The GOES-14 satellite was in Super Rapid Scan Operations for GOES-R (SRSOR) mode, providing images at 1-minute intervals over the southeastern US on 21 August 2014. An animation of 0.63 µm visible channel images (above; click to play YouTube movie) showed the development of numerous large thunderstorms, many of which were focused along surface boundaries such as the sea breeze and  convective outflow boundaries from adjacent storms.

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).
