Another Pembrokeshire Dangler

Posted in Cardiff with tags , , on October 29, 2018 by telescoper

Taking the opportunity of  the Irish Bank Holiday Monday to spend a long weekend in a rather chilly Cardiff,  I find that Wales is once again under the influence of a Pembrokeshire Dangler:

The Northerly airflow that is responsible for this phenomenon (which I first encountered last year)  is causing a bit of a cold snap here in Cardiff, and has even brought snow to  parts of Wales,  but hopefully the Pembrokeshire Dangler will not interfere with my flight back to Ireland.


Vector Calculus Weather

As it happens I did a lecture today about vector fields as part of my module on vector calculus. Whenever I did similar lectures in the past I used the day’s weather map as an illustration, so this morning I downloaded what turned out to be a particularly dramatic example. The curl of the velocity field around the weather system off the west coast of Ireland this morning was definitely non-zero…

Storm Callum turned out to be not as damaging as feared. Apparently it was rather windy in Maynooth overnight, but I slept right through it.

The Beast From The East

From my viewpoint in sunny snow-free Cardiff I can only assume that all this talk of The Beast From The East means that Nikolai Valuev is about to make a comeback to the boxing ring.

Standing a mighty seven foot tall, Valuev is the heaviest and tallest man ever to have been a world boxing champion. He retired from the ring on 2009, but I think he’d still be capable of surviving a few inches of snow…

The Pembrokeshire Dangler

They say there’s a first time for everything, and it turned out yesterday was the first occasion on which I encountered a Pembrokeshire Dangler:

It’s still there today. The Northerly airflow that is responsible for this phenomenon is causing a very cold snap here in Cardiff, but hopefully the Pembrokeshire Dangler will not hang around much longer.

In Thunder, Lightning and in Rain..

A while before 6am this morning I was woken up by the sound of fairly distant thunder to the West of my flat. I left the windows open – they’ve been open all the time in this hot weather – and dozed while rumblings continued. Just after six there was a terrifically bright flash and an instantaneous bang that set car alarms off in my street; lightning must have struck a building very close. Then the rain arrived. I got up to close the windows against the torrential downpour, at which point I noticed that water was coming in through the ceiling. A further inspection revealed another leak in the cupboard where the boiler lives and another which had water dripping from a light fitting. A frantic half hour with buckets and mops followed, but I had to leave to get to work so I just left buckets under the drips and off I went into the deluge to get soaked.

Here is the map of UK rain at 07:45 am, with Brighton in the thick of it:


I made it up to campus (wet and late); it’s still raining but hopefully will settle down soon. This is certainly turning into a summer of extremes!

Sleep well last night?

We had a spectacular thunderstorm over Brighton last night. I do love a good thunderstorm. Although I enjoyed the show, I didn’t get much sleep. Judging by the following graphic from BBC Weather, I’m not the only one…
