A friend of mine took this image today whilst looking north from Burghead harbour across the Moray Firth towards what looks like the cliffs around Helmsdale in Sutherland, although I could be wrong. It looks like …
It’s no wonder that we are seeing snow showers in May across the north of Scotland after looking at this mornings 11 UTC ascent from Lerwick. The 1000-500 hPa thickness at that time was just 517.5 …
There is an upper trough that’s pushing up across the Midlands at the moment, that’s spinning this interesting vortex of rain northwestward. It’s obviously now a relaxing feature, and it’s not really visible as a cut-off …
In the last week a rare hole has been noticed in the ozone layer above the Arctic. This year the polar vortex has been stable across the Arctic with record breaking low temperatures in the atmosphere …
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 …
Where has all today’s upper cloud come from? Part II Read More »
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 …
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.
A more detailed look at the midnight ascent from Yarmouth Nova Scotia where the wind was blowing 201 knots (231 mph) at 250 hPa.
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.
Can these observation from Cairnwell be believed?
