Which of the following best describes the figure above?
A)A high pressure center (anticyclone).
B)Winds influenced by both the pressure gradient and Coriolis forces.
C)Wind movement based on the pressure gradient force alone.
D)Geostrophic winds.

Question

Which of the following best describes the figure above?
A)A high pressure center (anticyclone). 
B)Winds influenced by both the pressure gradient and Coriolis forces. 
C)Wind movement based on the pressure gradient force alone. 
D)Geostrophic winds.

Quizplus · Accepted Answer

The figure shows parallel and straight isobars, which indicates geostrophic winds. Geostrophic winds are the result of the balance between the pressure gradient force and the Coriolis force. Therefore, option A and C can be eliminated. Option B is incorrect because it suggests both forces are influencing the wind movement, whereas geostrophic winds are only influenced by two forces - the pressure gradient force and the Coriolis force.
