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.
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.
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 ...
Hurricane Ian was a prolific lightning producer as it strengthened into a Category 5 hurricane on its approach to Florida. Storm chasers along the coast of Florida even witnessed cloud-to-ground ...
Engineer Nick Underwood recorded the inside of Hurricane Helene while aboard NOAA’s “Miss Piggy,” one of the planes used to cut into the eyes of hurricanes. “Listen to your local officials.
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 ...
The structure of Hurricane Rita as seen by ELDORA radar. Most hurricanes exhibit a definitive eyewall and spiral rain bands outside of the eye. These spiral rain bands were known to be complex structures that possess deep convective cores enmeshed in low altitude precipitative clouds.
Live updates on Hurricane Milton are seen on tv as patrons drink and dine at the Copperhead Tavern’s bar in Melbourne Beach, as the hurricane approaches the West coast of Florida and then makes ...
