Coriolis effect is caused by Earth’s rotation.

1. ` • Coriolis effect is caused by Earth’s rotation. • Wind is turned to the right relative of Earth’s surface in the Northern Hemisphere and to the left relative to Earth’s surface in the Southern Hemisphere. • It must always be taken into account, even for launching rockets!

6. High Pressure in N.H. - air flows outward and clockwise • Low Pressure in N.H. - air flows inward and counterclockwise

12. Friction also plays a larger role in how winds blow. • Friction from the ground slows down the air and lessens the Coriolis effect. • This is why it is often very windy near the ocean, at sea, or in places like Antarctica where the surface is all ice.
