GOES-18 airmass RGB imagery, above (created using geo2grid software), shows the development of a hurricane-force low to the west of Washington and Oregon on the 19th of November. The orange and purple colors in the RGB suggest a significant intrusion of stratospheric air. That air is rich in ozone, and... Read More
5-minute CONUS sector GOES-16 (GOES-East) Red Visible (0.64 µm) images (above) displayed an intensifying Hurricane Force low pressure system over the western Atlantic Ocean (not far off the North Carolina coast) on 15 November 2024. Note the area of haziness just west-southwest of the center of the surface low — this milky/hazy appearance was... Read More
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
1-minute Mesoscale Domain Sector GOES-18 (GOES-West) Visible and Infrared imagery of Hurricane Kristy in the East Pacific Ocean on 23 October (above) highlighted a well-defined eye, with GLM-indicated lightning activity increasing within the inner eyewall. Cloud-top infrared brightness temperatures in the -80s C (shades of violet to purple) were apparent at times.... Read More
