3 Winds near the surface of the Earth are also affected by friction (F), which acts in the opposite direction of wind, and slows the wind. The rougher the surface, the more winds are slowed. The amount of deflection due to the Coriolis force is then reduced because the amount of deflection is proportional to wind speed. This results in surface winds that tend to blow across isobars at an angle, as shown in Figure 6.5. Notice that the pressure gradient force magnitude is not affected because the pressure gradient was not changed. However, friction reduced the wind speed, and therefore reduced the Coriolis force.

Explain how the lines representing the forces and the wind in Figure 6.5 would change if there was a rougher surface.
