GOES-16 (GOES-East) Near-Infrared “Snow/Ice” (1.61 µm) images (above) displayed industrial plumes (from sources such as power plants) that produced brief periods of light snow as they drifted over a few sites in northern Wisconsin on 22 January 2023. Particles emitted from industrial stacks acted as cloud condensation nuclei, “seeding” the surrounding supercooled water cloud... Read More

A sequence of GOES-16 (GOES-East) “Red” Visible (0.64 µm), Day Cloud Phase Distinction RGB and Day Snow-Fog RGB images (above) showed widespread fog/stratus across parts of Montana, North/South Dakota and Minnesota during the day on 06 January 2023. With a quasi-stationary area of high pressure located over that area (surface analyses), winds remained light and the fog/stratus layer was slow... Read More

GOES-17 — and GOES-18, beginning at 1801 UTC on 04 January (after GOES-18 became the operational GOES-West satellite) — Air Mass RGB images (above) showed a rapidly-intensifying Hurricane Force low pressure system (surface analyses) over the East Pacific Ocean as it approached the US West Coast during the 03 January – 04 January 2023 period...

A sequence of GOES-16 (GOES-East) Nighttime Microphysics RGB and Day Snow-Fog RGB images (above) showed plumes of “ocean effect” clouds (including a “sound effect” cloud band, originating over Long Island Sound) that produced periods of snowfall from coastal Connecticut and Rhode Island (as well as Block Island) to Martha’s Vineyard, Nantucket Island and Cape...
