A QuickTime animation of GOES-12 imager 6.5 micrometer (“water vapor channel”) imagery (above) reveals an interesting vortex associated with a cutoff upper-level low which was migrating eastward from Illinois to Ohio on 13 Sepember. Several pulses of convection can be seen developing along the periphery... Read More
A large (208,000 acre) wildfire continued to burn near Derby Mountain in southwestern Montana on 12 September. A QuickTime animation of the 3.9 micrometer shortwave IR imagery from GOES-11, GOES-12, and GOES-13 (above) shows the “hot spots” associated with this fire — on the... Read More
