A very brief break in the Sc sheet today

[Dorsetbred]

Well, what a let down after a couple of classic January winter style days, overcast has returned..

The overnight low of 0.1°C at: 06:52, left a decent ground frost, in fact I was down B&Q by 8am and the car park was a skating rink, with the humidity and low temperatures. Anyway the temperatures made it up to the seasonal norm of 7.1°C at: 15:20, so the T-shirt and shorts withstood the average temperature, even though my wife came inside complaining of frozen fingers!

Still overcast, so unlikely a frost tonight unless the breeze kicks it's @rs3 , currently 6.9°C with the RH84% and a 3mph breeze in from the east..

As posted in the volcanic thread..

That's the shockwave from the explosion in Tonga, 10,300 miles away.

Was down Warminster way this morning a very crisp and sunny start to the day.

Have you seen the images of the explosion?

I certainly have! 

Spectacular to say the least..  I expect more & more videos and images will appear over the coming days?!

[Mapantz]

Some rain and a breeze has finally shifted the awful air quality away..

Coo I had missed that volcano! Pretty mad that!

[knocker]

Breezy with a fair amount of Stratus flitting across

[Dorsetbred]

Second shock wave from the volcanic eruption came through last night..

I have learnt something new with this occurrence. We truly are only tenants on Earth aren’t we!

Interesting to read the above posts about the volcano pressure spike.
Had a look at mine just after 7pm and was steady at 1024.3, a spike to 1025.7 for around half hour and then back to 1024.4

1mm rain around 1am and 2am this morning.
Now, grey, dry, 8.3c, WNW 2-4mph, 1025.2 hpa

Much of the cloud now cleared, just some broken Sc. Quite pleasant

And seemingly not very good ones at that either!

Educate me on these shock waves and how we can feel them from here?

[Mapantz]

Temp managed to get up to 11.9°C in the sunshine. Felt very nice!

[Skullzrulerz]

With the exception of a rain shower overnight yesterday, it's been quite nice over the past few days.

Temperatures have been somewhat on the chilly as of late but it has warmed up a tad today

You mean the earth didn't move for you... not ONCE but TWICE....

OOPS sorry

You are doing well, been really cloudy here, ALTHOUGH  we did get a sunny break earlier but our best is 10.6°C at: 13:42

Ok, so when something goes BOOM, aka BIG bang, it makes the air particles oscillate, nudging the air particle next to it, which nudges the one next to it, and it in turn nudges the next...well you get the picture.. With such BIG bang force, pressure waves are forced out, and they figure in times of Covid, when most people need a mask to travel, "Hey s0d that, we can roam freely" so off they go in every direction, chasing atmospheric particles, which in turn ride the wave, just like they do in Cornwall, as the wave goes up, and then down..

As it happened this time, the effect for people in the UK was minimal, so using our auditory device (aka ears), the pressure change was too small for us to notice, hence we never heard the BIG bang , but as noted weather stations measure pressure anomalies were able to capture the change of the pressure wave, hence the rise (increase in pressure as the wave approaches, and a decrease in pressure as the wave goes past).

OR a simple explanation

How do pressure waves work?

Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.

Got it Fred! Gotta love a Physics lesson. My Physics teacher ... Mr Aspin ... he used to be very hot he did! I liked physics me ...

Clear sky, frost and little wind

Yea we don't pay rent ..(we do that to each other )..and nick the furniture as well ,leave nothing ..then a couple or few million years later...next people arrive ..all we have done is gone ..16000 ft.under ground..southern England is where alaska is now ..and it all starts again ..if only we paid up ..:-(   

Only joking ..I wouldn't like to be the caretaker though...:-)
