Description given on Youtube:
Another odd image appears on the Australian weather map. This is centred around a radar known area, BlackJack Mountain situated in New South Wales. Odd thing is, it seems to have BOM also trying to work out what this cause is, as they have a print, on the page saying:
“If you notice any circular patterns or straight lines originating from the centre of the radar location, this is due to occasional interference to the radar data. The Bureau is currently investigating ways to reduce these interferences.”
This is the 2nd odd sighting i have viewed in about 1 week.
Does anyone have an explanation as to what these might be?
