Why are there global winds?

Answer 1

Global winds are primarily driven by the uneven heating of the Earth's surface by the sun. This creates differences in air temperature and pressure, leading to the movement of air from high-pressure areas to low-pressure areas. Additionally, the rotation of the Earth (Coriolis effect) influences the direction of these winds, resulting in prevailing wind patterns such as trade winds and westerlies. Together, these factors contribute to the dynamic circulation of the atmosphere on a global scale.
