[ Snip ] Ratty walking out over the Brisbane pack ice to the Barrier Reef? Sounds like a climate emergency; I'd better go find my Superglue.

What are your thoughts, Non? If you use the calendar function, the 2nd counter rotating vortex can be seen back to the 22nd august or so. The ssw started just a bit later, certainly in full flow by 1st september. Its seems either the instability caused ssw, or, the cause of the ssw showed as instability prior to it effecting strat temps. Having paid attention to what is said by atmospheric scientists during the february NH SSW, id suggest they actually arent sure either.....

Yes I agree.
ultimately its the butterfly in the Amazon discussion but like the idea that you have run clock back searching for a starter, tricky and rare.

Emphasis on "may". Effects from SSW, when they do propogate to trop, tend to relatively localised with the upper latitudes. Lot of water in SH....nothing might be apparent on any landmass...

strat warming is normal .. it will dissipate the Antarctic polar vortex Ummm....not sure flea... I'm pretty sure something has dissipated and arrived here: Queensland bushfires see 11 schools close as battle to contain blazes continues "We could be seeing winds as high as 30 to 45kmh in parts of the south east of the state and gusting of up 50 to 60kmh in the afternoon.
"We still have to be extremely cautious and aware that the fire dangers are still quite elevated and it's quite a serious situation.
"Even into Tuesday when the winds moderate a little bit we're still talking about very high fire dangers so there's still a couple days to go of challenging fire conditions for much of eastern Queensland.
"We may see some moderation in the fire danger in particular on Wednesday, the winds are expected to decrease significantly, the fire dangers across large parts of eastern and south-eastern Queensland should drop to high which is average for this time of year."

Actually it seems to be not uncommon - I thought I recognized the pattern ... December 2016 Northern Hemisphere: September 2019 Southern Hemisphere Interesting
