What is the direction of air deflection by the Coriolis force in the Southern Hemisphere?

• A. Right
• B. Left
• C. Upward
• D. Downward

Answer: (B)

In the Southern Hemisphere, the Coriolis force causes moving air to deflect to the left of its original path. This phenomenon is a result of the Earth's rotation and affects all moving objects, including air masses. As the Earth spins from west to east, the surface moves faster at the equator than at higher latitudes. Because of this variation in speed, air in motion is deflected to the left compared to its direction of travel.

This leftward deflection plays a crucial role in the development of weather patterns and ocean currents in the Southern Hemisphere. For instance, it contributes to the circular motion of cyclones, leading to their characteristic counterclockwise rotation. Understanding this concept is essential for pilots, meteorologists, and anyone involved in aviation weather, as it helps predict the behavior of atmospheric systems.
