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.
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.
Annular hurricanes have been simulated that have gone through the life cycle of an eyewall replacement. The simulations show that the major rainbands will grow such that the arms will overlap, and then it spirals into itself to form a concentric eyewall. The inner eyewall dissipates, leaving a hurricane with a singular large eye with no rainbands.
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 ...
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.
Inside the eye of Hurricane Lee. Friday 8 September 2023 16:15, Louise Boyle. The US Air Force Reserve’s “Hurricane Hunters” shared dramatic footage from inside Hurricane Lee on Thursday night.
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 ...
The StreamSonde is a lighter and smaller take on the dropsonde, a bundle of instruments in a large cylinder to measure conditions inside a hurricane that has been the research workhorse of the ...
