Vector Calculus Weather

Posted in mathematics, The Universe and Stuff with tags , , on October 12, 2018 by telescoper

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

Posted in Sport with tags , , , on February 27, 2018 by telescoper

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…

Winter Weather Contrasts

Posted in Biographical with tags , , , on January 18, 2013 by telescoper

The world-famous British weather has been pulling out all the stops over the last few days. During a short break in the proceedings yesterday I did a bit of flat-hunting in Brighton. It was a lovely bright morning, with the winter sun low in the sky making the city look absolutely beautiful. Here’s a pic I took with my Blackberry of the Palace Pier from Marine Parade…

I managed to get away at a reasonable hour after the end of the interviews and made it home to Cardiff before the snow arrived, which it eventually did around one o’clock in the morning. It’s still snowing a bit, actually, but it’s now mixed with drizzle. The slushy streets are unusually quiet. There’s not all that much in Cardiff itself, but the examinations due to start at 9am this morning were delayed until 9.30 to allow students and staff extra time to get to the various venues. The main thing is that it’s very dark, with grey clouds filling the sky. Here’s another Blackberry pic, taken on my walk into work this morning..

The contrast with Brighton yesterday is considerable, except for the temperature. Bright and dry in Brighton, dark and damp in Cardiff and cold in both.

Still, at least the “red snow alert” broadcast by the BBC came to nothing. This lot is definitely white.
