An anomalousy deep extratropical storm or “Kona Storm” north of Hawai`i (surface analyses) brought strong winds and heavy rainfall to much of the island chain during the 18-20 December 2022 period. GOES-17 (GOES-West) Air Mass RGB images (above) showed the core of the storm (darker shades of orange-red) as well as widespread thunderstorms along and ahead of the... Read More

A sequence of 1-minute Mesoscale Domain Sector GOES-16 (GOES-East) images from all 16 ABI spectral bands along with Rocket Plume RGB images (above) displayed signatures of the launch of EUMETSAT MTG-I1 from the Guiana Space Centre near Kourou, French Guyana (synoptic station identifier 814030) on 13 December 2022. The Ariane-5 rocket booster’s hot thermal... Read More

GOES-16 (GOES-East) Air Mass RGB images (above) showed the signature of dry air (brighter shades of orange-red, which also indicate the presence of a lower tropopause with higher levels of stratospheric ozone within the atmospheric column) wrapping into the circulation of an anomalously-deep Hurricane Force low pressure system — which had recently...

GOES-16 (GOES-East) Nighttime Microphysics RGB and Day Snow-Fog RGB images (above) showed a lake effect fog/stratus plume that was meandering slowly northward from the still-unfrozen Fort Peck Lake in northeastern Montana (just south of Glasgow) on 08 December 2022.During the hours leading up to sunrise, GOES-16 Nighttime Microphysics RGB images with an overlay of the GOES-16 Cloud Top Phase derived...
