Final answer:
The Coriolis effect combined with wind cells establishes ocean currents, strongly influencing the rotation of weather systems like hurricanes and affecting their direction in different hemispheres.
Step-by-step explanation:
The Coriolis effect, along with wind cells, plays a significant role in the establishment of ocean currents. This phenomenon affects the movement of air and water around the Earth due to the planet's rotation. In the Northern Hemisphere, the deflection is to the right which causes hurricanes to spin counterclockwise, while in the Southern Hemisphere, it is to the left, leading to a clockwise rotation in tropical cyclones. The counterclockwise and clockwise rotations of these storm systems are major consequences of the Coriolis force, which is substantial for large-scale motions such as wind patterns and ocean currents.
