Meteorology · Tropical Cyclones — Navigable Semicircle
The 'navigable semicircle' of a tropical cyclone (Northern Hemisphere) is the:
- AExact center (eye)
- BRight side, with the strongest winds
- CLeft side relative to the storm's track, where winds are weaker and tend to blow a vessel away from the path✓ Correct
- DArea 500 miles ahead of the storm
Explanation
In the Northern Hemisphere the left-hand semicircle (relative to the storm's motion) is the navigable semicircle: winds there are lighter (the storm's forward speed subtracts) and tend to set a vessel away from the track. The right-hand side is the dangerous semicircle, with stronger winds that can drive a vessel into the path.
