Coriolis Effect

Do you know why winds and ocean currents don’t travel in straight lines? This is because of the Coriolis effect.

This effect occurs because the Earth rotates, causing moving objects like air and water to appear curved rather than traveling in a straight line.

It's not a force but an apparent change in motion caused by the Earth’s rotation. As the land beneath them rotates, their paths are altered relative to the Earth's surface.

In the Northern Hemisphere, winds and ocean currents seem to curve towards the right, while in the Southern Hemisphere, they curve to the left.

For example, when a plane flies north in the Northern Hemisphere, it must adjust its path to land because Earth’s rotation makes its straight path appear curved.

Similarly, winds and ocean currents are affected. Winds traveling toward the poles curve eastward, while those heading toward the equator curve westward, creating curved wind and current patterns.

The Coriolis effect is vital in shaping global weather systems, such as hurricanes, and helps distribute heat and energy.
