• 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!

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

• 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.
