Artificial clouds

Some people start sniggering when they hear the term 'chemtrails', and happily dismiss it as one of those crazy conspiracy theories. "Where's the evidence?" they might ask. Although some people have analysed soil and rainwater samples to prove the existence of things that don't usually float in our atmosphere, like Aluminium, Barium and Strontium, and sometimes even weird biomaterial like desiccated red blood cells, as long as the main stream media doesn't pick up on it, it can't be real.

But it's easy to observe inexplicable celestial phenomena, usually dismissed as 'contrails'. Anyway, today weather radar above Melbourne showed something I challenge anyone to explain as 'natural phenomenon'. The pictures below show this afternoon's weather radar. Pretty much in the center of all images are four parallel 'clouds', that begin as thin lines and slowly morph into less suspicious, cloud like shapes.

I think it's quite safe to assume that those lines of the radar were artificially created. However, I'm open to any explanation how these parallel constellation might have occurred naturally. When I've got some more time, I might make any animation out of these.
