapor , invisible droplets or ice particles visible. The particles are so p MALL argue that vertical currents in the air mild.

differences between cloud formations are due, in part, the TES different condensation temperatures. When it occurs at temperatures below freezing, the clouds usually consist of ice crystals that form in warmer air usually contains droplets of a guide.

Air movement associated with the development of l as clouds also affects ion Formac. Clouds are created in air at rest tend to occur in layers or strata, while those formed from strong winds or air currents v Vertical orientation have great vertical development.

Types

There are several kinds of clouds, which can be classified into three groups: high clouds, cloud s middle and low clouds.

Partly cloudy

Cirrus, clouds are white, transparent and without internal shadows that look or fil lar cones risks and thin. These filaments may have regular distribution fo rma of parallel lines, whether straight or winding. Ocasionalmen filaments will have a muddled way. The overall appearance is as if the sky had been cubi Erto to strokes. When cirrus clouds invade the sky can be estimated

time, with decrease of temperature.

Cirrocumulus : They form a nearly continuous layer that presents the appearance of a surface with a Rruga rounded thin and small pieces of cotton. These clouds are completely white and have no ombras s . When the sky is covered with Cir

rocúmulos they say that it is mackerel. The Cirrocumulus frequently appear together with cirrus and usually indicate a change in weather in the next 12 h. This type of clouds often precede storm.

cirrostratus :

have the appearance of a veil, being difficult to distinguish details structure, with occasional or

n striated across. Its edges are set and regular boundaries. Such clouds usually produce a halo in the sky around the sun or moon. The cirrostratus tend to happen with cirrus and prelude to the arrival of bad weather, storm or warm fronts.

middle clouds

Altocumulus: They look like flakes of medium size and structure irregular, with shades between flakes. present as ripples or ridges wide

at the bottom. The Al

tocúmulos usually precede the bad time produced by rains or storms.

altostratus : Thin layers

of dense clouds in some areas. In most cases you can view

ar the sun through the cloud layer. The appearance is
altostratus that of a uniform layer of n UBEs with irregular patches. L usually portend altostratus fine and persistent Luvia with decrease of temperature.

Low clouds

Nimbostratos : They look like a regular layer of dark gray with various g

Rados opacity. With some frequency

trend is possible to observe a slightly striatum corresponding to different degrees of opacity and color variations of gray. Are you

Stratocumulus : They have large undulations like elongated cylinders, may

xcept when they become Nimbostratos.

Strata: Has the appearance of a gray fog bank without being able to see a definite structure or regular. Patches have different

opacity and color variations of gray. During the fall and winter the layers can remain in heaven

throughout the day giving a sad look at the sky. During the spring and early summer appear overnight dispersed during the day, indicating good weather.

Clouds of vertical development

Clusters: They have great size with a massive appearance

markedly s when they are between the sun and the observer, ie, they are gray clouds. have a horizontal base and top large vertical protrusions that deform continuously, showing a cauliflower-like appearance of great size. Clusters correspond to good weather in low humidity and little vertical movement of air. In the event of a high humidity and strong updrafts, the clusters can acquire a large rise reaching storms and heavy downpours.

Cumulonimbus : Large, massive appearance with a very marked vertical development gives the impression of mountain cliffs and whose top may have the form of a mushroom

large, and that presents a smooth or slightly fibrous structure where there are different intensities of

gray or waxy. These clouds can have on top of ice crystals large. The nmubes Cumulonimbus are typical of severe thunderstorms produce hail can reach.
