While we often see cyclones as perfect circles on satellite maps, their actual pressure patterns can vary. They are most commonly circular or oval-shaped. However, temperate cyclones can also appear “V-shaped” when they have strong fronts attached to them. Their shape is determined by how the air is moving and the surrounding environmental pressure. ANSWER: (D) All of the above

In a textbook, a cyclone is usually drawn as a series of concentric circles called isobars. In reality, these systems are flexible. Tropical cyclones (like hurricanes) tend to be more perfectly circular because they are fueled by a single warm air mass. Temperate cyclones, which form between 30° and 60° latitude, are often oval or “V-shaped” because they are being stretched by the meeting of different air masses. Regardless of the specific geometry, the shape always represents a closed loop of low pressure where the winds are being funneled toward the center.
