Chewbalka Posted October 30, 2012 Report Posted October 30, 2012 I noticed something very similar to this just not as pretty on the weather network directly above riding mountain national park periodically throughout the summer... But i just dismissed it as a mistake or damaged weather station... Nothing was going on in the park so i am assuming it was nothing important. The pictures shown in mexico are much prettier though, they were kinda just straight lines in a circle pattern here. Quote
CraigD Posted October 30, 2012 Report Posted October 30, 2012 The linked-to YouTube video states that the image appeared briefly on a The Weather Chanel website. The legend shows that it is intended to indicate rainfall. Various paranormal and conspiracy theory forums note that no precipitation was measured in the parts of Mexico where the image indicates heavy rainfall was occurring, so this video appears to capture some sort of RADAR imaging system malfunction. I’ve seen wispy spiral patterns in old non-computerized airborn RADAR system, which I understood to be an artifact common to interference from similar RADAR systems on nearby aircraft. A quick google search finds an illustration and text matching my recollection in this 1990 RADAR and ARPA manual. My guess is that the much more sophisticated computerized RADAR image generating systems used to provide realtime precipitation maps like The Weather Chanel’s also exhibit this spiral pattern, but with much more dramatic and colorful artifacts. A professional familiar with these systems could likely shed more light on the subject, but as most discussion of it appears to be among the paranormal and conspiracy theory community, which I doubt would be very friendly and accepting of comments from such folk, I’d be surprised if any bothered posting. Maybe we’ll get lucky, and an expert will post something here. Turtle and belovelife 2 Quote
belovelife Posted October 30, 2012 Author Report Posted October 30, 2012 still looking for more ways to get the data from that day, having a difficult time? Quote
belovelife Posted November 3, 2012 Author Report Posted November 3, 2012 does anyone know anyone who might be able to get the original radar ? Quote
LaurieAG Posted November 19, 2012 Report Posted November 19, 2012 It's obviously an artefact of the generation of the composite CGI because the pattern only appears in the circle of the combined radar image and not elsewhere. Similar linear artefacts appear like lighthouse beams in otherwise clear skies. Quote
LaurieAG Posted November 19, 2012 Report Posted November 19, 2012 (edited) I just captured those two images above and, considering that the wind directions are indicated at the various weather stations, the overall doppler image appears to be off center and skewed towards the left/west side.
