The Saffir–Simpson hurricane wind scale (SSHWS) is a scale that classifies hurricanes—which in the Western Hemisphere are tropical cyclones that exceed the intensities of tropical depressions and tropical storms—into five categories distinguished by the intensities of their sustained winds.

A severe tropical storm is designated as a tropical cyclone when it reaches wind speeds of 64 knots (119 km/h; 74 mph). If a tropical cyclone intensify further and reaches wind speeds of 90 knots (170 km/h; 100 mph), it will be classified as an intense tropical cyclone.

2023年10月19日 · Once the tropical cyclone reaches winds of at least 39 mph (63 km/h), they are typically called a "tropical storm" and assigned a name. If maximum sustained winds reach 74 mph (119 km/h), the cyclone is called: A hurricane in the North Atlantic Ocean, the Northeast Pacific Ocean east of the dateline, and the South Pacific Ocean east of 160°E ...

The Saffir-Simpson Hurricane Wind Scale estimates potential property damage. While all hurricanes produce life-threatening winds, hurricanes rated Category 3 and higher are known as major hurricanes*. Major hurricanes can cause devastating to catastrophic wind damage and significant loss of life simply due to the strength of their winds.

Tropical storm, organized centre of low pressure that originates over warm tropical oceans. The maximum sustained surface winds of tropical storms range from 63 to 118 km (39 to 73 miles) per hour. These types of tropical cyclones represent an intermediate stage between loosely organized tropical depressions and more intense storms, which are ...

The Saffir-Simpson Hurricane Wind Scale is designed to help determine wind hazards of an approaching hurricane easier for emergency officials. The scale is assigned five categories with Category 1 assigned to a minimal hurricane and Category 5 to a worst case scenario.

2023年8月2日 · Tropical Storm: A tropical depression is upgraded to a tropical storm when its sustained wind speeds range between 39-73 mph (63-118 km/h or 34-63 knots). These storms are assigned names by meteorological agencies and can cause minor damage.

2023年9月8日 · A 10 mph (16 km/h) increase in wind speed, from 100 mph (161 km/h) to 110 mph (177 km/h), results in over doubling potential damage from 10-times that of a 75 mph (121 km/h) hurricane to 21-times. What does this mean for you?

The Saffir-Simpson Hurricane Wind Scale Updated May 2021 The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 categorization based on the hurricane's intensity at the indicated time. The scale – originally developed by wind engineer Herb Saffir and meteorologist Bob Simpson – has been an excellent tool for alerting the public
