Answer:
The coriolis effect changes the direction of the wind.
Step-by-step explanation:
The earth´s rotation affects objects that are moving over its surface. The Coriolis effect curves the initial direction of winds that move between two points of high and low pressure, altering their course. By Coriolis effect, air masses are diverted into predictable directions. This rotation effect has an important role in winds´ direction but not in their velocity.
In the Northern Hemisphere, winds blow counterclockwise around the low-pressure zones and clockwise in the high-pressure zones. The opposite occurs in the southern hemisphere. So cyclones and hurricanes in the north rotate counterclockwise, contrary to what happens below the equator.
