How Does Air Pressure And Wind Effect Animals

Why Does Wind Blow?

The Short Reply:

Gases move from high-pressure level areas to low-pressure areas. And the bigger the deviation between the pressures, the faster the air will move from the high to the low force per unit area. That rush of air is the wind we experience.

Wind is a function of atmospheric condition we experience all the time, but why does it actually happen? The air will exist nonetheless one twenty-four hour period, and the next, powerful gusts of current of air tin can knock down copse. What is going on hither?

The main crusade of current of air is a little surprising. Information technology's really temperature. More specifically, information technology'south differences in temperature between different areas.

How would temperature differences brand the current of air blow?

The gases that make upwardly our atmosphere do interesting things as the temperatures modify. When gases warm up, the atoms and molecules move faster, spread out, and rise. That's why steam coming off a pot of boiling water e'er goes upward. When air is colder, the gases get slower and closer together. Colder air sinks.

The lord's day warms up the air, simply information technology does then unevenly. Because the dominicus hits different parts of the Earth at different angles, and because Earth has oceans, mountains, and other features, some places are warmer than others. Because of this, we get pockets of warm air and common cold air.

Different temperatures lead to different pressures

Since gases behave differently at different temperatures, that means yous also go pockets with high pressure and pockets with low pressure level. In areas of high pressure, the gases in the air are more crowded. In low force per unit area zones, the gases are a little more than spread out.

You might think that the warm air would lead to a higher pressure level area, only actually the opposite is truthful. Because warm air rises, it leaves behind an area of low pressure behind it.

Here comes the air current!

Now nosotros're getting to the part where wind happens. Gases move from high-pressure areas to depression-pressure level areas. And the bigger the deviation between the pressures, the faster the air will move from the loftier to the low force per unit area. That rush of air is the air current we feel.

Only why does the air move at all?

You lot might be wondering why the air would move from high pressure to depression pressure level in the first place. This is something that happens in nature all the time: things e'er attempt to even out. Information technology's called improvidence.

Even people practise it! When people get onto a bus, do they all sit on the same side of the coach kickoff? Do strangers sit next to each other when there are plenty of open seats? No style. People want to spread out as much as possible.

Next time you lot feel the wind blow, think most where it's going, and what temperatures and pressures are causing it to do that.
