1-minute interval GOES-14 SRSO-R visible images (above; click to play MP4 animation; also available as a 130 Mbyte animated GIF) showed the eye and surrounding cloud structure of Category 2 Hurricane Danny on 21 August 2015. The hazy signature of a dust-laden Saharan Air Layer (SAL) could be seen to the west, northwest, and north of the storm.

The compact circulation of Danny remained fairly “isolated” from the multiple pockets of SAL which stretched westward across much of the tropical Atlantic Ocean (above). The relatively clear dust-free air surrounding Danny was tropical moisture being wrapped northward into the circulation from the Intertropical Convergence Zone (ITCZ), as seen with the MIMIC Total Precipitable Water product (below).

A close-up view of Hurricane Danny (below; click image to play MP4 animation) showed some interesting detail in the convective bursts within the eyewall region, in spite of the very oblique satellite viewing angle. There is also a large (165 Mbyte) animated GIF available here.
