What is Wind?
Wind is the movement of air from areas of high pressure to areas of low pressure. Wind is also a force in air, and this is known by the blowing of wind. Wind is often described as wind gust because we mostly feel wind when it gust up. The highest wind speed ever recorded was 318 MPH in a tornado.
What Causes Wind?
Most wind is caused by air pressure in the troposphere. When there is a difference in air pressure, wind moves from a high pressured area to a low pressured area. Near Earth's surface, the planets friction causes the wind to slow down. This is proven by the laws of gravity.
What are Local Winds?
Local winds are winds that are in one particular area. This happens mostly in local terrain like a city. If the local terrain is varied like: flat land, hills, mountains, etc. So when you look at the NWS [National Weather Service] and it says the wind speed for your state, don't ever trust that because they are talking about global winds, not local winds.
What Are Global Winds?
Global winds are winds that blow over a large area like the Earth. The Earth has six major wind belts. They are: Trade Winds, Horse Latitude, Doldrums, Prevailing Winds Polar Easterlies, and Polar Westerlies.
How Are Global Winds Created?
Global winds are created by something called the Coriolis Effect. The Earth has a lot of pressure. Some areas have low pressure and high pressure. If there was no Coriolis Effect, the wind would just go North to South.
What Are Doldrums?
Doldrums are located on the equator. it is a low pressured area that makes the wind very weak. Doldrums made sailors hate the equator because it was very hard to sail on. This is why it's called Doldrums.
