The dangerous semicircle of a hurricane in...

🔍 Key Concepts

• Hurricane structure in the Northern Hemisphere – how wind rotates around the eye • Relation of storm motion to wind direction – how the storm’s forward movement adds to or subtracts from the circular wind field • Difference between a dangerous semicircle and a navigable semicircle of a storm

💭 Think About

• Visualize looking down on a hurricane in the Northern Hemisphere: which way do the winds circulate, and what happens on the side where the storm’s motion and wind direction combine? • Think about which side of the storm will have stronger apparent winds and larger seas for a ship in the path of the hurricane. • Match the description of that ‘more dangerous’ side with the wording of the choices, focusing on storm track, not the ship’s heading or true north references.

✅ Before You Answer

• Identify which choices describe location relative to the storm’s own track, and which describe location relative to true north or the ship. • Recall that in the Northern Hemisphere, winds circulate counterclockwise around low-pressure systems like hurricanes. • Before choosing, be sure you can clearly picture which semicircle is typically called the dangerous semicircle versus the navigable semicircle.

The dangerous semicircle of a hurricane in the Northern Hemisphere is that area of the storm __________.

to the right of the storm's track

between the ship's heading and the bearing to the eye

measured from true north counterclockwise to 180° T
