^α Although Luis produced the highest confirmed wave height for a tropical cyclone, it is possible that Hurricane Ivan produced a wave measuring 131 feet (40 m). [41]^β It is believed that reconnaissance aircraft overestimated wind speeds in tropical cyclones from the 1940s to the 1960s, and data from this time period is generally considered unreliable.
Out of all these tropical cyclones, Typhoon Tip had the lowest atmospheric pressure measured in a tropical cyclone, at 870 mbar (25.69 inHg). It is the third image in the first row. This is a list of the most intense tropical cyclones as measured by minimum atmospheric pressure at sea level.
The 10 costliest Atlantic hurricanes as of January 2023.. As of November 2024, there have been 1,745 tropical cyclones of at least tropical storm intensity, 971 at hurricane intensity, and 338 at major hurricane intensity within the Atlantic Ocean since 1851, the first Atlantic hurricane season to be included in the official Atlantic tropical cyclone record.

Tropical cyclones are named for historical reasons and so as to avoid confusion when communicating with the public, as more than one tropical cyclone can exist at a time. Names are drawn in order from predetermined lists. They are usually assigned to tropical cyclones with one-, three-, or ten-minute windspeeds of at least 65 km/h (40 mph).
Depictions of Typhoon Tip and Cyclone Tracy (one of the smallest tropical cyclones ever recorded) superimposed on a map of the United States. Typhoon Tip was the largest tropical cyclone on record, with a diameter of 1,380 mi (2,220 km)—almost double the previous record of 700 mi (1,130 km) in diameter set by Typhoon Marge in August 1951.
A tropical cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. [4] [5] The systems generally have a well-defined center which is surrounded by deep atmospheric convection and a closed wind circulation at the surface. [4]
A very intense tropical cyclone is the highest category on the South-West Indian Ocean Tropical Cyclone scale, and has winds of over 115 knots (213 km/h; 132 mph). [24] [25] At the tenth RA I tropical cyclone committee held during 1991, it was recommended that the intensity classifications be changed ahead of the 1993–94 tropical cyclone season.
The following is a list of tropical cyclones by year. Since the year 957, there have been at least 12,791 recorded tropical or subtropical cyclones in the Atlantic, Pacific, and Indian Oceans, which are known as basins. Collectively, tropical cyclones caused more than US$1.2 trillion in damage, unadjusted for inflation, and have killed more ...
