GOES-16 (GOES-East) Upper-level Water Vapor (6.2 µm) (above) and Mid-level Water Vapor (6.9 µm) images (below) displayed a well defined leeside cold frontal gravity wave (reference) as it began to propagate southward from Colorado/Kansas late in the day on 11 October 2020. A bore structure eventually developed near the leading edge of the cold... Read More

Multi-spectral views from Himawari-8’s “Target Sector” that provides 2-minute imagery, above, show weakening Typhoon Chan-hom south of Japan. The Typhoon shows a sheared structure, with the surface circulation southwest of the main convection, a shift that is especially evident in the Band 5 1.61 µm channel that differentiates between low...

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Clean” Infrared Window (10.35 µm) images — with and without an overlay of GLM Flash Extent Density — and “Red” Visible (0.64 µm) images (above) showed showed Hurricane Delta as it intensified from a Category 2 to a Category 3 storm over the Gulf of Mexico during the daytime hours on 08 October 2020. Cloud-top infrared brightness temperatures of... Read More

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Clean” Infrared Window (10.35 µm) images — with and without an overlay of GLM Flash Extent Density — and “Red” Visible (0.64 µm) images (above) showed showed an impressive convective burst near the center of Tropical Storm Delta, which developed a couple of hours before the storm reached Category 1 Hurricane intensity at 0000 UTC on 06 October over the Caribbean Sea....
