Any idea yet as to how much ash or SO2 has been put into the atmosphere so far.

Any comparison as to past volcano eruptions. Very impressive on satellite imagery.

Washington Post had a good write up. 400kilotons of SO2 so far. Pinatubo in 1991 put 1000 kilotons into the atmosphere.

Reports that the ash cloud reached 100k ft. That's almost unimaginable, thats more than twice the altitude I fly at, FL 450. It's higher than the "official" altitude record for the SR71.

The shockwave traveled around the world at 800mph, faster than the speed of sound.

I wonder if it affect our weather

This article may shed a little light on your question, but they admit there are still alot of unknowns.

NO GLOBAL COOLING

"Huge volcanic eruptions can sometimes cause temporary global cooling as sulfur dioxide is pumped into the stratosphere. But in the case of the Tonga eruption, initial satellite measurements indicated the amount of sulfur dioxide released would only have a tiny effect of perhaps 0.01 degree Celsius (0.02 Fahrenheit) global average cooling, said Alan Robock, a professor at Rutgers University."

No expected global cooling with the Tonga Volcano explosion

From the little I know on the topic- it's the high latitude volcanoes that do the damage with decreasing the temp of the earth quickly - however slightly. Tonga is not high latitude but given it's intensity, it should play an effect down the road, but not as much as Pinatubo.

Speaking of Tonga- underwater and all- it's still a mystery how these underwater volcanoes heat the oceans/currents which basically ='s weather/climate. Some say they are big player in the matter of how the oceans warm/cool. Others not so much.

With a major eruption near the equator - you usually get an EL NINO going. A decrease in solar radiation over the tropics will slow down the easterlies (winds) . If that happens = water will rise up in temp with winds blowing from the E. A lot going here.
Under Sea Volcanoes are something... We just don't witness them.

I feel like they were wrong about the no global cooling. It's been a very cold spring

Interesting thought.
