Tropical cyclones
7 questions tagged Tropical cyclones — spanning every one of the seven Ws.
Where is the eyewall of a hurricane located?
The eyewall is the ring of intense storms surrounding the calm eye at the center of a hurricane. It is located just outside the eye and contains the strongest winds and heaviest rain.
Which tropical cyclone holds the record for the highest sustained wind speed ever measured?
Cyclone Olivia reached estimated 10-minute sustained winds of about 200 mph (322 km/h) over Australia in 1996. It is one of the strongest tropical cyclones ever measured anywhere.
Which ocean basin is most associated with the strongest tropical cyclones by frequency of Category 5 storms?
The western North Pacific is the most active basin for intense tropical cyclones and has produced many Category 5 typhoons. It is the busiest tropical cyclone region on Earth.
Which storm produced the lowest barometric pressure ever measured at sea level in a tropical cyclone?
Typhoon Tip in 1979 reached the lowest sea-level pressure ever measured in a tropical cyclone, at 870 hPa. It remains a legendary cyclone record.
How do hurricanes and typhoons get their energy from warm oceans?
Tropical cyclones draw energy from warm seawater, especially when ocean temperatures are at least about 26.5 °C. Evaporation and condensation release heat that helps the storm intensify.
Which ocean has the strongest recorded tropical cyclone?
The strongest tropical cyclone on record by sustained wind is Typhoon Tip in the western North Pacific, with estimated peak winds of 305 km/h (190 mph) in 1979.
How do hurricanes lose or gain strength over warm ocean water?
Hurricanes intensify when they move over warm, moist ocean water and weaken over cooler water or land.
