A strong “Alberta Clipper” system ushered in some of the coldest air of the 2008/2009 winter season on 12 January 2009 — in fact, it was so cold that AWIPS images of the GOES-12 10.7 µm IR channel data (above) showed that surface brightness temperatures as cold as -20º to -40º C... Read More
AWIPS images of the GOES-12 6.5 µm water vapor channel data with an overlay of polar-orbiting QuikSCAT winds (above) showed the a rapidly-occluding cyclone over the Labrador Sea on 07 January 2009. The classic “dry swirl” signature on the water vapor imagery is a tell-tale indicator that a mature cyclone has reached... Read More
A potent shortwave trough was propagating eastward across the Upper Midwest region on 29 December 2008, and AWIPS images of the GOES-13 6.5 µm “water vapor channel” (above) showed a well-defined signature of mid-level dry air (yellow colors) moving rapidly east-southeastward over... Read More
