Anyway, here are the facts:
 |
| These clouds in the Cairngorms were probably Nimbus clouds as it was pretty rainy when I was there - still very beautiful though. |
- There is one main type of cloud that I haven't covered and that is the Nimbus Cloud. They can look a lot like Stratus Clouds but are different...
- ...Nimbus Clouds are rain bearing meaning they have so many water molecules in them that some of them merge to become rain drops.
- Over the last couple of posts I haven't really mentioned how they are formed. I have mentioned the water cycle in Cloud part 2 and that's basically how rain falls, so here's how clouds are formed:
- Clouds can be created in just a couple of minutes, to up to a few hours. Water vapour rises and cools, some of the vapour condenses into tiny dust particles. When millions of these come together, they create a cloud.
- The dust particle in these clouds are only 0.02 millimetres in diameter which is only five times smaller than the average thickness of a sheet of paper. Imagine how many of these you'd need to make one of those huge, Stratus clouds you can sometimes find.
- Two bad things about clouds are tornadoes and hurricanes. These disasters are created when warm air flows to a 'space' where there isn't as much warm air. This event sucks in more warm air which then rises creating a continuous up-flow.
- The air that surrounds the low pressure zone flows in a spiral, the clouds get sucked in and start spiralling around in a continuous circle. All of this gets repeated and the hurricane/tornado gets stronger and stronger.
- As I have said in a previous cloud post, clouds can be on other planets too so this means that there could be hurricanes on other planets, Turns out, there is! Here is a link to a National Geographic site that explains about a hurricane found in the North Pole of Saturn. Click here.
Here are some links to some more information:
