What are some of the factors that might interrupt the wind blowing in a straight line forever?

Differences in temperature, seas or oceans, mountains and valleys, Coriolis effect are the factors that might interrupt the wind blowing in a straight line forever

Explanation:

The wind is nothing but the gases flow on a mass scale. In the Earth's surface, the wind is known for the motion of air in bulk amount.

Each region on the earth has different wind speeds in different directions. Thus the direction and speed of the wind can be changed based on several factors.  

They are temperature, mountains, and valleys, seas or oceans, and Coriolis effect( earth's rotation). These factors change the pressure in the air that eventually changes the direction of the air.
