Today we learnt something new called FRONTAL RAIN. As Ms Lin explained earlier, frontal rain happens when there is a region of warm air and another region of cold air. There are two types of frontal rain.
1. When cold air sinks, it forces the warm air to rise and condense. A cold front is therefore formed and heavy downpours occur.
2. When warm air rises due to a region of cold air hindering it's path, a warm front is formed.
We also touched a little on climate change today, and we learnt that the difference between weather and climate is the time frame of the two. Climate is defined by a period of about 30 years or more while weather is on a short term basis.
We learnt that precipitation and temperature are two very important things to take note when describing the weather. Also, we were taught how to describe CLIMOGRAPHS. There are two main points to take note of when describing climographs:
1. Temperature (i.e. range, peak, average)
2. Rainfall (i.e. patterns, range[how wet])
Please take note as well that it is safer to describe Singapore as having HIGH RAINFALL.
For a sample of how to describe Climographs, you may refer to the description of Singapore's Climograph in the notes handed out today. (:
'KAHENG(:
So until now we have learnt 3 types of rain, which is differed by the way the air rises :) And among the 3 types, they can be combined to make different types of rain. It's so fun!!!!!!!!!!!!!
ReplyDeleteThanks Kah Eng!
Next lesson is my turn to write on the blog already... See ya! :)
I like this lesson because I like rain~haha~
ReplyDeleteI think we also have learnt something else in this lesson such as the process generating orographic rainfall-the stable forced uplift and the unstable free uplift and otherwise.
Ya~I'm so intersted in this lesson~ :)
