Why do the winds on Earth move the way that they do?

Question

I mean the winds as globally, not local. I know it has to do with the way that the Earth spins.

Oh and I already know about how the low air pressure rises and the high air pressure takes it place which causes wind but I need to know why they are moving a certain direction.

Answer 1

Wind is moving air. Warm air rises, and cool air comes in to take its place. This movement creates the winds around the globe. Wind is caused by different pressures in the atmosphere. Since the Earth spins, the winds try to move to the right in the northern hemisphere, and to the left in the southern hemisphere. This is called the Coriolis Effect .

Prevailing winds are a series of belts around the globe that produce steadily blowing winds near the surface. Trade winds are steady and flow towards the equator. Jet streams are narrow zones of very strong winds in upper troposphere.

Winds move at different speeds and have different names based on the Beaufort Scale. This scale is shown by numbers from 0 to 12 which goes from calm air to breezes to strong winds or gales . Winds are also grouped by their direction. Easterly winds blow from east to west, while westerly winds blow from west to east.

The fastest recorded wind speed is 230 miles per hour and occurred in New Hampshire in 1934. Although, winds can get faster in tornadoes. The windiest place in the world is in Antarctica.

Answer 2

The simple answer is convection combined with
corriolis force.
The details get complicated, but I'm a sucker for a cute avatar.
