How do the winds circulate?

  • Exhibition Text

    • Wind circulation is powered by the Sun’s uneven heating of the Earth’s surface, and by the Earth’s rotation. The uneven heating causes giant circulation patterns, called Hadley cells, in which warm equatorial air flows toward the poles, and cold polar air streams back to replace it. The Earth’s rotation causes winds to flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere. This is called the Coriolis effect.
