GOES-18 images shown in this blog post are preliminary and non-operationalGOES-18 Mid-level Water Vapor (6.9 µm) images during the 18 July – 19 July 2022 period (above) showed a series of impulses rotating within the broader circulation of an anomalously-deep low pressure system that meandered over the Bering Strait region. Anomalously-cold air... Read More
GOES-16 (GOES-East) “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm) and “Clean” Infrared Window (10.35 µm) images (above) showed that a large wildfire burning in far western Manitoba produced a series of 3 brief pyrocumulonimbus (pyroCb) clouds late in the day on 19 July 2022. The coldest pyroCb cloud-top infrared brightness temperature was -52.1ºC at 0230 UTC.GOES-18 images... Read More
GOES-18 images shown in this blog post are preliminary and non-operational Overlapping 1-minute Mesoscale Sectors provided 30-second images of GOES-18 “Red” Visible (0.64 µm) data, which showed the circulation of a Mesoscale Convective Vortex (MCV) that moved northward across southern Nevada early in the day on 17 July 2022. Ongoing thunderstorms along the periphery... Read More
GOES-18 images in this blog post are preliminary and non-operational Overlapping 1-minute Mesoscale Domain Sectors provided GOES-18 “Red” Visible (0.64 µm) images at 30-second intervals (above), which include time-matched SPC Storm Reports. This imagery showed widespread thunderstorms that moved eastward across Montana on 09 July 2022, which produced damaging straight-line winds as strong as 78... Read More
