A sequence of 1-minute Mesoscale Domain Sector GOES-16 (GOES-East) Dust RGB and Mid-level Water Vapor (6.9 µm) images (above) showed the development of dense plumes of blowing dust (whose source regions were primarily in southeast Colorado and the Oklahoma/Texas Panhandles) on 15 December 2021. These dust plumes were being lofted by strong winds along and behind a cold... Read More
1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Clean” Infrared Window (10.35 µm) images (above) include time-matched plots of SPC Storm Reports during a large outbreak of severe weather across parts of the Midwest and Southeast US from late in the day on 10 December to a few hours after midnight on 11 December 2021. The severe thunderstorms developed in advance of a strong... Read More
As an anomalously-deep Kona low moved northwest of and then west of Hawai`i during the 04-07 December 2021 period, it began to tap moisture from the Pacific ITCZ and channel it northward across the islands — setting the stage for a prolonged heavy rainfall event (which produced the wettest December day on record at Honolulu). Hourly MIMIC TPW images viewed... Read More
GOES-16 (GOES-East) Near-Infrared “Snow/Ice” (1.61 µm) images (above) showed the shadow of a total solar ecliipse in the Southern Hemisphere on 04 December 2021. Even though the 1.61 µm imagery is at a lower (1 km) spatial resolution, it provided better contrast than higher-resolution (0.5 km) 0.64 µm “Red” Visible imagery, helping to highlight... Read More
