what is the structural implication of this?
A large "ragged eye" is a non-circular eye which appears fragmented, is an indicator of a weak cyclone. An "open eye" is an eye which can be circular, indicates a weakening cyclone.
Eye (cyclone)
While normally quite symmetric, eyes can be oblong and irregular, especially in weakening storms. A large "ragged eye" is a non-circular eye which appears fragmented, and is an indicator of a weak or weakening tropical cyclone. An "open eye" is an eye which can be circular, but the eyewall does not completely encircle the eye, also indicating a weakening, moisture-deprived cyclone. Both of these observations are used to estimate the intensity of tropical cyclones via Dvorak analysis. Eyewalls are typically circular; however, distinctly polygonal shapes ranging from triangles to hexagons occasionally occur.
how many miles is the eye of a hurricane It is approximately between 20–40 miles. what is the eye (cyclone)? It is a region of mostly calm weather at the center of strong tropical cyclones. It is a roughly circular area and is surrounded by the a ring of towering thunderstorms.

Eye (cyclone) [SEP] Structure
While normally quite symmetric, eyes can be oblong and irregular, especially in weakening storms. A large "ragged eye" is a non-circular eye which appears fragmented, and is an indicator of a weak or weakening tropical cyclone. An "open eye" is an eye which can be circular, but the eyewall does not completely encircle the eye, also indicating a weakening, moisture-deprived cyclone. Both of these observations are used to estimate the intensity of tropical cyclones via Dvorak analysis. Eyewalls are typically circular; however, distinctly polygonal shapes ranging from triangles to hexagons occasionally occur. While typical mature storms have eyes that are a few dozen miles across, rapidly intensifying storms can develop an extremely small, clear, and circular eye, sometimes referred to as a "pinhole eye".
