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.
1 giu 2022 · The objectives are to identify the tropical cyclone (TC) characteristics associated with these two types of eye formation and to clarify how the environment, pattern of synoptic systems, and TC structure during initial and development stages affect the eye formation.
The main parts of a tropical cyclone are the rainbands, the eye, and the eyewall. Air spirals in toward the center in a counter-clockwise pattern in the northern hemisphere (clockwise in the southern hemisphere) and out the top in the opposite direction.
25 mag 2018 · Tropical cyclones are one of the most dangerous weather events on Earth, but at their core lies a paradox—an area of clear skies and calm winds called the eye. The eye is surrounded by an eyewall, which is composed of towering clouds, intense severe weather, and the storm’s strongest winds.

8 feb 2023 · The radius of maximum wind (RMW) of tropical cyclone (TC) is an important factor for TC intensity estimation and disaster prevention. A previous study suggested that the RMWs of TCs with clear eyes can be estimated from geostationary satellite images at a mean absolute error (MAE) of 4.7 km.
7 mag 2024 · As the air subsides, it compresses slightly and warms, so that temperatures at the centre of a tropical cyclone are some 5.5 °C (10 °F) higher than in other regions of the storm. Because warmer air can hold more moisture before condensation occurs, the eye of the cyclone is generally free of clouds.
