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

Quizplus · Accepted Answer

Without the frictional force, surface winds would only be influenced by the pressure gradient force and Coriolis force. This would result in winds flowing parallel to isobars and at high rates of speed, which is described by option B. Option A is incorrect because winds would not flow in a straight line due to the influence of the Coriolis force. Option C is incorrect because there would still be horizontal movement of air due to the pressure gradient force and Coriolis force. Option D is incorrect because surface texture does not have a significant influence on surface winds compared to the pressure gradient force and Coriolis force.
