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.
Surrounding the eye of the hurricane is a ring of thunderstorms, called the eyewall. Rainbands surround the eye of the storm in concentric circles. In the eyewall and in the rainbands, warm, moist air rises, while in the eye and around the rainbands, air from higher in the atmosphere sinks back toward the surface.
Concentric eyewalls seen in Typhoon Haima as it travels west across the Pacific Ocean.. In meteorology, eyewall replacement cycles, also called concentric eyewall cycles, naturally occur in intense tropical cyclones with maximum sustained winds greater than 33 m/s (64 kn; 119 km/h; 74 mph), or hurricane-force, and particularly in major hurricanes of Saffir–Simpson category 3 to 5.
A Hurricane Hunters engineer captured video from inside Hurricane Helene's eye Wednesday after it formed along the Gulf of Mexico.
The 403rd Wing of the Air Force Reserve Hurricane Hunter's plane got quite the view of Category 5 Hurricane Lee as lightning flashed in the storm's eye on Thursday night. 📷: @53rdWRS/Lt. Col ...
The ominous eye of Hurricane Milton is visible in stunning detail from outer space in a timeplapse video released Tuesday by NASA.. From 275 miles above Earth, the powerful storm can be seen ...
Mesovortices visible in the eye of Hurricane Emilia in 1994. An eyewall mesovortex is a small-scale rotational feature found in an eyewall of an intense tropical cyclone. Eyewall mesovortices are similar, in principle, to small "suction vortices" often observed in multiple-vortex tornadoes. In these vortices, wind speed can be up to 10% higher ...
Satellite images show the extent of the damage from Hurricane Milton, which spawned tornadoes across Florida and struck the state as a Category 3 hurricane.. The fatal storm surge that forecasters ...
