Final answer:
Winds are influenced by high and low pressure systems created by convection currents in the atmosphere. The rotation of the Earth causes the wind to appear to curve due to the Coriolis force.
Step-by-step explanation:
Winds occur due to the high and low pressure systems created by the convection currents in the atmosphere. The winds blow in a straight line. Due to the Earth's rotation, the winds that are originating at the poles appear to curve towards the west. The wind isn't actually curving, it is the position of the Earth that is moving causing the wind to appear to curve.
The Coriolis force causes hurricanes in the northern hemisphere to rotate in the counterclockwise direction, while the tropical cyclones in the southern hemisphere rotate in the clockwise direction. This force is due to the rotation of the Earth and the deflection of winds caused by it.
In summary, winds are influenced by the high and low pressure systems created by convection currents in the atmosphere, and they appear to curve due to the rotation of the Earth, which causes the Coriolis force.
