[ELI5] How does wind occur?


When the temperature changes in a certain spot all the air wants to go there, the air starts moving to that warm spot.

The sun heats the ground, and plumes of hot air rise. Then cooler air rushes in to replace it. Then the air cools off and sinks, pushing the air below it out to the sides. This gets crazy complicated, because when air moves north or south it starts moving east or west due to the difference in tangential speed between where it started and where it is now, but sunlight absorbed and heat radiated into space the primary energy flow that drives it.

Think of the air like water. Wind is the current of the fluid moving based on fluctuations in temperature.
