A sequence of Suomi-NPP VIIRS Day/Night Band (0.7 µm) and Infrared Window (11.45 µm) images (above) showed the cyclonic swirl of clouds associated with a low pressure system that was moving eastward across the Beaufort Sea on 25 October 2024. The relatively tight pressure gradient south of this low (surface analysis)... Read More
High Pressure over the Great Lakes on 25 April meant a spectacular true-color view of the 5 Great Lakes (apologies to Lake Champlain) by the VIIRS instruments on NOAA-20. A similar view was recorded at 1755 UTC by Suomi-NPP, shown below.Clear skies also meant a determination of Lake Surface Temperatures, shown below (compare these to Monday,... Read More
Altimetric measurements of the sea surface (from this site), above, show a region of very tall waves early on 14 February, with Significant Wave Heights exceeding 30 feet. Those waves are also show below in an analysis from OPC (link); they are southwest of a hurricane-force low (surface analysis; here is a toggle between the Significant Wave... Read More
GOES-18 (GOES-West) and GOES-16 (GOES-East) True Color RGB images from the CSPP GeoSphere site (above) showed hazy plumes of blowing dust lofted by Tehuano gap winds that emerged from the south coast of Mexico — which spread out across the Gulf of Tehuantepec and the adjacent waters of the Pacific Ocean on 27-30 January 2024 (long, narrow rope...
