What are the three parts of a hurricane and how do they contribute to the overall structure and intensity of the storm?

A hurricane consists of three main parts: the eye, the eyewall, and the rainbands. The eye is a calm, clear center surrounded by the eyewall, which contains the strongest winds and heaviest rainfall. The rainbands are bands of clouds and thunderstorms that spiral outward from the eyewall. These three parts work together to maintain the storm's structure and intensity, with the eyewall acting as the powerhouse of the hurricane and the rainbands helping to feed energy into the system.
