Why are these winds called the polar easterlies?

The polar easterlies are winds that originate from the polar regions, specifically the Arctic and Antarctic, and blow towards the equator. They are called "easterlies" because they predominantly come from the east. As cold air descends at the poles, it creates high-pressure areas, resulting in these winds flowing outward from the poles, typically deflected westward due to the Coriolis effect. This pattern contributes to the overall circulation of the Earth's atmosphere.
