North Atlantic Oscillation

I started a page on NAO. boilerplate sofar but feel free to update

    There's also something called AMO. I'll have to read about both to see what's the difference between NAO and AMO.

    Because

    AMO is a fluctuation in the sea surface temperature in the North Atlantic Ocean.

    I thought they could be related, but the plots have a different pattern (though a similar abscis) so I guess not.

    But @Staffan: what's the ordinate of the plot on NAO?

    Wikipedia says "The North Atlantic Oscillation is closely related to the Arctic oscillation (AO) or Northern Annular Mode (NAM), but should not be confused with the Atlantic Multidecadal Oscillation (AMO)."

    The AMO has a period of 70 years. According to Hurrell et al, "The spectrum of the winter-mean NAO index is slightly “red”, with power increasing with period. It reveals somewhat enhanced variance at quasi-biennial periods, a deficit in power at 3 to 6 year periods, and slightly enhanced power in the 8-10 year band, but no significant peaks." This is consistent with the messy look of the graph.

    Staffen: thanks for writing a nice big page full of juicy information! I hadn't even heard of the NAO.

    Here are some tips for writing Azimuth Project entries:

    1) Read HowTo, which is full of information on how to do things.

    2) If you want to quote someone, use a quote box:

    According to the introduction by James W. Hurrell _et al._, cited below:
    
    +-- {: .quote}
    
    The North Atlantic Oscillation (NAO) is one of the most prominent and recurrent patterns of atmospheric     circulation variability. It dictates climate variability from the eastern seaboard of the United States to Siberia and from the Arctic to the subtropical Atlantic, especially during boreal winter, so variations in the NAO are important to society and for the environment.   
    
     =---
    

    See the NAO page for what this achieves.

    3) If a paper is written by several authors, say "Hurrell et al." instead of "Hurrell". It's annoying being a coauthor and not getting named... but even more annoying when your existence isn't even acknowledged! We want to make friends with the people who write these papers, so we should be nice to them.

    4) It's nice to center figures, and even more important to provide clickable links to the figures: all data on the Azimuth Project must come with sources, so people who question this data know how to dig deeper. This is especially important in climate science. This is the style I use:

    <div align = "center">
    <a href = "http://en.wikipedia.org/wiki/File:Winter-NAO-Index.svg">
    <img src = "http://upload.wikimedia.org/wikipedia/commons/thumb/8/87/Winter-NAO-Index.svg/500px-Winter-NAO-Index.svg.png" alt = ""/>
    </a>
    </div>
    

    5) When copying text from a PDF file, note how errors get introduced:

    Spatially, the main model def"ciency is that the simulated NAO has a teleconnec-tion with the North Paci"c that is stronger than ob-served. In a temporal sense the simulation is compat-ible with the observations...

    More importantly, if we text that someone else has written, we need to make clear that it's a quote. We should not be plagiarizing people!

    I've attempted to fix these problems on the NAO page, although there's one place where I had trouble knowing when a quote started.

    I've also tried to put the references into our standard style:

    gives

    Note:

    • Include journal references whenever possible (I'm sure it's possible for most of these, but I was too lazy to look up the information except in two cases).

    • Put the link on the paper title when clicking on that link will give the paper for free; put it on the journal's name when it only takes you to the journal and you need a subscription to read the paper.

    • Various stuff about standard reference styles...

    Also:

    If you hate all of this stuff, don't do it!

    I'd rather have people enter material and fix things up myself, than have them not enter material! I'm a bit of a perfectionist (as you might have noticed), but we're supposed to be having fun here.

    Of course I also hope some people help me clean up existing pages. I find it easy and fun to do this while reading those pages... but as the Azimuth team grows, we'll need the clean-up team to grow in proportion to the number of people making pages.

    Thx John for the kudos and help. I was trying to look up the right way to quote instead of just " ..." and i found most of the pdf errors but appearantly not all :-). I will fix the rest

    Btw, Staffan, there was text that seemed quoted but didn't have quotes around it, near the end. I tried to paraphrase that, but you could also revert back to the original quoted text and put it into the "quote box".

    Anyway: I know about NAO, now!

    The Azimuth Project server seems to have crashed; I'll try to reboot it.
