The eye is a region of mostly calm weather at the center of a tropical cyclone. The eye of a storm is a roughly circular area, typically 30–65 kilometers (19–40 miles; 16–35 nautical miles) in diameter. It is surrounded by the eyewall, a ring of towering thunderstorms where the most severe weather and highest winds of the cyclone occur.
^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.
Severe Tropical Cyclone Alfred is a powerful tropical cyclone that is currently bringing severe effects to South East Queensland and New South Wales North Coast.As the seventh named storm, and sixth severe tropical cyclone of the 2024–25 Australian region cyclone season, Alfred originated from a tropical low in the Coral Sea on 20 February.
The outer bands of Tropical Cyclone Alfred are lashing Australia’s east coast with wind and rain as the rare southerly storm’s eye inches closer to landfall expected on Saturday morning.
Within 24 hours, the storm exploded from a Category 3 to a Category 5 cyclone with sustained winds up to 127 mph (205 kph) and gusts up to 177 mph (285 kph), according to the Australian Bureau of ...
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 eyewall has the strongest winds, heaviest rains and storm surges. Eye: A calm stretch of space usually less than 50 miles wide, that forms at the center of a tropical cyclone. The center can ...
The cyclone's lowest barometric pressure occurs in the eye, and can be as much as 15% lower than the atmospheric pressure outside the storm. [10] In weaker tropical cyclones, the eye is less well-defined or nonexistent, and can be covered by cloudiness caused by cirrus cloud outflow from the surrounding central dense overcast. [10]
