A weak, isolated tornado developed in southwestern Minnesota during the afternoon of 11 August 2010. GOES-15 imagery, above, shows the development of modest cumulus convection that spawned the tornado. The 5-minute time-step in the imagery is similar to that that will be available routinely from the ABI on GOES-R; the loop was taken... Read More
(Click image for larger version)GOES-15 is observing from a vantage point above the Equator at 89.5 W and GOES-13 is observing from a vantage point above the Equator at 75 W. The two satellites therefore have slightly different perspectives of cloud scenes over the southeast United States. These different perspectives... Read More
The image loop above shows GOES-15 11-micron imagery every half hour as Tropical Depression #4 in the Atlantic strengthened to become a minimal Tropical Storm, gaining the name Colin in the process. The infrared imagery shows periodic bursts of convection with brightness temperatures colder than -70 C near the center... Read More
Severe thunderstorms propagated southeastward across far northeastern Montana late in the day on 26 July 2010. McIDAS images of GOES-11 (GOES-West), GOES-15, and GOES-13 (GOES-East) 10.7 µm IR data (above; each image set is displayed in the naive projection of the respective satellite) showed that a subtle “enhanced-v” storm top signature first...
