If air moves south from the equator, the Coriolis effect deflects it in which direction?

Explanation:
The Coriolis effect appears because Earth spins. In the Southern Hemisphere, moving objects are deflected to their left. If air travels south from the equator, facing south, a leftward deflection points toward the east. Intuitively, air from the equator carries a faster eastward speed than air at higher southern latitudes, so as it moves south it keeps that faster eastward motion and lags behind the ground—resulting in an eastward deflection. That’s why the correct direction is east.
