1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) and “Clean” Infrared Window (10.3 µm) images (above) showed thunderstorms that produced 7 tornadoes, hail as large as 2.00 inch in diameter and damaging wind gusts across southern Wisconsin (SPC Storm Reports) on 22 June 2024. The Infrared images revealed pulses of thunderstorm overshooting tops that exhibited 10.3 µm brightness temperatures as cold as -75ºC (brighter... Read More

Geosphere true-color imagery over the Atlantic Ocean to the east of Florida and Georgia, above, shows a low-level cyclonic circulation with strong convection to its south. The appearance of the system suggests strong shear; an analysis of shear from the SSEC Tropical Weather website, below, shows the northerly shear over the storm... Read More

MIMIC Total Precipitable Water fields from 15 June through 19 June 2024, above, show a broad cyclonic circulation over Central America and adjacent waters (the Central American Gyre). On 18 June, shown below in an animation from the CSPP Geosphere site, the convection in this gyre was diffuse and unorganized (although the... Read More

GOES-18 imagery over California at 1836 UTC (above, left) show a very strong signal over San Luis Obispo County: very bright in visible imagery and warm in the shortwave infrared. In the GOES-16 imagery, that signal is not present. In contrast, the warm signal in the shortwave infrared in GOES-18... Read More
