Where do global winds and pressure systems exist?

Answer 1

Global winds and pressure systems exist at the surface and at high altitudes. Surface winds include trade winds, westerlies, and polar easterlies. High altitude winds include high speed winds (which are often called jet streams). These high speed winds blow from the east in the low latitudes and from the west in the middle and high latitudes. Although local and seasonal variations occur, the wind and pressure patterns are generally predictable on the global scale. The high altitude wind and surface wind motions are related to each other.

Answer 2

Global winds and pressure systems exist in the Earth's atmosphere. These systems are driven by the unequal heating of the Earth's surface by the sun, which creates areas of high and low pressure. The movement of air from areas of high pressure to low pressure creates global wind patterns that circulate around the planet.
