Due to friction, toward which type of pressure is the surface flow around a cyclone pointed?

• A. High pressure
• B. Low pressure
• C. Equal pressure
• D. Variable pressure

Answer: (B)

In the context of atmospheric pressure systems, surface flow around a cyclone is directed toward areas of low pressure. This phenomenon occurs because cyclones are characterized by a central region of lower atmospheric pressure relative to the surrounding areas. The pressure gradient between the high-pressure areas surrounding the cyclone and the low-pressure center creates a force that causes air to flow inward toward the center of the cyclone. Additionally, friction plays a significant role near the surface of the Earth. As the wind flows toward the low-pressure center, friction slows down the wind speed and causes the flow to spiral inward at an angle rather than directly towards the center. This results in a counterclockwise circulation pattern in the Northern Hemisphere (or clockwise in the Southern Hemisphere) around the cyclone. High pressure does not attract surface flow; rather, it causes flow away from it. The concepts of equal pressure and variable pressure do not accurately describe the dynamics involved in cyclone flow. Therefore, the inward-directed flow around a cyclone is primarily toward low pressure, supporting the correct answer.
