Which is TRUE of the dangerous semicircle of a typhoon in the Southern Hemisphere?

🔍 Key Concepts

• Southern Hemisphere cyclone rotation and how it differs from the Northern Hemisphere • What dangerous semicircle means in relation to a storm’s track and wind direction • How a ship’s motion plus wind direction can increase or decrease dangerous winds and seas

💭 Think About

• Sketch the storm’s center, show its track, and draw the wind circulation arrows for a Southern Hemisphere typhoon. On which side do winds tend to blow a vessel toward the storm track? • Compare how the dangerous semicircle is defined in the Northern Hemisphere. Then mentally ‘flip’ the situation for the opposite rotation in the Southern Hemisphere. • Think about where a vessel’s forward motion would combine with the storm’s wind to make conditions worse versus where they would partially cancel each other.

✅ Before You Answer

• Be clear on clockwise vs counterclockwise rotation in the Southern Hemisphere low-pressure system. • Identify which side of the track produces on-coming winds that set you toward the storm’s path. • Check whether the option describes location relative to storm track or cardinal directions (N/S). The standard definition is based on the track, not on compass bearings from due south.

Which is TRUE of the dangerous semicircle of a typhoon in the Southern Hemisphere?

It is the area to the left of the storm's track

The area is measured from due south clockwise 180°

It is measured from due south counterclockwise 180°

It is ahead of the typhoon measured from the storm's track to 90° on each side
