Explain how the rotation of Earth affects atmospheric circulation

Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect ... But because the Earth rotates, circulating air is deflected.

Because Earth rotates on its axis circulating air is deflected towards the right in the Northern Hemisphere and toward the left in the southern hemisphere. this deflection is called the Coriolis effect. Coastal currents are affected by wind.
