If you look at a vertical profile of the atmosphere showing ducting potential, you can see from the photo that there is a sharp increase in temperature at the horizon, coupled with a sharp fall in dew-point at the position the image was taken. The duct occurs below the inversion and so with the clarity and colour of the image Tropospheric ducting cannot be responsible. I think you were just bullsh1tting there JJ. Like me, but it sounds good. Dunnit.
I've messed with tropospheric ducting, but only with the radio-type wireless waves. It's pretty amazing what can be achieved - although I've only experienced it by accident, not design! The last time was a few years ago when I used a little VHF (144mhz) hand-held transceiver and was chatting to a bloke in Chippenham - 150-ish miles away. S'good stuff.
Is that Blackpool tower on the left. Ha
ReplyDeleteI wondered about that myself!
DeleteI thought you meant the top photo :-)
ReplyDeleteAh, no - the giveaway is that St George's Loch in Timperley isn't quite as long as the one in the top photo!
DeleteInteresting how the refraction seems to have brought Jodrell Bank into view!
ReplyDeleteTropospheric ducting - quite common at this time of the year :-)
