700km away the bang sounded like this....
Interesting they knew they eruption occurred, they apparently see clouds associated with it, but the sound waves arrive later?
Assuming a 700mph speed of sound, I guess about 45 mins or so for the sound to travel 700km.

Urgh....gavin schmidt...
Jc posted this however, so, until other data comes in, Tonga looks weak on SO² emissions so maybe not a climate influence.

None the less, impressive boom. PS. I can now see Twitter posts again. Did someone fix something?

The wave reached North Dakota!!!! And New York mesonet.
The energy to provide an atmospheric disruption world wide is......................... a lot???

Sitting outside last night drinking with a bunch of friends on an island in the north of NZ and we heard thunder but no clouds or lightening it was the volcano quite amazing when you think of the distance.
Our Jetty remained clear of water and our boat was fine but others not so lucky.
We drank and went to bed oblivious to the drama.
This is a strat volcano so the aerosols will be up there and the latitude is also good for circulation. Maybe a good test of the volcano and climate theory.

This was an undersea volcano.
It would have propelled a lot of salt into the stratosphere. [also fine ash].
What climate effect might that have?

Is there a reporting satellite sensor for such things ... or those who estimate such from existing sensors? Should affect electro-magnetic reflection / absorption in specific bandwidths. |

Thinking about the Tongan volcano.
Clearly it is large, to send material up 19kms, and sufficiently explosive to be heard in Fiji.
The modest assumption is made that about one cubic km of seawater was vaporised and sent upstairs, [which figure could be horribly wrong in any direction]:
this would be 1,000 million tons of seawater containing about 30 million tons of salt, excluding other stuff and fish.
It is hard to believe that quantity of salt in the stratosphere will have little impact, especially as it does not include a large volume of ultra-fine ash.

Early estimates indicate this had a VEI of at least 4. I believe Krakatoa was a 6. Tambora which led to the Year Without A Summer was a 7. Pinatubo in 1991 was a 6.
So it would stand to reason if this ends up being a 5 it should have at least some cooling effect on the climate. We will see. Warmist's will try to downplay it, Denialist's will overestimate it. We will wait and see how this effects Tropospheric temperatures over on Dr. Roy Spencer's site.

I have been looking at this Tongan volcano and its impacts. The CO2 emission are on a net basis likely to be negative and massively so the ash cloud will have a significant volume of Fe and the drift direction from earth.nullschool.net/#current/wind/isobaric/700hPa/orthographic=-165.00,0.00,482/loc=-175.044,-23.884 Will be south into the Fe deficient Pacific region. The forest fires in Australia two years ago were basically "net zero" due to the same process of phytoplankton growth etc. from the Fe in smoke, this will be many orders of magnitude larger. Additionally the seas will produce a lot of fish both helping the whales and mankind. In NZ we should start seeing spectacular sunsets and sunrises in a day or two as a Cyclone is wandering past currently with it airflow starting in Tonga. Current airspeed at 500hPa 50Km/Hr 3 days aprox. 2 to go. the good thing is that the winds at each level seem to travel every which way so big area of deposition. Tonga will be hit hard but the ash will bring a bounty of fertility and the bulk of Tongans live in NZ who basically bankroll the country, the capital repatriations are the biggest part of Tongan economy. It will need a boost clearly till the crops return. Their Vanilla industry will take a little longer. |

Lazy Ratty: Non, can you point me in the direction of something interesting to read about the Fe/oceans/fish? |
