What are isotherms, isobars, front, prevailing    wind, doldrums, and cirrus?

Isobars and isotherms are both lines on a weather map  that represent the patterns of pressure and
temperature.
They show how the temperatures and pressure are changing over space and so help describe
the large-scale weather patterns across a region in the map.

Front. 

Prevailing winds are winds that blow from a single direction over a specific area of the earth.
Areas where prevailing winds meet are called convergence zones.

Doldrums are located a little north of the equator,
but the effects can be felt from way over  5 degrees north of the equator to 5 degrees south of it.
The trade winds border the Doldrums both to the north and south.
Then there are the prevailing westerlies in the higher latitudes and the polar easterlies near both poles.

Cirrus clouds form from the rise of dry air,
making the small quantity of water vapour in the air which undertakes deposition into ice
(to change from a gas directly into a solid).
Cirrus is made up completely of ice crystals,
which provides their white colour and form in a wide range of shapes and sizes.

How Snow Is Formed

How Snow And Rain Is Formed

Snow is created when the water vapor in the air freezes before it can turn into water;
this usually happens when it reaches 32 degrees fahrenheit.
That means it is allowing the raindrops to form into crystals as the rain droplet comes from the cloud and gets
bigger and bigger because the vapor condensates it.  Eventually the droplet
gets so cold they freeze into a microscopic ice crystal which is known as snow.

 

Light bounces off the clouds and the atmosphere particles get shattered. 

This leaves longer light wavelengths than we see causing snow to look white. Snow also helps 
cover the Earth's surface and once it melts it helps form rivers, lakes and reservoirs.
Rain
is formed when  droplets of water that fall from clouds. Heat from the Sun turns moisture (water) from plants and leaves, as well as oceans, lakes, and rivers, into water vapour (gas), which disappears into the air. This vapour rises, cools, and changes into tiny water droplets, which form clouds. 

In conclusion I think that this was a very interesting thing to research.

I did not know this much about snow and how it was created.
Now I have more knowledge around this topic.

Vexx Art

In visual arts we had to create a picture from vexx using his video to draw.
Here is what I made. WALT: Develop ideas by developing and revisiting visual ideas, in response to examples we have seen, and ideas that we can think of for ourselves.
