Hi folks, need some help on interpreting a radar phenomenon here. When I awoke this morning I checked the ILM radar to see if the relatives were going to get any wet weather this morning at Long Beach, NC, and I noticed something odd - a circle of data formed and expanded east of the radar (near Wilmington). I dismissed it as chance until I saw similar things taking place in various areas in the Carolinas and in fact all over the Southeast, according to the WSI Regional, and none of them were centered on the radar like bad data usually is. I've seen many a funny thing on radar, from ground clutter to anomalous propagation to mountains, birds, gust fronts, you name it. But I hadn't seen this before today. Please check out the following page where I have posted some loops of the images and let me know if you can explain this phenomenon. I will also be asking on the weather newsgroups. Thanks. The best example (GSP this morning) loads on the page, and there are links to other sites and other radar products (r1,r2,r3,r4,v1,cr). I also have some individual products from 10:58Z for GSP and the stills of all the animations if you need them. Notice on the GSP an "explosion" to the SE, WSW, and NE of the radar. These are what I am talking about. In the "regional" directory, the first image shows the WSI Regional which shows a number of these circles throughout the SE US (although WSI's Quality Control Program wiped some of them out). http://www.weatherwatchers.org/temp/radarwhat/ -- ============================================================== Jesse Ferrell - Meteorologist/Web Dev. - j{at}weatherwatchers.org Central Atlantic Storm Investigators - www.weatherwatchers.org "A tornado?
