If surface winds were influenced only by the pressure gradient force and Coriolis force (i.e.without the frictional force),how would wind be affected?
A)Wind would flow in a straight line from areas of higher to lower pressure.
B)Wind would flow parallel to isobars and at high rates of speed.
C)There would be no wind at all.
D)The effects would vary depending on surface texture.

Without frictional force, the wind will flow parallel to isobars (lines of equal pressure) and at high speeds due to the balance between the pressure gradient force and Coriolis force. This is called geostrophic flow, and it is mainly observed at high altitudes where friction is weak.
