GOES-15 0.63 µm visible channel images (above; click image to play animation; also available as an MP4 movie file) revealed the presence of mesovortices within the eye of Category 1 Hurricane Lowell in the East Pacific Ocean on 21 August 2014.

The mesovortices were also evident at 21:07 UTC in a Suomi NPP VIIRS true-color image from the SSEC RealEarth web map server (below).

In addition to having a rather large eye, Hurricane Lowell also had a large radius of strong winds, as seen on a comparison of a GOES-15 0.63 µm visible image and Metop ASCAT surface scatterometer winds from the CIMSS Tropical Cyclones site (below).
