Another name for them is PSCs, for Polar Stratospheric Clouds. We’ve been seeing them at Palmer for the past month. They’re here almost every winter, but I don’t know that they’ve ever been seen this early (last year the first sighting was Sept 19th).

Yahoo News from the big wire services had the info wrong though. Newspapers up in the States converted the temperatures incorrectly on the radiosonde readings and also the temps needed for the clouds to form. Correct Info and story was originally from http://www.aad.gov.au/default.asp?casid=23042 http://www.aad.gov.au Author Posts Viewing 4 posts - 1 through 4 (of 4 total) The forum ‘Science and Weather’ is closed to new topics and replies.
