What two factors determine the directions of the global winds?

The directions of global winds are primarily determined by the Earth's rotation and the uneven heating of its surface. The Coriolis effect, caused by the Earth's rotation, causes winds to curve rather than flow in a straight line. Additionally, differences in temperature and pressure due to solar heating create convection currents, leading to the formation of distinct wind patterns, such as trade winds and westerlies. Together, these factors shape the global wind systems.
