Explain how near-surface winds move in a spiral into the center of a cyclone while the entire cyclone moves along
What will be an ideal response?
Answer: The central low pressure causes a gradient and the three forces of the winds cause the winds to spiral into the low at an angle across the isobars. Yet, the low moves along in a predictable direction because it is caused and steered by the winds of the polar front jet stream.
