Don, thanks for posting this paper. I added a link to another recent paper on this topic.

Don - thank you for posting that link, there is a mountain of good stuff there and it will occupy my idle moments for a long while.

Bluewave - I couldn't get your link to work. The problem may be on my end - this old computer is practicaly steam-powered.

Both good additions - FWIW both opened properly using my antiquated system.

thanks for the links guys, so much data to comb through in a nice package.

Thanks for the links Don and Bluewave! Very interesting papers.

Although I didn't read every word of both papers, I was a bit surprised I didn't see anything on the increase in blocking with climate change. It's one of the more convincing arguments for "global extreming" I've heard. The flow of logic is that:

- The poles warm more rapidly than the equator, decreasing the meridional temperature gradient

- Assuming surface wind does not change much (due to surface friction), the zonal jet must weaken to maintain thermal wind balance

- A weaker jet leads to more cutoff lows and omega/rex blocks

- Increased blocking favors more extreme, long-lasting heavy precip events where troughs go stationary, droughts with ridges

Can't remember the reference right now, I'll try to find it.

Stu Ostro has also done a great job documenting the blocking patterns. The PDF is very large so it takes time to load.

Thanks!
