When Hurricane Ian made landfall along Florida's Gulf Coast on Sept. 28, 2022, Fort Myers, Florida, and surrounding areas were blasted by the right front quadrant and sustained catastrophic damage.
Cross section of a mature tropical cyclone. A typical tropical cyclone has an eye approximately 30–65 km (20–40 mi) across at the geometric center of the storm. The eye may be clear or have spotty low clouds (a clear eye), it may be filled with low-and mid-level clouds (a filled eye), or it may be obscured by the central dense overcast.
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]
The hurricane attained its peak intensity later that night with maximum sustained wind of 140 mph (220 km/h) and a minimum barometric pressure of 938 millibars (27.70 inHg) at 3:10 UTC on September 27 as it made landfall east of the center of the Aucilla River about 10 miles (16 km) west-southwest of Perry, Florida, [16] becoming the strongest ...
The strongest hurricane to reach land was the Labor Day Hurricane of 1935 (892 hPa). [12] The deadliest hurricane was the Great Hurricane of 1780 (22,000 fatalities). [54] The deadliest hurricane to make landfall on the continental United States was the Galveston Hurricane in 1900, which may have killed up to 12,000 people. [55]
The hurricane made landfall with the same intensity between the mouth of the Sabine River and Cameron, Louisiana, later that day, causing unprecedented destruction across the region. Once inland, Audrey weakened and turned extratropical over West Virginia on June 29. Audrey was the first major hurricane to form in the Gulf of Mexico since 1945.
In meteorology, a cyclone (/ ˈ s aɪ. k l oʊ n /) is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone).
However, the National Hurricane Center (NHC) later started used the Annular Hurricane Index for the purpose of assessing annular tropical cyclones. The index takes into account the cloud height of the storm, the radii of the eye, and other similar factors, using satellite imagery, and then produces a number, with the maximum value on the scale ...
