CLOUDS

1.What are clouds?
Clouds are a lot of waterdrups or iceparts together. The waterdrups and iceparts created by condensation from water vapour. Clouds have different kinds of substance, they have:
• Rain
• Snow
• Hail
More about these subjects in chapter 5.
 

2. How created  clouds?
Water evaporated trought the sun, the sun heats the water. The water vapor rises. Atop, in the air, the water vapor cools down to waterdrups. The waterdrups are so light that they are float in the air. The floating waterdrups or iceparts clash to each other, so become the waterdrups bigger. Together, they form a cloud. A cloud exist from a lot of waterdrups and iceparts. There have to be a lot of collisions before a raindrop forms.
You can clouds classified at base from their shape and height. They have difficult name’s. Look at the cloud map. You can use the cloud map to determine which cloud you see and what kind of weather it’s gonna be.
       
3. Cloudtype
Clouds become classified in low, midhigh and high  overcast.
In The Netherlands there are clouds they come to a height off 13,5 kilometer. And in the tropics, the clouds come to a height off 18 kilometer!
You can also see on the picture above here;
• A cloud is a low cloud when he is between the 0 to 2 kilometer.
• He’s midhigh if the cloud is from 2 to 6 kilometer.
• And a cloud is a high cloud if the cloud is higher than 6 kilometer.
​

4. Cloud cover
The cloud cover is how much cloud are in the air. If there are a lot of clouds that covering the air, there come’s almost no sun by the tree. The effects of that is that our tree not grows fast. If the sun shine’s always, and there is almost no cloud covering the air, our tree have a lot of sun. The effects of this, is that our tree dries out.

 

5. Rainfall
Not everywere on earth falls the same rainfall. In the tropics there falls a lot more rain. Also in countries that are close to the sea, there falls more rain.
The quantity rain is measured in millimeter whit a rain meter. Look at the rain meter right next from here.
• Snow,
Snow is a kind of rainfall. But instead of waterdrups, there falls little icecristalls. Here in The Netherlands, there falls mediated 30 days snow in one year. But this is not always so, there are nough years that we had no snow here in The Netherlands.
Snow created by water vapour. The water vapour freezes to icecristalls. The temperature have to be 5 to 20 C below 0.
• Rain,
Rain is also a kind of rainfall, rain is also called heavenwater. You need clouds to get rain, clouds exist from waterdrups, they become a cloud trought condensation. The clouds have to be bigger and more filled up whit rain drups, if the clouds is filled up enough, than it can start rain.
• Hail
Hail is a kind of rainfall, hail are frozen waterdrups. Hail are big (or small) iceballs. Hail is created by little icecristalls. When little icecristalls come betweenbig  layers filled up whit supercooled waterdrups. The 2 layers are kind of a cloud, in the first layer there are icecristals, in the second layer are supercooled almost frozen waterdrups. Trought the movement down and up from the air, the two layers are clashing to each other. The icecristalls and the supercooled waterdrups clashing to each other, trought this there created hail.
• Fog,
Fog are little waterdrup, the drups float in the air. The effect of fog is that your sight is smaller, you can’t see everything. Fog is created by cooldown from air or trought a admixture from cold and warm air.

​At a day, it’ rains 20 mm. That means that there everywere a layer of water from 20 mm (2 centimeter) in fallen, also in the rain meter.
