my colleague Jeremy Zakis, reporting on a phenomenon I have just come across,

reporting from the southern hemisphere. Sudden stratospheric warming. SSW is the acronym,

according to the Met Division in Sydney.

Jeremy, it is springtime. Lucky you in Australia. The flowers are coming out. The koalas are reproducing. The snakes are reproducing. And we're anticipating a good contest between all the English team

and the Australian team come November.

In the meantime, there is a phenomenon in Antarctica that's very much changing or disrupting

the weather patterns across Australia.

What is a sudden stratospheric warming, and what does it feel like? Good evening to you.

Githo John. Yes, the sudden stratospheric warming is exactly as it sounds. It's a sudden really quick

warming of the upper atmosphere. When I'm talking about upper atmosphere, I mean around about 100,000 feet in

altitude. So this is the very high areas.

And what has happened is we've had a 30 degree rise in the atmosphere up at 100,000 feet across Antarctica.

So what this means is it's gone from minus 158 degrees Fahrenheit to minus 104 degrees Fahrenheit in the space of only a couple of weeks,

which is very, very sudden for the Antarctica.

So what that now means for us is that all that warm air mass up above

means that the cooler air masses and the warmer air masses down below are all being disturbed,

degrees Celsius, so well above 100 degrees Fahrenheit on consecutive days that we saw in 2019,

which was also the summer of the catastrophic bushfire. So, John, for us, this is absolutely
