With what is happening on the far side of the world in Tonga does anyone think this could mess with current weather models.

Nope, doubt volcanic activity will make a difference unless we get deep cold nailed in on all models at 24+ then something will probabily go cataclysmically bang in Iceland and shunt it all east.....

 

Will be interesting to see what differences it made down that part of the world though in compareson to what was modelled and what came to be after.... 

 

Interesting to see ecm looking to get rid of our high, i can't really see anything that looks most likely from my novice reading of cthe charts so gonna go back towatching you guys decifer them

Seems like it

So that's a +1 to -1 mb oscillation off normal. Not bad, makes you wonder what deviation Krakatoa caused.

Can't find any stats unfortunately only vagueness

Bit of a pressure oscillation here recently, and basically the same pattern on stations around the country so it's not local meteorology. Could this be the pressure wave from the eruption? 

Same here.

Yes it is

Or Pinatubo in 1991, that was a VEI 6 I believe.

Are we due a major volcanic eruption? 

[Mapantz]

This might be a long shot, but there is no reason why my baro graph did this..

I have noted many other stations with a similar trend.. shockwave?

[weatherobsuk]

SkySat image appears to have been acquired ~2 hours *before* the 04:00 UTC 15 Jan 2022 #HungaTongaHungaHaapai. The whole central part of the island was missing, probably blown up in the 14 Jan 2022 explosions.

I wonder if it will have any impact on the weather in New Zealand and around the other Pacific Islands such as Fiji and Samoa?

It's mid summer and NZ is facing Cyclone Cody but it looks as though that will graze past the east of the North Island.

Is there any indication the eruption might have any impact on tropical cyclone formation and activity into the autumn?

[Southern Storm]

 

Interesting video, no hype, the video of the eruption that is at the end of the video apparently was shot five days earlier, but the rest is eye opening

And the sound of the explosion from fiji 500 miles away!

Don"t know if the timing is right but yesterday evening about 9.00pm I took dog out as she was very restless and asking to go out .When in garden she just stood there listening .  Even I could hear the unusual sound of all the chicken pheasants in the woods round about us issuing an alarm call.Occasionaly you"ll hear one at night as a fox or pine martin gets too near its roost but not in these numbers. Thought it was a jet breaking the sound barrier/explosion  upsetting them but could it have been the eruption?

Not sure,  but the Volcanoes are Boiling all over the World , dare I say Yellowstone ???

Nope tooo far away.

The Volcano went off at 04:00UT but Pheasant do start making noise at shockwaves. When I was a kid Concord going supersonic out in The Channel used to set them off nightly.

I saw a similar pressure anomaly too.

Damn all that hard work I did building the island and I sneeze and look what happens.

Yes it's registered all over the UK

I don't know about the timing, but I believe shock waves travel through the earths crust very quickly, however the sound pressure wave looks like it only recently passed through.

I wouldn't be surprised if animals could sense a volcano blowing it's top off on the other side of the world at short notice

Ah, yes. I just read the post further up.. I was in a hurry and didn't read. I just saw my graph and thought wtf. Crazy!

I'm saving that graph!

Bit difficult to say if we are "due" a major eruption as volcanoes are so unpredictable. Some individual volcanoes have fairly regular patterns but overall, it's not possible to tell.

I don't think this is anywhere near as powerful as krakatoa. That said krakatoa was only a fifth the strength of the santorini cataclysm

This looks to be a 5, Krakatoa was a 6.

For comparison, Mount St Helens was a 5, Pinatubo a 6, the recent La Palma a low 3.

Yellowstone last eruption, an 8.
