The potent cyclone (surface analysis, an airmass RGB animation from the College of Dupage website is below) that caused severe weather over Hawaii (blog post) is also drenching the islands with considerable rains. The animation of MIMIC Total Precipitable Water, above, shows the storm drawing tropical moisture northward from the Intertropical Convergence Zone. The airmass RGB,... Read More

Geo2grid software accesses SatPy libraries that allow for the reading of level-1c netcdf files holding FCI (Flexible Combined Imager) data from the latest operational Meteosat satellite (Meteosat-12). So if you can access to that output, you can create beautiful images as the ones shown above. The RGB shows a storm... Read More

Night Microphysics RGB imagery from the CSPP Geosphere site (link) show the blossoming of high clouds (deep red in the RGB) north of the Samoan Islands, clouds that subsequently sag southward. Careful inspection of the animation also shows clouds that are more pink than deep red; these are likely mid-level... Read More

GOES-18 Upper Level water vapor infrared imagery, above, (source) shows a stream of upper-level moisture moving over southeastern Alaska on the east side of a cyclonic system over western Alaska on 27 January 2025. This large storm moved warm and moist air northward into Alaska; several stations tied record warm... Read More
