Tropical cyclone intensity scales - Wikipedia
The JMA divides the typhoon category into three categories, with a 10-minute maximum wind speed below 84 kn (43 m/s; 97 mph; 156 km/h) assigned for the (strong) typhoon category. A very strong typhoon has wind speeds between 85–104 kn (44–54 m/s; 98–120 mph; 157–193 km/h), while a violent typhoon has wind speeds of 105 kn (54 m/s; 121 ...
Saffir–Simpson scale - Wikipedia
The Joint Typhoon Warning Center classifies typhoons of 150 mph (240 km/h) or greater (strong Category 4 and Category 5) as super typhoons. Most weather agencies use the definition for sustained winds recommended by the World Meteorological Organization (WMO), which specifies measuring winds at a height of 33 ft (10.1 m) for 10 minutes, and ...

2023年10月19日 · A typhoon in the Northwest Pacific Ocean west of the dateline (super typhoon if the maximum sustained winds are at least 150 mph / 241 km/h). A severe tropical cyclone in the Southwest Pacific Ocean west of 160°E or Southeast Indian Ocean east of 90°E.
Saffir-Simpson Hurricane Wind Scale - National Hurricane Center
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.
Classification of tropical cyclones - World Meteorological …
Tropical cyclones above a particular wind speed are classified for public safety. Depending on the maximum sustained wind speed, tropical cyclones are designated as follows: Tropical depression is when the maximum sustained wind speed is less than 63 km/h. Tropical storm is when the maximum sustained wind speed is more than 63 km/h.
Tropical Cyclone Classification - Hong Kong Observatory
Typhoon classification is introduced to facilitate the public in recognizing more intense typhoons, prompting people to be extra vigilant with the approach of more intense tropical cyclones. How does the new classification affect the Tropical Cyclone Warning System in Hong Kong?
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 about the possible impacts of various intensity hurricanes1.
List of Category 1 Atlantic hurricanes - Wikipedia
Category 1 is the lowest hurricane classification on the Saffir–Simpson scale. When a storm's wind speed is between 64 knots (74 mph; 119 km/h; 33 m/s) and 82 knots (95 mph; 153 km/h; 42 m/s), it is classified as a Category 1. [ 1 ]
Typhoon Category 1 On windward coasts, sea level rise of 4-6 ft above normal in open bays and inlets. Breaking waves inside bays can reach 5-7 ft; 2-3 ft. Additional water across reef. Waves may inundate low-lying coastal roads below 2-4 ft on windward locations where reefs are narrow. Minor pier damage and small craft in
