1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) include time-matched plots of SPC Storm Reports — and showed severe thunderstorms associated with the landfall of Tropical Storm Claudette (surface analyses) early in the day on 19 June 2021. Numerous pulsing overshooting tops were evident with some of these storms.The corresponding 1-minute GOES-16 “Clean” Infrared Window (10.35 µm) images (below) displayed cloud-top infrared brightness temperatures as cold...

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.35 µm) images (above) showed the formation of Potential Tropical Cyclone 3 in the Gulf of Mexico on 17 Jun 2021. A low-level circulation could be seen near the storm center on Visible imagery, but deep convection was only occurring at some distance from the center.Even though... Read More

True-color imagery derived from GOES-16, above, shows a low-level cyclonic circulation associated with then Tropical Depression #2 to the east of Cape Hatteras over the western Tropical Atlantic. The satellite imagery suggests strong southwesterly shear: ongoing deep and vigorous convection is far removed to the east and northeast of the... Read More

GOES-17 (GOES-West) “Red” Visible (0.64 um) images (above) showed the development of a subtropical storm in the South Pacific Ocean (just northeast of New Zealand) on 27 May 2021. Surface analyses from the New Zealand Met Service are available here.GOES-17 “Clean” Infrared Window (10.3 um) images (below) highlighted the curved band of cold-topped convection wrapping...
