What characteristic makes LP systems highly mobile?

• A. They remain stationary once formed.
• B. They always maintain the same wind direction.
• C. They are very mobile.
• D. They occur only in the Southern Hemisphere.

Answer: (C)

Low pressure systems move with the larger-scale atmospheric flow. Their centers are steered by upper-level winds (the jet stream and prevailing westerlies), so they drift across regions rather than staying fixed. This steering makes LP systems highly mobile, able to travel long distances and shift position as the atmosphere evolves. They don’t stay in one spot, they don’t always keep the same wind direction as they move, and they form in both hemispheres, not only in the Southern Hemisphere.
