Found a Brazilian mult-vort wedge video:

I've always been fascinated by tornadoes and other severe weather in the Southern Hemisphere. Not only in Australia, but also in South Africa and South America, too.

About that link Damon posted originally, there is an English version of that Brazilian site - and interestingly, it has even more pics of Brazilian tornadoes than the Portuguese language version! (unfortunately, the additional links aren't in existence when you click on the additional pics)

Also a link to a supercell in Argentina:

As for that video of the Brazilian tornado, I knew about this since late May from another non-weather forum which is regularly visited by a highly international mix of users, including Brazilians. That tornado in the video looks somewhat like the 1987 Edmonton tornado (see my avatar!).

I'd imagine that not only would tornadoes rotate cyclonically in the Southern Hemisphere, but also the supercells as well, and I also believe they'd have a reverse configuration to their counterparts north of the Equator. I believe I've seen this kind of reverse configuration happen in Australian supercells, especially in Doppler radar images from southeast Queensland (around Brisbane), New South Wales and Victoria. It's all in the Coriolis Effect.

Rafael Ketelhohn is a chaser in Argentina that posts some good shots to the Lightning list from time to time. They seem to have active storm patterns year round with multi-day events common.

Not sure if Rafael is on ST, but here is his site:

Rafael has a great vantage point from his house and has got some nice lightning shots.

It's insane to think about Severe Weather in other parts of the world. The United States always has the dominance on the reporting of severe weather and our "Tornado Alley"

But some of the world's most violent storms actually occur more so in Coastal Australia.
