The other night a BBC weather reporter was talking about exceptionally high temperatures observed in the North East (mainly scottish hills, I think). Sorry I can't be more precise, but I can't find any mention of it on the old interweb.
He was discussing a fascinating cycle whereby warm air rises up hillsides at one temperature, and then warms again on the descent due to the "fern effect". Resulting in up to 5 degree increases in air temperature, and temperatures approaching seasonal records - around 17 degrees.
It's a shame I can't find more information about it. I generally find BBC weather forecasts horrendously tedious, but this was rather interesting. |
