AWIPS images of the GOES-12 6.5µm “water vapor” channel (above) show an upper-level low that was intensifying over Florida during the day on 18 September 2007. As warm/dry middle to upper tropospheric air (yellow enhancement) wrapped around and into the southwestern quadrant of the cyclone, convection was seen to develop along the... Read More
GOES-11 visible channel imagery (above) showed a nice example of lee wave “lenticular clouds” immediately downwind of the Spring Mountains (whose highest peak is Mt. Charleston at 11,918 ft or 3362 m) just to the northwest of Las Vegas, Nevada (Google maps) on 14 September 2007. The vertical motions associated with lee waves can cause... Read More
The color-enhanced Channel 4 GOES-12 IR image above shows a crescent-shaped region of cooler cloud tops over the upper midwestern part of the United States, stretching from extreme northeastern Kansas northeastward to eastern Lake Superior. (The blue enhancement shows cloud-top brightness temperatures around 250 K whereas the isolated pixels of... Read More
Many meteorological eyes have been watching a system in the western Atlantic during the past couple of days. This GOES-12 visible image includes a circulation near 28 N, 70 W (more easily seen in the animation above) that could be the kernel of the next tropical system in the Atlantic.There are several notable...
