250-meter resolution Terra and Aqua MODIS true-color Red/Green/Blue (RGB) images from the SSEC MODIS Today site (above) revealed the presence of an undular bore along the leading edge of a southward-moving cold front (also known regionally as a “pneumonia front“) on
Regular readers of this blog will be quick to recognize the GOES imagery above as a low cloud detection product that exploits the differences in emissivity properties for water droplets that exist between 3.9 and 10.7 µm, two radiation bands that are detected on the GOES imager. The emissivity differences... Read More
The water vapor animation from GOES-East on March 12th shows a structure rotating through the upper-level trough, which structure looks very much like a so-called “Sting Jet”. (In the animation above, the sting jet structure crosses the Missouri/Kansas border south of Kansas City, propagates across northern Missouri and eastern Iowa... Read More
A sequence of AWIPS images of POES AVHRR 0.86 µm visible channel data (above) showed the areal extent of ice in the Bering Sea during the 09 March – 11 March 2012 period. The far southern edge of the ice could be seen moving a bit further to the south during... Read More
