An AWIPS image of the MODIS 6.7 µm “water vapor channel” with an overlay of surface pressure and surface fronts (above) showed a large occluded cyclone off the New England coast on 09 May 2011. McIDAS images of GOES-13 6.5 µm water vapor channel data (below; click image to play... Read More

The “spinning globe” satellite image montage (above; click image to play animation) showed the cloud formations around the planet on Earth Day (22 April 2011). This product is created by combining data from 5 of the currently operational geostationary orbiting meteorological satellites (GOES-East at 75º West longitude, GOES-West at 135º... Read More

Water vapor imagery from Monday 4 April 2011 over the Gulf of Alaska shows the development of what appears to be Kelvin-Helmholtz instability, an instability that occurs in regions of strong shear. In this case, the shear zone occurs within a gradient of moisture along the edge of a polar... Read More

  AWIPS images of 1-km resolution GOES-13 0.63 µm visible channel data (above; click image to play animation) revealed the formation of convergence bands withing a weak cyclonic circulation over western Lake Superior on 07 March 2011. These convergence bands were responsible for producing... Read More
