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...
