So, Dara: I'm afraid I'm going to ask you to your scalograms and graph using air pressure _anomaly_ data instead of air pressures. With air pressures, it does not relate to the Southern Oscillation Index in a nice way.

I'm talking about these:

"darwin-tahiti.jpg"



"darwin_dgauss.jpg"



"tahiti_dgauss.jpg"



It's fine if you don't do the Gabor wavelets: the Gaussian ones are enough for explaining the idea.

And I'd be happiest if you _did not_ "denoise" the data. For explanatory purposes it's simpler to work with raw data.

Darwin air pressure anomalies are [here](http://www.cgd.ucar.edu/cas/catalog/climind/darwin.anom.ascii), and Tahiti air pressure anomalies are [here](http://www.cgd.ucar.edu/cas/catalog/climind/tahiti.anom.ascii).

Don't forget to cut out the data after 2012!
