Good News : more cyclone swells , better drinking weather and mangoes for southern Oz.

Bad News : more difficult for inner Melbourne goths to exclusively wear the colour black due to greater temperatures .

ABC had an article on it here: http://www.abc.net.au/science/articles/2014/05/15/4005092.htm

Unpublished data from the Australian region suggests that the poleward shift is not as strong here as elsewhere in the Pacific around countries such as Fiji and New Zealand, but it could still have an impact, says Dr Hamish Ramsay of Monash University, who wrote an accompanying commentary in Nature.

"If this shift in poleward activity continues then cities and towns further south along the Australian coastlines may be susceptible to more destructive storms," says Ramsay.

Drawing a very long bow (and I'm extremely reluctant to do so), such a scenario would tip the hat slightly in favour of the East Coast's surf potential. But, I doubt it could be in any way measurable, for all of the reasons previously discussed about how flukey and unreliable swell prospects are from tropical cyclones.

Still, it's an interesting discussion point.

If we could just train all cyclones to sit off the coast in the area between top of NZ and Fiji we'd get pumping conditions every season for days on end. Not that big an ask is it?
