After finally seeing the back of that old cold front I never expected to see showers following on so quickly behind during this afternoon.
For those are vaguely interested by the high cloud that invaded the skies across the UK yesterday, I did finally manage to track down a Watnall (Nottingham) ascent. As far as I can see the auto-sonde ascent at 11 UTC didn’t happen, or perhaps it did, only for...
I can’t quite understand where a lot of today’s upper cloud seems to have come from across the UK. The laser cloud base recorders [LCBR] don’t seem to be able to pick it up and none of the SYNOP observations from across the country are reporting it. I...
In any other year this would have been a named storm in it’s own right, the only reason it isn’t is because its north and not south of the border.
Another 228 mph jet stream exactly a week after the last one.
A more detailed look at the midnight ascent from Yarmouth Nova Scotia where the wind was blowing 201 knots (231 mph) at 250 hPa.
Something of interest even on a cloudy day.
It’s not surprising that the high cloud has spread south so rapidly in the last few hours as there was a 150 knot northerly jet at midnight down across the country.
I don’t know the exact technical term for this ‘shield’ of cloud is, other than calling it jet stream cirrus but I know its a harbinger of rapid development. I quite like shield of cloud that I’ve coined, who knows perhaps it’ll catch on.
Another daft idea that may well come to nothing.
In the shape of an upper cold pool off the Brest peninsula maybe.
Can these observation from Cairnwell be believed?
