JMA Himawari-8 “Red” Visible (0.64 µm), Shortwave Infrared (3.7 µm) and Infrared Window (10.3 µm) images (above) showed the development of a pyroCumulonimbus (pyroCb) cloud from a bushfire that was burning in the eucalypt forests of eastern Victoria, Australia on 25 January 2019. A rapid-scan “Target” sector was positioned over... Read More

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and Near-Infrared (1.61 µm) images (above) displayed a long plume of horizontal convective roll (HCR) clouds across parts of the Upper Midwest on 24 January 2019. These HCR cloud features formed in the presence of strong northerly/northwesterly boundary layer winds in the wake of a cold frontal passage... Read More

With a ridge of high pressure in place over the western Atlantic Ocean, GOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images (above) indicated the presence of dry air within the middle troposphere off the Southeast US coast on 23 January 2019.GOES-16 “Red” Visible (0.64 µm) images showed that marine boundary layer stratocumulus clouds covered much...

A large central/eastern US winter storm impacted much of the Northeast with rain, snow, freezing rain/drizzle and strong winds on 20 January 2019 (surface analyses) — and a post-storm comparison of GOES-16 (GOES-East)  “Red” Visible (0.64 µm) and Near-Infrared “Snow/Ice” (1.61 µm) images on 22 January (above) revealed a dark 1.61 µm signature (often indicative of significant ice accrual)...
