The equators warm air, and the polar cold air.
At the poles, cold air sinks. Simple
Away from the poles because the air near Earths surface is warm.
Warm air rises at the equator and cold air sinks at the poles. Warm air expands and cool air contracts and compresses.
These looping patterns of air flow are called Hadley cells near the equator, Ferrel cells in the mid-latitudes, and Polar cells near the poles. This atmospheric circulation helps redistribute heat and moisture around the Earth.

As air gets colder it contracts. While the total amount of air is about the same in any column of the troposphere, at the cold poles that column takes up less space, resulting in a shorter distance to the top of the troposphere.
Generally the poles are cold places, receiving Sunlight at a low angle or no Sun at all. This means the air above the poles tends to be cooler than the rest of the planet. Cold air is dense so the pressure of the air at the poles tends to be higher than the rest of the planet. Thus air (cold air) tends to flow away from the polar regions along the Earth's surface to be replaced by light warmer air flowing into the poles at a higher level (this air then cools). There is therefore a general flow of warm air north and south towards the poles from the equator and a flow of cold air from the poles towards the equator. This flow of air spreads out the heat from the Sun, warming the poles and cooling the tropics. In detail this overall flow is restricted by the thickness of Earth's atmosphere and several flow cells form to complete the chain causing Earth's climatic zones.

Air flows from the poles to the equator due to the temperature difference between the two regions. Warm air rises at the equator, creating a low-pressure system, while cold air sinks at the poles, creating a high-pressure system. This pressure difference causes air to flow from the poles towards the equator to balance out the pressure.

Purchase a can of mass air flow cleaner and follow the directions on the can. Don't try to clean it with anything else!
Actually, cool air tends to be more dense and flow under warm air
