20 March 1998 -- GOES-8 10.7 Micron Longwave IR
F3 Tornado in Northern Georgia
(this 9-image Java animation sequence will take a minute or two to load...)
This 4-hour loop of 30-minute GOES-8 10.7 micron longwave IR imagery shows the rapid re-intensification of convection along the trailing edge of a collapsing squall line over northern Georgia. A core of cold cloud top temperatures (-51 to -54 C, yellow enhancement) began to appear with the developing convection around 09:45 UTC.
Surface wind barbs are plotted in red for the times closest to that of each image. The surface wind over northeastern Georgia backs from southwesterly to southeasterly as the developing convection approaches. With stronger southwesterly mid-tropospheric winds advancing over the region, a wind profile with low-level veering and increasing speed with height was created.
