GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) showed that most of Antarctica experienced 24 hours of full solar illumination during the Southern Hemisphere’s Summer Solstice on 21 December 2019. Through breaks in the cloud cover, a few bright areas of sun glint were also evident, moving from west to... Read More
A comparison of GOES-17 (GOES-West) Nighttime Microphysics RGB and “Clean” Infrared Window (10.35 µm) images (above) showed the formation and motion of patchy stratus clouds (RGB shades of yellow) over Interior Alaska on 17 December 2019. Note how the clouds are difficult to detect and track on the 10.35 µm images, since the... Read More
1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) showed thunderstorms that produced a variety of severe weather (SPC Storm Reports) across the Deep South on 16 December 2019. Numerous overshooting tops could be seen with these storms.GOES-16 “Clean” Infrared Window (10.35 µm) images (below) indicated that many of the overshooting tops exhibited brightness temperatures...

As a strong 170-knot jet streak (Satellite Liaison Blog) flowed southeastward over the High Plains on 13 December 2019, GOES-16 (GOES-East) Mid-level (6.9 µm) Water Vapor images (above) showed numerous pilot reports of moderate to severe turbulence at altitudes of 26,000-50,000 feet. The Turbulence SIGMETs were issued due to strong speed shear along the poleward... Read More
