Blow me Away in the Wind...

Wind



Days are shorter;
nights are longer,
Few stars here and there...
Branches breaking off, flying around looking, like wizard's broom; with their leaf buddies.
What are you doing wind?
As the wind touches me, the goose bumps pops out to protect me; but it fails. My hair flying away in the wind. It felt like the lonely wind was going to disappear me with it, just like how it disappeared the moon.
The moon was missing!
It almost felt like a tornado. But it wasn't as bad.
It was crazy outside. I didn't stay out there for much. That Wind's noise scared me. It almost sound like the wind was communicating. But does it?
I mean what is wind?
What causes wind?

Wind

Wind is air in motion. It is produced by the uneven heating of the earth's surface by the sun. Since the earth's surface is made of various land and water formations, it absorbs the sun's radiation unevenly. Two factors are necessary to specify wind:
speed and,
direction.

What really causes the wind to blow is, when the sun warms the earth's surface, the atmosphere warms too. So, some parts of the earth receives direct rays from the sun all year and are always warm.
Warm air, which weighs less than cold air, rises. So, then the cool air moves in and replaces the rising warm air. And this movement of air is what makes the wind to blow.

In the article How Stuff Works?  It said that "In mountainous areas, winds tend to blow uphill during the day because the mountainside is heated more than the valley below it. At night, when the mountainside cools, the wind blows downhill. In summer, breezes tend to blow from oceans or large lakes to the warmer land during the day. They blow from the land at night, when the land cools." (http://science.howstuffworks.com/dictionary/meteorological-terms/wind-info3.htm)

So I found this two different breeze. The two different cycle of wind/breeze:

We might hate wind and think it's useless and all. But in reality it is really useful. Wind is the fastest growing source of electricity in the world. It's often one of the least expensive forms of renewable power available. Some experts say it can sometimes be the cheapest form of any kind of power.

I never knew this but, wind has many different names.
On the Weather Wiz Kids website it gave me a list of the names:
"Chinook-(westerly wind off the eastern side of the Rocky Mountains)
Santa Ana-(easterly towards Southern California )
Scirocco
-(southerly from North Africa to southern Europe)

Mistral-(northwesterly from central France to Mediterranean)
Marin-(southeasterly from Mediterranean to France)
Bora-(northeasterly from eastern Europe to Italy)    
Gregale-(northeasterly from Greece)
Etesian-(northwesterly from Greece)
Libeccio-(southwesterly towards Italy)"

WindvaneThe Wind ChartWindvane
This is a chart called "Beaufort Scale" it is where the empirical measure for the wind power is provided. This gives all the information about wind's speed, it's description, and it's conditions as well. This scale was created by a British naval commander "Sir Francis Beaufort" in 1806.

 Trees uprooted. Considerable structural damage

  1. I love the descriptions of the different kinds of wind. It seems funny that they're that specific, but I guess weather people take their stuff as seriously as us language people.

  2. I didn't know there was different types of wind. Interesting though, I love the pictures really gave me an idea about how the wind works.

  4. I never really cared about wind to even think about it except that it feels really good in blazing summer days. I like how you give us information on how wind occurs. Another fact that I liked from your blog is that you mention how wind can provide energy for humanity.To top it all off you even gave us a straightforward picture that really helps me understand how wind are made.
