It RISES...
After high-pressure areas are formed around the poles, cold polar air flows towards lower pressure regions. This movement of air is known as advection, and it helps to balance out the pressure differences between the poles and lower latitudes.
Earths Rotation The Coriolis effect
Polar easterlies are dry, cold prevailing winds that blow from the east. They emanate from the polar highs, areas of high pressure around the North and South Poles. Polar easterlies flow to low-pressure areas in sub-polar regions. Westerlies are prevailing winds that blow from the west at midlatitudes.
Convection cells heat the air at the equator, causing it to rise and flow towards the poles. As the air rises, it cools and sinks back down towards the surface in the subtropical regions. This sinking air creates areas of high pressure at around 30 degrees latitude in both hemispheres.
Unequal heating of Earth's surface causes differences in temperature, creating areas of high and low pressure. Warm air rises at the equator, creating low pressure, while cold air sinks at the poles, creating high pressure. Wind then flows from areas of high pressure to areas of low pressure to equalize the pressure difference, resulting in the formation of wind patterns.

Earths Rotation The Coriolis effect
The global wind systems located at the North and South Poles are known as polar easterlies. These winds blow from the high-pressure areas around the poles towards lower-pressure areas at mid-latitudes. Polar easterlies are characterized by cold, dry air and play a significant role in influencing weather patterns in polar regions and beyond.

Polar easterlies flow to low-pressure areas in sub-polar regions. Westerlies are prevailing winds that blow from the west at midlatitudes.
Wind currents flow faster at the poles than at the equator. This is due to the Coriolis effect, which causes the winds to be deflected as they move from high pressure to low pressure areas, creating stronger winds at higher latitudes. Additionally, temperature differences between the equator and the poles contribute to the strength of wind currents.
Wind travels around the world due to the Earth's rotation, heating imbalances between the equator and the poles, and the Coriolis effect. These factors together create global wind patterns that move air masses from high pressure to low pressure areas, resulting in the circulation of wind around the world.
Convection cells heat the air at the equator, causing it to rise and flow towards the poles. As the air rises, it cools and sinks back down towards the surface in the subtropical regions. This sinking air creates areas of high pressure at around 30 degrees latitude in both hemispheres.
These are obviously called the "polar zones," the Arctic and the Antarctic.
Distinct pressure zones between the poles are primarily caused by the uneven heating of the Earth's surface by the sun. This differential heating leads to variations in air temperature and density, creating high-pressure areas at the poles and low-pressure zones in the warmer equatorial regions. Additionally, the Earth's rotation contributes to these pressure differences through the Coriolis effect, influencing wind patterns and further reinforcing the distinct pressure zones.
The wind that blows in a relatively straight line from the poles to the equator is known as the polar easterlies. These winds occur in the polar regions and flow towards the equator, primarily due to the Coriolis effect, which causes them to curve. However, the overall movement of air from high-pressure areas at the poles towards low-pressure areas near the equator is influenced by other wind systems, such as the trade winds.
