When I first heard about global warming, the physicist in me said, hmm, the major effect of this will be energetic weather systems will become more energetic.

Now put that together with my personal experience of extreme weather events both in NZ and ZA, the jet streams has _always_ been involved.http://squall.sfsu.edu/scripts/shemjetstream_model.html

ie. If I see a major stream coming near me... Big Stuff happens with the weather. If something extreme is happening with the weather, I check and a big stream is going very near by.

ie. I expect we will see more interesting stuff happening with the jet stream as the climate cooks.
