What wind speeds do cyclones reach?
Tropical Depression: A tropical cyclone with maximum sustained winds of 38 mph (33 knots) or less. Tropical Storm: A tropical cyclone with maximum sustained winds of 39 to 73 mph (34 to 63 knots). Hurricane: A tropical cyclone with maximum sustained winds of 74 mph (64 knots) or higher.
What cyclone has the highest winds?
The most intense storm in the Eastern Pacific Ocean by both sustained winds and central pressure was Hurricane Patricia. Its sustained winds of 345 km/h (215 mph) are also the highest on record globally.
What is the maximum wind speed of storm?
| Category | Sustained Winds |
|---|---|
| 2 | 96-110 mph 83-95 kt 154-177 km/h |
| 3 (major) | 111-129 mph 96-112 kt 178-208 km/h |
| 4 (major) | 130-156 mph 113-136 kt 209-251 km/h |

How long does a cyclone last?
While most cyclones undergo a life-cycle of 3-7 days some weak ones only briefly reach gale force while others can be sustained for weeks if they remain in a favourable environment.
What is the longest lasting storm in history?
Hurricane Irma Blasts Into The Record Books With Lasting Intensity : The Two-Way Hurricane Irma was the longest-lasting powerful hurricane or typhoon ever recorded, worldwide. It kept 185-mph winds for 37 hours — longer than any storm on record.
What’s the worst storm in the world?
Typhoon Haiyan was one of the largest and strongest typhoons ever recorded. It had winds that reached 195 miles per hour. Typhoons, like hurricanes, are powerful swirling cyclones. Image of Typhoon Haiyan taken from the International Space Station.
What part of the storm causes the most deaths?
Storm Surge
Storm Surge: The Deadliest Threat Roughly half of all U.S. deaths from tropical cyclones are due to the storm surge, the rise in water levels from the tropical cyclone’s winds piling water toward the coast just before and during landfall. Storm surge is not simply a function of the maximum winds.
Which country has the most tornadoes?
The United States
The United States has the most tornadoes of any country, as well as the strongest and most violent tornadoes. A large portion of these tornadoes form in an area of the central United States popularly known as Tornado Alley.
What is the strongest part of a cyclone?
eyewall
The most dangerous and destructive part of a tropical cyclone is the eyewall. Here winds are strongest, rainfall is heaviest, and deep convective clouds rise from close to Earth’s surface to a height of 15,000 metres (49,000 feet).
How do you know if a cyclone is coming?
The weather of a particular location can show signs of the approaching tropical cyclone, such as increasing swell, increasing cloudiness, falling barometric pressure, increasing tides, squalls and heavy rainfall.
