The hindwing upperside has a well-defined orange-beige median band, including a series of vein dots.

Although thunderstorm activity was initially minimal around the center of circulation, the depression had a well-defined convective band.

Hours later well-defined curved bands and an improving circulation at the surface warranted that the system be designated a tropical depression.

It developed well-defined curved bands and briefly exhibited an upper-level eye feature.

Convection gradually became better organized, with a well-defined band in its eastern semicircle and intermittent thunderstorm activity near the center.

Its coloration can be black or sometimes dark brown; often there are well-defined bands of bright and dull material within the seams.

On October 8, the wind shear relented and a well-defined band persisted near the storm's center of circulation.

Juliette quickly organized with a well-defined band of convection drawn into the circulation.

Satellite imagery late on September 3 showed a well-defined curved band wrapping around much of the circulation.

Moreover, a prominent feature in the gel retardation experiments is the presence of a smear between the two well-defined bands.
