MY EL NINO/LA NINA/NEUTRAL RESEARCH IS FINISHED

[JTD]

South, very informative and excellent research!! Thanks for sharing.

Thank you jason..

I am almost finished with my complete list of storms on excel spreadsheet with all kind of data for you data guru's. I will be posting it tonight.

If anyone has a list of elnino and lanina years before 1950 then i could do some more averages and add them to my elnino/lanina spreadsheet.

Warm (red) and cold (blue) episodes based on a threshold of +/- 0.5oC for the Oceanic Niño Index (ONI) [3 month running mean of ERSST.v2 SST anomalies in the Niño 3.4 region (5oN-5oS, 120o-170oW)], based on the 1971-2000 base period. For historical purposes cold and warm episodes (blue and red colored numbers) are defined when the threshold is met for a minimum of 5 consecutive over-lapping seasons

I see that you are using the definition and data from the NOAA CPC site, but, may I ask how you decided what an el Nino "year" and a la Nina "year" was based on that data ????

I also got the el nino/la nina data from the following site...

it might also be interesting to look at landfalls based on tropical atlc ssts (or other regions) in june/july or perhaps may.

That is true benny but, it is going to require some more time and research to do so. I will try to get it done.

Here is the longer SST dataset

I believe you would have to calculate your own anomalies (using whatever mean you had beforehand) and just take the running means that NOAA uses to come up with your own long table. You might also consider de-trending the data a little b/c the SSTs were a little cooler in the early part of the century and last.
