Two important phenomena-. Convection currents - rising up of air with lower density; Coriolis Force. Earth is hotter near the equator and cold near the poles. This causes a general motion of wind from equator to poles in the upper layers of atmosphere. read more
Global Wind Patterns *Key Idea: Many factors affect winds, including the temperature difference between equatorial and polar regions, the rotation of Earth, the location of continents, the time of year, and local topography. read more
The factors that influence wind and contribute to global winds are pressure gradient, Rossby waves and jet streams, and local weather conditions. read more
