Answer:
Coriolis effect
Step-by-step explanation:
The rotation of the Earth is one of the climate modifiers. Considering the speed of the rotation, it is no wonder that it manages to influence the air masses and their movement in the lower atmosphere. Because of the rotation of the Earth, the air masses tend to swirl counterclockwise in the Northern Hemisphere, and clockwise in the Southern Hemisphere. This process is causing lot of large cycles to occur on both hemispheres, and it is known by the term Coriolis effect.
