Wind exists because of two main forces: The rotation of the earth, and the heat and light from the sun.
The rotation of the earth causes wind because the natural tendency of air molecules is to stay still. The earth essentially is moving, and the air is essentially staying where it is, creating the illusion that the air is moving. This is called "the Coriolis Effect". The Coriolis effect is what causes the constant unchanging winds used by sailing ships.
The heat from the sun is responsible for almost all of earth's weather, except for those mentioned above. The sun's heat causes the air molecules to become excited, and lack of heat makes the molecules stand still. Excited molecules expand, and create High Pressure. Still molecules contract and create low pressure. When high pressure air moves in to fill in the slight vacuum created by low pressure air, it creates wind.
In short
HOT AIR = HIGH PRESSURE
COLD AIR = LOW PRESSURE
HIGH PRESSURE TRIES TO GET TO WHERE THERE IS LESS PRESSURE.
What else can I help you with?
Do waves need the wind?
Waves can be generated by wind, but other factors like tides and seismic activity can also create waves. Once waves are generated, they can propagate across the ocean without direct wind involvement. Therefore, while wind can influence waves, it is not always necessary for waves to exist.
What conditions exist during a tornado?
Two main weather conditions exist to create a tornado: instability in the atmosphere and wind shear in the lower atmosphere. In the case of a tornado, instability refers to the presence of warm air closer to the Earth's surface and cooler air further above the surface. Wind shear refers to instances when the wind direction changes, and wind speed increases, with height. These conditions usually exist only ahead of a cold front and low pressure system, and are especially found in thunderstorms. The spinning motion of tornadoes is often caused by the interaction between the updrafts and downdrafts in the thunderstorm and the wind shear. The conflicting drafts cause the wind shear to tilt, and an upright tornado vortex is formed.
How do you calculate wind pressure exerted on electric cable?
Equations already exist to convert wind speed to wind pressure, One is from the National Research Council of Canada, with the "stagnation pressure" given by (air density) * (wind speed)^2. Another from K7NV Amateur Radio that puts wind pressure [lb/ft^2] = 0.00256* (wind speed [mi/h])^2. [reference: http://www.arraysolutions.com/Products/windloads.htm]. What are unknowns in this question are the wind speed from the windward side and that from the leeward side, with the cable being replaced by its projected area.
How do you know particles exist?
Particles exist because they have been observed and studied in various experiments and through the use of powerful scientific instruments like particle accelerators. Their behavior and interactions have been well-documented and their existence is supported by numerous experiments and scientific theories in the field of particle physics.
Do wind turbines come in different shapes?
Yes, wind turbines come in different shapes and sizes depending on the design and intended use. The most common shape is the horizontal-axis turbine with three blades, but vertical-axis turbines and other designs also exist for specific applications. Different shapes can affect efficiency, performance, and cost of wind turbines.
How can updrafts and downdrafts exist in the same thundercloud?
the updraft wind goes up and the down draft wind goes down
How do wind sensors work?
An anemometer is a device that provides information on wind speed and wind pressure. Sonic anemometers measure the wind speed and pressure of sonic pulses that exist between pairs of transducers.
What are the wind condition for a large wave to exist?
Well it depends. If its a big wave, there lots of wind. If its a small wave, there's probably little wind. It has to be strong enough. Surprisingly, waves comes from wind.
Does skull kid exist in wind waker using cheats?
Nope :P
How do you know wind exist?
Wind always exists no matter if you feel it or not Hope this helps =) Edit: some might say "by it's effects"
Where are heavy wind tunnels in the US?
NASA has a wind tunnel available in Texas, others do exist in the USA but have undisclosed locations as heavy wind tunnels are often used to test aircraft.
How is wind power related to chemistry?
Very probable a significant relation doesn't exist.
Which is stronger wind or earth?
No element is stronger than another. Each needs the others to exist.
Why do ideal conditions for wind action exist in many parts of southern Pakistan?
Beacause it is desrted
What would happen if the sand dunes did not have wind?
The whole beach or whatever it was on would be totally flat. Wind is what shapes sand dunes. Without it, they just would not exist.
How is Gone With the Wind rated?
The rating system didn't exist when it was released in 1939, but it was rated 'G' in 1971.
Does skull kid exist in wind waker?
Unfortunately, no. Skull kid in windwaker would be adorable, though.
