Without searching online or editing, see how many Long Range/intraseasonal acronym's you can remember from the list below. When I have time, i will try to post some informal papers/info on each indice. Good Luck to everyone and may the sharpest member win!

I've heard about almost all of them at some point... the only ones I can actually remember more than their name are bolded above. Long range forecasting is certainly a fascinating subject especially with all the research put into it, both the typical indices listed above and the additional methods as discussed in the Long Range forum (i.e. BSR/TR/ISO/etc.), although the whole field of long range forecasting appears extremely complex from the perspective of an amateur, and I'm split between deciding whether to dedicate more time to pursuit long range forecasting or stick with trying to improve the precise details in short-medium range forecasting, which still has quite a bit of issues itself (March 2nd epic fail).

Just a thought I've been having, which I don't know if it's even valid or not, although I've always wondered if there was a way to bridge the two, as in using analyses of the long range indices to improve the medium-long range global models - the GFS at day 15 may sometimes offer clues about the global pattern but I've rarely seen it useful in the synoptic scale (besides coincidence on storm dates).

16 months ago, I would have only known a handful. I can name most of them now, the stratospheric and global wind indices I learned from reading posts by you, the snowman, and weatherjunkie, and then researching to learn more about them.

The El Niņo indices have moved to the front of the line lately, so I'm getting much more knowledgeable about those daily.
Is the NPI also an El Niņo index? Also is a CTW, a type of convective ocean wave?

Really looking forward to learning more about all these fun acronyms. If it's alright, I have accumulated resources for many of these indices, and I would love to share any information and links here. I nearly started a personal discussion to put all the pdf and links somewhere that others could see and add.

Hope you don't mind lots of questions smile.gif

Questions are encouraged, and feel free to add any links you want! The NPI is a measure of the strength of the aleutian high/low. Positive values indicate a weaker low and a tendency to see more ridging across the area. Have never heard of a CTW, but i would assume its a type of subsurface wave like an OKW/RW.
