What causes winds to deviate from straight -line paths?

Answer 1

Many things cause wind to alter its path. Wind can encounter other wind moving in another direction. It can encounter solid obstacles such as mountains. It can be affected by sunlight, causing hot air to rise from the ground.

Answer 2

The Coriolis effect is when earth's rotation causes winds and currents to deviate from a straight line trajectory. It makes hurricanes spin counter clockwise in the northern hemisphere.
