A little side stat. The 2nd coldest ever AFL/VFL grand final was in 2002, with a top of 11.9c, a week after the SSW peaked over the south pole. Coldest grand final was in 1958 of 11.3c but this was before satellite technology, so we don't know if their was a SSW event at the time. These extreme's come down to timing with synoptics but thought it was interestingGordon wrote: ↑Fri Sep 06, 2019 12:47 pm This article just out on the ABC site https://www.abc.net.au/news/2019-09-06/ ... k/11481498 says the current Sudden Stratospheric Warming event is almost unprecedented (only one other to rival it recorded in 2002) but no mention of cold/ low level snow

Edit: It appears the speed of rotation of the outer areas of the vortex at both 70 and 10 hpa is slowing,
Is this related to or caused by El Nino? Or is it caused by the North pacific and Alaska Currents?StratoBendigo wrote: ↑Mon Sep 09, 2019 7:28 am The warm blob in the NE Pacific is doing a repeat of Sept 2014
