What causes wind to blow?

In this video we explain the science behind wind.
Wind is air in motion, travelling between areas of different pressure. To understand what causes this motion; we first need to understand a bit about air pressure. When air heats up, the atoms and molecules within it move faster and spread out. It is this reaction to heat that causes warm air to expand and rise, In colder air the molecules move more slowly and are closer together, which makes the air sink. When heat from the sun reflects off the Earth surface, it warms the air above it - this air will rise, leaving areas of lower pressure. In contrast, areas of higher pressure occur where the cooler air is located. When there is a difference in air pressure between two areas, air moves from the high pressure area to low pressure area to equalise the pressure. The best example of how this causes wind is in coastal areas.
On sunny days, land warms up quicker than the sea, which reflects more of the sun’s rays. This creates a temperature contrast and, as the land heats up, it warms and expands the air above it. As this warm air expands, an area of low pressure is created over the land leaving relatively higher pressure over the sea. This pressure difference causes air to move from the sea to the land to equalise the pressure difference. That rush of air is the wind we experience. In this case, a sea breeze.

Thank you for making this video, it’s exactly what I needed to finally understand this

[@CTheRobot]

Lovely, I’d watched a video from elsewhere and didn’t quiiiiiite get it, but the sea breeze example was just what my brain needed! Thanks 🙌🏾

[@rodolfodumaliangiii7342]

The way on how you explain it is brillant.

Good. Now I understand wind, and so have the TOOLS STOP IT ONCE AND FOR ALL!!!! HAHAHAHA!!!!!!

[@foreverraining1522]

So why are there high winds in the winter? For example in NY or Chi, the sun doesn't provide that much heat in winter, so shouldn't the pressure be relatively the same? And where do sudden wind gusts come from?

[@ahmadferoz1401]

why does air pressure have to equalise, why cant one area just be low pressure and one be high pressure and co-exist as it is, is there an electromagnetic attraction that makes high pressure spaces move to the low pressure spaces?

[@muskets5718]

equilibrium my friend

[@mr.rachetphilanthrophist601]

Like concentration gradient result in mixing untill equillibrium. Same here follows for pressure gradient for wind movement and for both area's pressure to come at one and the samr equillibrium level.

[@rodjames8983]

If the sun is a long way away would the side the sun shines on the earth be high pressure and the other side low?

[@BigPurpleCarrot]

If the sun is a long way away why is day time warmer than night?

[@davebalmada]

Can climate change affect the strength and frequency of winds in coastal areas? I live in The Netherlands and I need to know if I'll have to prepare for stronger winds :(

[@mr.rachetphilanthrophist601]

In coastal areas due to moderating influence of oceans the diurnal tempreature difference and annual tempreature difference is less so there will be less chance of extreme climatic conditions near coastal areas. Except for may be floods and heavy rainfall nothing much affects coastal areas.

[@venkataramanavaddepalli8955]

Good

[@nicgreaves3484]

So why does the heat need to be absorbed by the earth and re emitted as opposed to just being heated up the first time?

[@jameslarkin4119]

It doesn’t need to be efficient it just needs to work

[@user-zw4pn9ks4q]

I just have a question...does air move in ALL directions? Someone plz answer! 🤞🏻

[@renaudg9311]

What do you mean exactly ? Air moves very faster horizontally than vertically, but yes it can move in all directions and reasons are explained in the video

[@AirTrafficControl1]

Yes it does... WIND IS AIR IN MOTION. Wind can be very unstable and random in both speed or directional change. Wind is mainly the product of pressure gradients established between high and low pressure systems. It works in a convection pattern: It is this movement that creates circulation patterns known as convection currents in the atmosphere (wind), in water (water currents), and in the mantle of Earth (lava). In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath. Convection currents in the atmosphere can exist on large scales, of kilometers or more, and can be well organised. Now... Wind may suffer changes in direction and speed (sometimes abruptly) due to other factors such as the Earth rotation (Coriolis effect), topography (topographic variations may affect wind direction due to surface friction), thermal wind relation (The balance of forces acting on an atmospheric air parcel in the vertical direction is primarily between the gravitational force acting on the mass of the parcel and the buoyancy force,or the difference in pressure between the top and bottom surfaces of the parcel. Any imbalance between these forces results in the acceleration of the parcel in the imbalance direction), the presence of large cloud masses/rain (when there are large shower clouds, the rain drags air down with it often at great speed - as fast as the rain falls. This descending air spreads out in all directions as in the sketch opposite and can give very strong gusts.) In summary, with due respect to the producers of this video (which is excellent) the idea that winds veer as air crosses from land to sea, is a bit an over-simplistic application of theory which has some good foundations but is bedeviled by the complexity of the atmosphere.

[@AsratMengesha]

Warm air from earth rise to cool air, to the atmosphere and that is wind? No, wind does not move up to the atmosphere. Wind is created from earth surface and moves around the surface horizontally after it grows to certain height into air.

[@renatapeters3681]

pls add commentary! I loved the video, but I don't like reading videos!

[@amitjain9400]

But not everyone lives in the coastal areas...??

[@Ashley-ro4xz]

Amit Jain just an easier example to understand. Sea is naturally cold. So it’s better example. :)

[@LFH1520]

this didnt help at all

[@Squidward6224]

Warm air floats, cold air floats down because it’s more heavy, and when the sun hits air and turns it warm it expands bigger. It is constantly expanding and the rising warm air causes the cold air to breeze around and that’s how it works very simple really. Warm air expands, it pushes the cold air away as it needs room to expand; the cold air pushes other air causing all the air to start moving and so on.

What is the cause of wind? Imaginary line called pressure gradient in the air? no. If you say yes, please create destructive moving wind to show that you know about winds. I said destructive, because you cannot create wind you just babble about it. right?
