I'd have to disagree with the link to downpours. The injection of water vapour was in to the stratosphere, which is effectively insulated from the troposphere where our weather "happens". True that the volcano probably added to the water vapour content of the troposphere too, but the scale of that tropospheric injection was insignificant alongside everyday weather processes (such as evaporation and convection).HansR wrote: ↑Sun 06 Aug 2023 11:45 am This is a nice spin off of this eruption (holiday study) https://twitter.com/RARohde/status/1685971656198545408
And probably to the massive downpours as well (my addition)The Hunga Tonga–Hunga Haʻapai eruption was unusually water rich (& sulfur poor), injecting ~150 million tonnes of water into the stratosphere, increasing global upper atmosphere water mass by ~15%.
As a powerful greenhouse gas, this water may have contributed to recent warming.Schermafbeelding 2023-08-06 133745.png
