Clouds Intro  

Posted by y. 源

If you have been following my blog, I am sure you have noticed that I have not been updating my blog for quite sometime already. Everyday is pretty much the same. You know, like wake up at 6.55am, breakfast at 7.20am, parade at 750am, class starts at 8.15am, lunch at 12.30pm, class resumes at 1.45pm, class ends at 5.00pm, online at crewroom until 7.00pm, dinner at 7.15pm, bath at 7.30pm, revision at 8.00pm, and finally sleep at 11.00pm.


Anyway, since today I am so bloody free and nothing to do, I shall share with you what I learned yesterday in Meteorology Class. Don't worry. I won't bore you with scientific terms. I will use layman terms here. =D

Topic: Clouds.

Clouds form due to a process called condensation, which water vapour in the air changes into the form of liquid known as water droplets. In this process, latent heat is released into the atmosphere. Whenever you order an iced drink, I am sure you have noticed water starts to form around the glass after some time, right? That's what we term as condensation.

Now, do you know that the air surrounding us contains water vapour? There are two types of air: Dry air and Saturated air. Dry air does not mean the air is totally dry! Air will never be totally dry as it will have some water vapour content in it no matter what. Saturated air means the parcel of air is full of water vapour.

The ability of a parcel of air to hold water vapour is dependent upon its temperature. The higher the temperature, the better is its abililty to hold water vapour. Dew point is the temperature for the water vapour to condense into water.


So far so good??


For the next post, it will be about the types of clouds in the sky. =D
