Not strictly weather related but just had a very strange experience here.
For the last 10 minutes, and very deep 'droning' sound was heard outside, so deep in fact, that the chair I was sitting on vibrated. Went outside, as did others in the street, and the sound clearly was coming from the sky, but such was the nature of the sound, it was hard to pinpoint a specific point. The sound itself was constant, but the deeper sounds came in specific 'waves'. I am sorry I wasn't quick thinking enough to record it but it was very weird and very very eerie.
Anyone any ideas? Is the current state of the atmosphere making the sound of ordinary jets sound stranger than they normally would be? or have the Russians decided to go all out?? I jest of course but this was no normal aircraft sound.
