The Coriolis Effect is a result of the rotation of Earth. It has a direct impact on the directions of Earth's winds, as shown in the diagrams below. Northern hemisphere winds are deflected to the right, and Southern hemisphere winds are deflected to the left.
HOW DOES THE CORIOLIS EFFECT IMPACT THE EARTH'S CLIMATE?
It allows hurricanes to form at the equator from the cycling of wind in different directions
It keeps constant flow of energy throughout the planet so that all parts of the Earth have the same climate
It affects ocean currents, which transport warm surface water, evening out the distribution of heat on Earth's surface.
It makes the Northern Hemisphere windier than the Southern hemisphere, and the ocean current are stronger as well
