Global Temperature Page- June 2011

This page will be reposted around the middle of each month, as soon as SOI and UAH data for the previous month are available.

After some more consideration and tinkering with the methodology, I have fine tuned the prototype method a little.  As well, I realise it is foolish to attempt too much accuracy for a very chaotic system.  Therefore, my error margins are once again set to +/- 0.1C.

Note in this table  I have kept my previous values; I am experimenting with a slightly different method.

November 2011

0 +/- 0.1

As the SOI values change, I am looking forward to seeing how the UAH changes.  With the rapid change in SOI we have seen, we can expect either under or over shooting my calculations, or a change in timing.  All good data for improving my methodology!

Here is my new plot of 12 month mean temperature anomaly forecasts until the end of the year, as La Nina fades out and the SOI returns to neutral.  If the SOI again goes strongly positive, the temperatures will go lower. (In this graph, SOI is inverted).  

Note that there are some differences with previous plots due to my experimenting with a different methodology, resulting in better long term approximations, but 2010 values are different.  As my primary objective is to develop a method of approximating long term temperatures, short term variation is not so important.  But it is interesting!

(May plot)

It has become apparent to me that there is variation not only vertically (i.e. calculated values for a given month) but also laterally: the lag between SOI and temperature varies between 3 – 4 months and 7 – 8 months.  The system wobbles.

Please note- I started this method in March 2011.  Please refer to

I will expand on my method in a future post.
