Minutes of the January 30, 2012 Meeting
Smoky Mountain AMS Chapter
The January meeting of the AMS Smoky Mountain Chapter was held on the University of Tennessee Ag campus in our usual meeting room in the BEES building. Around thirteen people met first for dinner at the Calhoun's on the River restaurant, and then twenty-five members convened on the UT Ag campus to hear Grant Goodge speak about "Arcs, bows, halos, and other optical phenomena". Grant is a retiree of NOAA's National Climatic Data Center, but continues on contract to NOAA in monitoring the Climate Reference Network. Grant's presentation focused on visual arcs and halos created by the refraction and reflection of light through raindrops, cloud droplets, ice crystals, and strong temperature inversions that produce mirages. He used numerous photos from his own collection as examples of these various phenomenon. The last subject of his presentation centered on the subject of the aurora and the coronal mass ejections that create them. Also discussed was the significant damage and interference to electrical systems that these solar storms have caused in the past and pose in today's more electronically dependent infrastructure.
Dale Kaiser also talked about his trip to the national AMS annual meeting in New Orleans, where he presented a poster displaying the Smoky Mountain Chapter's 2011 activities. This poster won second place at the AMS Annual Meeting Chapter Poster Competition.
