how can you describe its "eye"?
The eye is normally circular and is typically in diameter, though eyes as small as and as large as have been observed.
Tropical cyclone
 The eye is normally circular and is typically in diameter, though eyes as small as and as large as have been observed.
cyclonic storms can form within or between air masses UNANSWERABLE what are its surface-based types? Extratropical cyclones, Subtropical cyclones and Tropical cyclones what is the first one? They are sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth how is it formed? Extratropical cyclones form anywhere within the extratropical regions of the Earth, either through cyclogenesis or extratropical transition. what can you tell about its vertical structure? Extratropical cyclones slant back into colder air masses and strengthen with height, sometimes exceeding 30,000 feet (approximately 9 km) in depth. what is meant by the third type mentioned above? It is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain or squalls. how is it related to climate change? Climate change can affect tropical cyclones in a variety of ways: an intensification of rainfall and wind speed, a decrease in overall frequency, an increase in frequency of very intense storms and a poleward extension of where the cyclones reach maximum intensity are among the possible consequences of human-induced climate change. and how it is related to popular culture? In popular culture, tropical cyclones have made several appearances in different types of media, including films, books, television, music, and electronic games.

Tropical cyclone [SEP] Eye and center
At the center of a mature tropical cyclone, air sinks rather than rises. For a sufficiently strong storm, air may sink over a layer deep enough to suppress cloud formation, thereby creating a clear "eye". Weather in the eye is normally calm and free of clouds, although the sea may be extremely violent. The eye is normally circular and is typically in diameter, though eyes as small as and as large as have been observed. The cloudy outer edge of the eye is called the "eyewall". The eyewall typically expands outward with height, resembling an arena football stadium; this phenomenon is sometimes referred to as the "stadium effect".
