It’s a nice skyfull of altocumulus, but neither that or the row of Leeds chimmney pots are the reason why I did battle with the camera app on my new smartphone. What caught my eye was the contrail, and the vortex rings which seemed to be dropping off its lower edge. Unfortunately, the camera didn’tContinue reading Contrails and smokerings
I have just finished the lectures on how light and infra-red radiation affect the weather as part of one of our introductory meteorology courses. It is pleasing when nature throws you a nice example at the right time. It is always hard to get over the point that the long-wave thermal infra-red radiation is importantContinue reading Looking at the sky (and the ground)

We’re all supposed to be keen on blogging, they keep telling me.

And the most exciting thing to happen in thatContinue reading The joys of internet shopping
