The Coriolis force is an apparent force that acts on objects moving within a rotating system, such as the Earth. It causes moving objects to follow a curved path rather than a straight line. This effect is most noticeable in large-scale movements, like wind patterns and ocean currents. In the Northern Hemisphere, the Coriolis force causes moving objects to deflect to the right, while in the Southern Hemisphere, they deflect to the left. This phenomenon is crucial for understanding weather systems, as it influences the direction of storms and the rotation of large-scale wind patterns, such as cyclones.
