Meteorology · Tropical Cyclones — Saffir-Simpson
The Saffir-Simpson Hurricane Wind Scale categorizes hurricanes (1 to 5) based on:
- ACentral pressure only
- BRainfall total
- CMaximum sustained wind speed✓ Correct
- DStorm diameter
Explanation
The scale rates hurricanes Category 1 through 5 by maximum sustained wind speed, indicating potential property damage. A Category 1 begins at 64 knots (74 mph); Category 5 exceeds 137 knots (157 mph).
