What is "stadium effect" in the eye of Hurricane Dorian?

In mission, the NOAA 42 combat aircraft captured the first images of the interior of Hurricane Dorian, where we could clearly see the "stadium effect" formed by the clouds.

The National Oceanic and Atmospheric Administration (NOAA) Air Operations Center posted on its official Twitter account the images taken on 1 September from the eye of Cyclone Dorian, where its destructive power is appreciated, although Inside, there is a relative calm.

The images captured by the NOAA 42 were taken from a fighter plane. It is also known that NOAA again sent another fighter jet, the Lockheed WP-3D Orion, but on this occasion, it was intended to take Dorian, which is currently in category 5 of Saffir-Simpson.

This "staging effect" occurs when the clouds in the eye wall, the area where the winds and the strongest storms meet, are curved in the shape of a cone.
However, in the case of tropical hurricanes, their eyes are very small and the stadium effect is more pronounced than other cyclones, but they have the same structure, they are larger at the top of the storm and smaller at low. .
