What exactly is Wind? How does this “pressure” move things? How is the force built, that pushes the particles?
In: Physics
Air is heated by the sun. Warmer air rises, pushing the air above it out of the way (higher pressure) and causing the air below it to rush in to fill the gap (low pressure).
So air moves up causing sideways movement of air, which is what we call wind.
From my understanding wind is caused by the heating differences on earth.
Heat rises
Cold lowers
So as these differences interact it causes energy to build up and be expelled via wind
Pressure gradients. A bunch of hot molecules take up more space than a bunch of the same colder molecules. When parts of the atmosphere are heated by the Sun it expands and wants to take up more space so it rushes into cooler pockets of air because there’s available room for it to do so. That’s wind pretty much
Heat causes expansion, the sun heats the atomosphere unevenly, causing sections of the atmosphere to heat and therefore expand more than others, which may expand less or contract as they cool. If you have expanding air in one place, it moves outwards as it expands, which is wind.
Pressure and heat always go travel from high to low. Physics wants everything to be equal.
Hot materials warm up cooler ones around them until their temperatures are the same.
Pressure works the same way. Unless an outside force is at work, pressure inside a container is the same at all locations. If a force is applied, the air will move to achieve balance.
Wind is the movement of air from high to low pressure. Other have already stated why there are higher and lower pressure zones. You feel the wind because air has mass.
