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.
When an outer eyewall is formed, the moisture and angular momentum necessary for the maintenance of the inner eyewall is now being used to sustain the outer eyewall, causing the inner eye to weaken and dissipate, leaving the tropical cyclone with one eye that is larger in diameter than the previous eye. A microwave pass of Cyclone Phailin ...
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. In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall.
Eye: A calm stretch of space usually less than 50 miles wide, that forms at the center of a tropical cyclone. The center can be completely devoid of clouds or rain, making the center a sort 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]
An extratropical cyclone can transform into a subtropical storm, and from there into a tropical cyclone, if it dwells over warm waters sufficient to warm its core, and as a result develops central convection. [37] A particularly intense type of extratropical cyclone that strikes during winter is known colloquially as a nor'easter.
However, Dr. Russo says that “flu A usually causes more severe disease than flu B.” Meaning, if you have flu A, your doctor may want to keep a closer eye on you.
Intense Tropical Cyclone Chido was a compact but very powerful, destructive, and deadly tropical cyclone which impacted Southeast Africa in December 2024. Chido, which means a desire in Shona , was the third named storm and the second intense tropical cyclone of the 2024–25 South-West Indian Ocean cyclone season .
