🔍 Key Concepts

• Dangerous semicircle vs navigable semicircle of a tropical cyclone • How the storm's forward motion combines with the rotational (cyclonic) winds • Role of pressure gradient in wind speed around a low-pressure center

💭 Think About

• On the dangerous semicircle, does the storm’s rotational wind add to or subtract from the storm’s forward motion? Compare that to the other semicircle. • Which factor directly creates stronger winds: the tilt/shape of the storm, the pressure gradient around the eye, or some special "recurvature" effect? • Look at which option mentions both a cause of strong rotational wind and the storm’s movement across the ocean—do both effects matter in the dangerous semicircle?

✅ Before You Answer

• Be clear on what pressure gradient means (change in pressure over distance) and how it affects wind speed. • Recall that in the dangerous semicircle in the Northern Hemisphere, winds tend to be strongest on the right-hand side of the storm’s track (looking in the direction of motion). • Check which options confuse structure features (like ridges or recurvature) with the direct mechanisms that increase wind speed.
