Excellent visibility and striking cloud-scapes made for a lovely, if a
little cold at times (though maximum did reach 9.3C) day.

A few very brief but intense hail showers and lots of dazzlingly clear
blue sky and strong sunshine in-between.

After seeing Alan's rather superb time-lapse videos I thought I would
have a go but my webcam doesn't quite have the quality of a 'Go Pro'
camera, especially as it looks through the double-glazing of one of the
rear-facing bedrooms. And my resolution was set to a rather lowly
1280x720. Anyway, I've uploaded a time-lapse video of the whole daylight
hours with a rate of 1 photo per second and a film speed of 60 frames
per second. Hence 1 second = 1 minute of real time.

The video is 7 minutes long and composed of 30,000 photos. I'll do
another tomorrow at HD 1920x1080 resolution.

Hypnotic!

A very interesting sequence with weak cold advection (slight wind
backing with height) at first, increasing during the morning so
convective depth increasing then, in the afternoon, a shift in the
upper cloud movement to northerly and hence, strong warm advection.

When I was younger, I'd watch out for the winds changing with height
like this and see there was cold advection going on and wait for the
showers to intensify and turn from rain to sleet and then to snow.

Sometimes there was no upper cloud to go on but there might be
noticeable cloud streets to watch. If the W-E lines of showers were
edging southwards, that was also a sign of cold advection (the streets
being aligned with thickness lines) and the same development could be
witnessed as I mentioned before.

I'd be pretty pleased with that, especially if it's a first attempt.
Very good, especially for a humble webcam.

This could catch on! Lovely video, Nick. The clouds are magic. Thanks for sharing.

Damn, you beat me to it :-) My next attempt was to power the camera from
it's charger and to record twelve hours-worth but that depends on
getting twelve hours with no precipitation.

Excellent vid, thanks.

Now I've moved into a new place that actually has a significant view of
the sky, albeit mostly to the NE, I guess I should break out my old
time-lapse camera too.

Joe - I was thinking a similar thing. More time-lapse, please!
