In the Southern Hemisphere, the Coriolis force acts to the left of the direction of motion. This is a result of the Earth's rotation and its effects on moving objects. The Coriolis effect is caused by the fact that the Earth rotates counterclockwise when viewed from above the North Pole and clockwise when viewed from above the South Pole. In the Southern Hemisphere, as an object moves, the surface of the Earth rotates beneath it, causing a deflection to the left relative to the object's path.

Understanding the Coriolis force is essential in meteorology, as it affects wind patterns and ocean currents. For instance, the trade winds and prevailing westerlies are influenced by this deflection, contributing to the overall circulation of the atmosphere. The leftward deflection in the Southern Hemisphere also plays a critical role in the formation and direction of cyclones, which spiral in a counterclockwise manner.
