a

Identifying clouds - Cumulus, Cirrus and Stratus

hello everybody in this video we're

going to be looking at clouds and

specifically how they are formed and

also to be able to identify the

different types of clouds

so although clouds look like they might

be gas they are in fact not there are

little tiny droplets of water that are

found in our atmosphere clouds are

formed when the Sun hits any surface

body of water like the sea a lake or a

river this evaporates and the hot air

will gradually cause this evaporated

water vapor to rise up within the

atmosphere as air rises it begins to

cool because typically we lose about one

degree centigrade every hundred meters

we gain in elevation the water vapor

begins to cool and then condenses on the

tiny little particles floating in the

air

these can be pollen dust or even

pollution particles these particles are

could condensation nuclei and they

provide the surface for the water vapor

to condense onto when enough water

vapour has condensed onto a surface of a

particle tiny Kile droplets are formed

now either typically very light but

because there are so many of them

together then in total they can weigh

hundreds of tons clouds float because

firstly the particles are very widely

spread and secondly because of warm air

that is still rising underneath the

clouds keeps them afloat when a high

concentration of cloud droplets condense

onto the surface particles this can then

become very very heavy and heavy enough

for it to fall as rain

a typical cloud related question that I

hear all the time is why are clouds

white well this is because light hits of

water droplets in all the colors of the

rainbow but the clouds and scattered

this light and to earth therefore it

appears like white light

gray clouds on the other hand have this

color because they are so thick with

water droplets that sunlight cannot pass

through them giving them the gray

ominous looking color now if you look

into the sky you may see different types

of clouds

however these clouds fall into three

main categories or types firstly we have

stratus clouds these are spread out like

blankets to cover most of the sky they

had tend to have a uniform color like a

white or a grey and typical typically

there is a little or no precipitation

from this type of cloud they are low

clouds and typically sit below 2,000

meters in the atmosphere the second type

of cloud we have are cumulus clouds

these are the stereotypical clouds of

the sky and when you imagine clouds you

usually think of these they normally

form from fluffy individually shaped

clouds with a flat bottom or base these

clouds also set quite low in the

atmosphere at about 2,000 meters and

they are the most common cloud type they

usually indicate clear weather but on

occasion can bring short showers of rain

lastly we have a type of cloud coat

Cirrus this actually comes from an old

Latin word meaning curl of hair

these clouds form very high in the

atmosphere about 7,000 meters and they

are wispy white in color they are so

high in the atmosphere that they are

made up of ice crystals and the sunlight

passes right through them so they're

normally quite hard to see they usually

indicate fair weather with no

precipitation when describing clouds we

often make combination of cloud

characteristics and for example if we

add the word Alto before three

previously mentioned cloud types were

indicating that this cloud is now found

in the middle part of our atmosphere for

example and now to cumulus cloud we

found around three

and meters and will typically be a bit

smaller than the previous aforementioned

cumulus cloud another word we can

include with clouds is a word Nimbus

this is attached to a cloud that

produces rain snow hail or sleet for

example a cumulus Nimbus is a large grey

flat-bottomed cloud that sits low in our

atmosphere and from which you get large

storms here are some other combinations

we could have altocumulus which we've

described before ultra Stratus which is

a blanket covering cloud found in the

middle atmosphere cirrocumulus are very

high up fluffy clouds that are very hard

to see cirrostratus are very wispy

Highline clouds that cover the whole sky

and stratocumulus which your are your

typical winter clouds which are

low-lying and rolling and as we've

discussed before the most typical

combination of cloud name would include

the word Nimbus or Nimbo any cloud with

the word Nimbo such as cumulonimbus

would be a rain cloud and you will get

some form of precipitation from it

clouds pay a very important role in the

water cycle and without them it would be

impossible water evaporates from all

bodies of water it rises and begins to

cool it reaches the dew point and

condenses onto particles forming clouds

and then when these particles join

together and become too heavy they form

in the form of precipitation such as

rain or snow this is then repeated and

ensures that the water cycle continues

looking at clouds makes it very possible

for us to predict the weather

Serkis cumulus clouds normally bring

good weather altostratus clouds means

usually rain or snow and nimbostratus

clouds tend to be

a half-orc tend to have quite a high

chance of precipitation
