Gases move from high-pressure areas to low-pressure areas. And the enlarge the difference in between the pressures, the faster the waiting will move from the high come the short pressure. That rush of wait is the wind we experience.

Wind is a component of weather we endure all the time, but why walk it in reality happen? The air will certainly be still one day, and also the next, an effective gusts that wind deserve to knock down trees. What is walk on here?

The main reason of wind is a small surprising. It’s in reality temperature. An ext specifically, it’s differences in temperature between different areas.

How would temperature differences make the wind blow?

The gases that comprise our environment do exciting things as the temperatures change. Once gases heat up, the atoms and also molecules move faster, spread out, and rise. That’s why steam coming turn off a pot of boil water constantly goes upward. As soon as air is colder, the gases get slower and also closer together. Chillier air sinks.


The sunlight warms increase the air, but it does for this reason unevenly. Since the sun hits different parts of the earth at various angles, and because earth has oceans, mountains, and also other features, some locations are warmer 보다 others. Due to the fact that of this, we obtain pockets of warmth air and cold air.

Different temperatures lead to different pressures

Since gases behave differently at different temperatures, that method you additionally get pockets with high pressure and pockets v low pressure. In areas of high pressure, the gases in the wait are more crowded. In low press zones, the gases space a little more spread out.

You can think that the heat air would result in a greater pressure area, however actually opposing is true. Since warm waiting rises, it leaves behind one area the low pressure behind it.


Here come the wind!

Now we’re obtaining to the part where wind happens. Gases move from high-pressure areas to low-pressure areas. and the larger the difference between the pressures, the much faster the waiting will relocate from the high come the low pressure. The rush of waiting is the wind us experience.


But why go the air move at all?

You can be wondering why the waiting would relocate from high press to low push in the first place. This is something that happens in nature all the time: things always try to even out. It’s dubbed diffusion.

Even human being do it! When civilization get ~ above a bus, do they every sit on the exact same side the the bus first? do strangers sit next to each other as soon as there room plenty of open up seats? No way. People want to spread out out as lot as possible.

Next time you feeling the wind blow, think around where that going, and what temperatures and also pressures are leading to it to execute that.

GOES-16 the town hall Wind

In 2016, the first satellite in the GOES-R series, GOES-16, launched into orbit. This will offer scientists new ways to save an eye on wind.

The advanced Baseline Imager (ABI) top top the GOES-16 satellite deserve to do all kinds of things. It tracks clouds, temperature changes, operation of water, fire, smoke, and wind. It takes satellite imagery to watch atmospheric motion and also improve our ability to forecast weather.
